Vulnerability from variot

Multiple stack-based buffer overflows in the (1) send_dg and (2) send_vc functions in the libresolv library in the GNU C Library (aka glibc or libc6) before 2.23 allow remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted DNS response that triggers a call to the getaddrinfo function with the AF_UNSPEC or AF_INET6 address family, related to performing "dual A/AAAA DNS queries" and the libnss_dns.so.2 NSS module. GNU glibc is an open source C language compiler released under the LGPL license agreement. It is an implementation of the C library in the Linux operating system. An attacker can use the vulnerability to launch an attack on a Linux host or related devices by constructing a malicious DNS service or using a man-in-the-middle attack, which results in remote code execution and can be obtained.

Here are the details from the Slackware 14.1 ChangeLog: +--------------------------+ patches/packages/glibc-2.17-i486-11_slack14.1.txz: Rebuilt. This update provides a patch to fix the stack-based buffer overflow in libresolv that could allow specially crafted DNS responses to seize control of execution flow in the DNS client (CVE-2015-7547). However, due to a patch applied to Slackware's glibc back in 2009 (don't use the gethostbyname4() lookup method as it was causing some cheap routers to misbehave), we were not vulnerable to that issue. Nevertheless it seems prudent to patch the overflows anyway even if we're not currently using the code in question. Thanks to mancha for the backported patch.

Business recommendation:

We want to thank Cisco for the very quick and professional response and great coordination. Customers are urged to update the firmware of their devices.

Vulnerability overview/description:

1) Hardcoded Credentials The device contains hardcoded users and passwords which can be used to login via SSH on an emulated device at least.

During the communication with Cisco it turned out that: "Accounts like the 'debug-admin' and 'root' can not be accessed from console port, CLI or webui". Therefore, these accounts had no real functionality and cannot be used for malicious actions. The outdated version was found by IoT Inspector. The outdated version was found by IoT Inspector.

Synopsis

Multiple vulnerabilities have been found in the GNU C library, the worst allowing for remote execution of arbitrary code.

Affected packages

-------------------------------------------------------------------
 Package              /     Vulnerable     /            Unaffected
-------------------------------------------------------------------

1 sys-libs/glibc < 2.21-r2 >= 2.21-r2

Description

Multiple vulnerabilities have been discovered in the GNU C Library:

  • The Google Security Team and Red Hat discovered a stack-based buffer overflow in the send_dg() and send_vc() functions due to a buffer mismanagement when getaddrinfo() is called with AF_UNSPEC (CVE-2015-7547).
  • The strftime() function access invalid memory when passed out-of-range data, resulting in a crash (CVE-2015-8776).
  • An integer overflow was found in the __hcreate_r() function (CVE-2015-8778).
  • Multiple unbounded stack allocations were found in the catopen() function (CVE-2015-8779).

Please review the CVEs referenced below for additional vulnerabilities that had already been fixed in previous versions of sys-libs/glibc, for which we have not issued a GLSA before. The other vulnerabilities can possibly be exploited to cause a Denial of Service or leak information.

Workaround

A number of mitigating factors for CVE-2015-7547 have been identified. Please review the upstream advisory and references below.

Resolution

All GNU C Library users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose ">=sys-libs/glibc-2.21-r2"

It is important to ensure that no running process uses the old glibc anymore. The easiest way to achieve that is by rebooting the machine after updating the sys-libs/glibc package.

Business recommendation:

SEC Consult recommends to immediately apply the available patches from the vendor. A thorough security review should be performed by security professionals to identify further potential security issues.

Vulnerability overview/description:

1) Authenticated Command Injection (CVE-2021-39279) An authenticated command injection vulnerability can be triggered by issuing a GET request to the "/forms/web_importTFTP" CGI program which is available on the web interface. An attacker can abuse this vulnerability to compromise the operating system of the device. This issue was found by emulating the firmware of the device.

2) Reflected Cross-Site Scripting via Manipulated Config-File (CVE-2021-39278) Via a crafted config-file, a reflected cross-site scripting vulnerability can be exploited in the context of the victim's browser. This config-file can be uploaded to the device via the "Config Import Export" tab in the main menu.

3) Known GNU glibc Vulnerabilities (CVE-2015-0235) The used GNU glibc in version 2.9 is outdated and contains multiple known vulnerabilities. One of the discovered vulnerabilities (CVE-2015-0235, gethostbyname "GHOST" buffer overflow) was verified by using the MEDUSA scalable firmware runtime.

4) Multiple Outdated Software Components Multiple outdated software components containing vulnerabilities were found by the IoT Inspector.

The vulnerabilities 1), 2) and 3) were manually verified on an emulated device by using the MEDUSA scalable firmware runtime.

Proof of concept:

1) Authenticated Command Injection (CVE-2021-39279) The vulnerability can be triggered by navigating in the web interface to the tab:

"Main Menu"->"Maintenance"->"Config Import Export"

The "TFTP Import" menu is prone to command injection via all parameters. To exploit the vulnerability, an IP address, a configuration path and a filename must be set. If the filename is used to trigger the exploit, the payload in the interceptor proxy would be:

http://192.168.1.1/forms/web_importTFTP?servIP=192.168.1.1&configPath=/&fileName=name|ping localhost -c 100

2) Reflected Cross-Site Scripting via Manipulated Config-File (CVE-2021-39278) The vulnerability can be triggered by navigating in the web interface to the tab:

"Main Menu"->"Maintenance"->"Config Import Export"

The "Config Import" menu is prone to reflected cross-site scripting via the upload of config files. Example of malicious config file:


[board] deviceName="WAC-2004_0000" deviceLocation="" [..]


Uploading such a crafted file triggers cross-site scripting as the erroneous value is displayed without filtering characters.

3) Known GNU glibc Vulnerabilities (CVE-2015-0235) GNU glibc version 2.9 contains multiple CVEs like: CVE-2016-1234, CVE-2015-7547, CVE-2013-7423, CVE-2013-1914, and more.

The gethostbyname buffer overflow vulnerability (GHOST) was checked with the help of the exploit code from https://seclists.org/oss-sec/2015/q1/274. It was compiled and executed on the emulated device to test the system.

4) Multiple Outdated Software Components The IoT Inspector recognized multiple outdated software components with known vulnerabilities:

BusyBox 1.18.5 06/2011 Dropbear SSH 2011.54 11/2011 GNU glibc 2.9 02/2009 Linux Kernel 2.6.27 10/2008 OpenSSL 0.9.7g 04/2005 Only found in the program "iw_director" OpenSSL 1.0.0 03/2010

LeftHand OS 12.6 - patch 56001\n  - LeftHand OS 12.5 - patch 55015\n\n  **Notes:**\n\n  - These patches will upgrade glibc to 2.12-1.166 to resolve this issue. ============================================================================\nUbuntu Security Notice USN-2900-1\nFebruary 16, 2016\n\neglibc, glibc vulnerability\n============================================================================\n\nA security issue affects these releases of Ubuntu and its derivatives:\n\n- Ubuntu 15.10\n- Ubuntu 14.04 LTS\n- Ubuntu 12.04 LTS\n\nSummary:\n\nGNU C Library could be made to crash or run programs if it received\nspecially crafted network traffic. \n\nUpdate instructions:\n\nThe problem can be corrected by updating your system to the following\npackage versions:\n\nUbuntu 15.10:\n  libc6                           2.21-0ubuntu4.1\n\nUbuntu 14.04 LTS:\n  libc6                           2.19-0ubuntu6.7\n\nUbuntu 12.04 LTS:\n  libc6                           2.15-0ubuntu10.13\n\nAfter a standard system update you need to reboot your computer to make\nall the necessary changes. \n\nReferences:\n  http://www.ubuntu.com/usn/usn-2900-1\n  CVE-2015-7547\n\nPackage Information:\n  https://launchpad.net/ubuntu/+source/glibc/2.21-0ubuntu4.1\n  https://launchpad.net/ubuntu/+source/eglibc/2.19-0ubuntu6.7\n  https://launchpad.net/ubuntu/+source/eglibc/2.15-0ubuntu10.13\n. \n\n\nHere are the details from the Slackware 14.1 ChangeLog:\n+--------------------------+\npatches/packages/glibc-2.17-i486-11_slack14.1.txz:  Rebuilt. \n  This update provides a patch to fix the stack-based buffer overflow in\n  libresolv that could allow specially crafted DNS responses to seize\n  control of execution flow in the DNS client (CVE-2015-7547).  However,\n  due to a patch applied to Slackware\u0027s glibc back in 2009 (don\u0027t use the\n  gethostbyname4() lookup method as it was causing some cheap routers to\n  misbehave), we were not vulnerable to that issue.  Nevertheless it seems\n  prudent to patch the overflows anyway even if we\u0027re not currently using\n  the code in question.  Thanks to mancha for the backported patch. \n  For more information, see:\n    http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-7547\n  (* Security fix *)\npatches/packages/glibc-i18n-2.17-i486-11_slack14.1.txz:  Rebuilt. \npatches/packages/glibc-profile-2.17-i486-11_slack14.1.txz:  Rebuilt. \npatches/packages/glibc-solibs-2.17-i486-11_slack14.1.txz:  Rebuilt. \n+--------------------------+\n\n\nWhere to find the new packages:\n+-----------------------------+\n\nThanks to the friendly folks at the OSU Open Source Lab\n(http://osuosl.org) for donating FTP and rsync hosting\nto the Slackware project!  :-)\n\nAlso see the \"Get Slack\" section on http://slackware.com for\nadditional mirror sites near you. \n\nUpdated packages for Slackware 14.1:\nftp://ftp.slackware.com/pub/slackware/slackware-14.1/patches/packages/glibc-2.17-i486-11_slack14.1.txz\nftp://ftp.slackware.com/pub/slackware/slackware-14.1/patches/packages/glibc-i18n-2.17-i486-11_slack14.1.txz\nftp://ftp.slackware.com/pub/slackware/slackware-14.1/patches/packages/glibc-profile-2.17-i486-11_slack14.1.txz\nftp://ftp.slackware.com/pub/slackware/slackware-14.1/patches/packages/glibc-solibs-2.17-i486-11_slack14.1.txz\n\nUpdated packages for Slackware x86_64 14.1:\nftp://ftp.slackware.com/pub/slackware/slackware64-14.1/patches/packages/glibc-2.17-x86_64-11_slack14.1.txz\nftp://ftp.slackware.com/pub/slackware/slackware64-14.1/patches/packages/glibc-i18n-2.17-x86_64-11_slack14.1.txz\nftp://ftp.slackware.com/pub/slackware/slackware64-14.1/patches/packages/glibc-profile-2.17-x86_64-11_slack14.1.txz\nftp://ftp.slackware.com/pub/slackware/slackware64-14.1/patches/packages/glibc-solibs-2.17-x86_64-11_slack14.1.txz\n\nUpdated packages for Slackware -current:\nftp://ftp.slackware.com/pub/slackware/slackware-current/slackware/a/glibc-solibs-2.23-i586-1.txz\nftp://ftp.slackware.com/pub/slackware/slackware-current/slackware/l/glibc-2.23-i586-1.txz\nftp://ftp.slackware.com/pub/slackware/slackware-current/slackware/l/glibc-i18n-2.23-i586-1.txz\nftp://ftp.slackware.com/pub/slackware/slackware-current/slackware/l/glibc-profile-2.23-i586-1.txz\n\nUpdated packages for Slackware x86_64 -current:\nftp://ftp.slackware.com/pub/slackware/slackware64-current/slackware64/a/glibc-solibs-2.23-x86_64-1.txz\nftp://ftp.slackware.com/pub/slackware/slackware64-current/slackware64/l/glibc-2.23-x86_64-1.txz\nftp://ftp.slackware.com/pub/slackware/slackware64-current/slackware64/l/glibc-i18n-2.23-x86_64-1.txz\nftp://ftp.slackware.com/pub/slackware/slackware64-current/slackware64/l/glibc-profile-2.23-x86_64-1.txz\n\n\nMD5 signatures:\n+-------------+\n\nSlackware 14.1 packages:\n4c56432d638adc8098661cfa818b5bc9  glibc-2.17-i486-11_slack14.1.txz\n5c316d6b0a8970fe15fbdf2adff8de19  glibc-i18n-2.17-i486-11_slack14.1.txz\na937d842e5ca3d0b125230c23285f8f4  glibc-profile-2.17-i486-11_slack14.1.txz\n442f01d094d350612c1fb1fcb5e7fbe7  glibc-solibs-2.17-i486-11_slack14.1.txz\n\nSlackware x86_64 14.1 packages:\neec88d584a79909ec79aae1c43c330d3  glibc-2.17-x86_64-11_slack14.1.txz\nd8b396eb6ada65d1555e3cf0fb8246c2  glibc-i18n-2.17-x86_64-11_slack14.1.txz\ne7deaabfe3e467cbde10ba5b7748bbbb  glibc-profile-2.17-x86_64-11_slack14.1.txz\n629c93f0e510d354ff66e61f1ebe8b67  glibc-solibs-2.17-x86_64-11_slack14.1.txz\n\nSlackware -current packages:\nb11873e4f851a600b57a2e7a2ac8f472  a/glibc-solibs-2.23-i586-1.txz\n5116eec63fab5e7dbc58d27fecd48684  l/glibc-2.23-i586-1.txz\nae9b8a8e4ead59aa398212d6893d7ddc  l/glibc-i18n-2.23-i586-1.txz\n61154e43ee4c0739dd5d3c4ce3b60ae6  l/glibc-profile-2.23-i586-1.txz\n\nSlackware x86_64 -current packages:\nc48a55c8a39dc8e17e04796e4f160bd0  a/glibc-solibs-2.23-x86_64-1.txz\n36104e1a004b0e97d193c2132f18222d  l/glibc-2.23-x86_64-1.txz\ne0415f66d17323c8f6df339cfd49051b  l/glibc-i18n-2.23-x86_64-1.txz\nf5433793e9da696a60f2445559f1d33f  l/glibc-profile-2.23-x86_64-1.txz\n\n\nInstallation instructions:\n+------------------------+\n\nUpgrade the packages as root:\n# upgradepkg glibc-*.txz\n\n\n+-----+\n\nSlackware Linux Security Team\nhttp://slackware.com/gpg-key\nsecurity@slackware.com\n\n+------------------------------------------------------------------------+\n| To leave the slackware-security mailing list:                          |\n+------------------------------------------------------------------------+\n| Send an email to majordomo@slackware.com with this text in the body of |\n| the email message:                                                     |\n|                                                                        |\n|   unsubscribe slackware-security                                       |\n|                                                                        |\n| You will get a confirmation message back containing instructions to    |\n| complete the process.

The other vulnerabilities can possibly be\nexploited to cause a Denial of Service or leak information. \n\nWorkaround\n==========\n\nA number of mitigating factors for CVE-2015-7547 have been identified. \nPlease review the upstream advisory and references below. \n\nResolution\n==========\n\nAll GNU C Library users should upgrade to the latest version:\n\n  # emerge --sync\n  # emerge --ask --oneshot --verbose \"\u003e=sys-libs/glibc-2.21-r2\"\n\nIt is important to ensure that no running process uses the old glibc\nanymore. The easiest way to achieve that is by rebooting the machine\nafter updating the sys-libs/glibc package. \n\nNote: Should you run into compilation failures while updating, please\nsee bug 574948. \n\nReferences\n==========\n\n[  1 ] CVE-2013-7423\n       http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-7423\n[  2 ] CVE-2014-0475\n       http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-0475\n[  3 ] CVE-2014-0475\n       http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-0475\n[  4 ] CVE-2014-5119\n       http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-5119\n[  5 ] CVE-2014-6040\n       http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-6040\n[  6 ] CVE-2014-7817\n       http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-7817\n[  7 ] CVE-2014-8121\n       http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-8121\n[  8 ] CVE-2014-9402\n       http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-9402\n[  9 ] CVE-2015-1472\n       http://nvd.nist.gov/nvd.cfm?cvename=CVE-2015-1472\n[ 10 ] CVE-2015-1781\n       http://nvd.nist.gov/nvd.cfm?cvename=CVE-2015-1781\n[ 11 ] CVE-2015-7547\n       http://nvd.nist.gov/nvd.cfm?cvename=CVE-2015-7547\n[ 12 ] CVE-2015-8776\n       http://nvd.nist.gov/nvd.cfm?cvename=CVE-2015-8776\n[ 13 ] CVE-2015-8778\n       http://nvd.nist.gov/nvd.cfm?cvename=CVE-2015-8778\n[ 14 ] CVE-2015-8779\n       http://nvd.nist.gov/nvd.cfm?cvename=CVE-2015-8779\n[ 15 ] Google Online Security Blog: \"CVE-2015-7547: glibc getaddrinfo\n       stack-based buffer overflow\"\n\nhttps://googleonlinesecurity.blogspot.de/2016/02/cve-2015-7547-glibc-geta=\nddrinfo-stack.html\n\nAvailability\n============\n\nThis GLSA and any updates to it are available for viewing at\nthe Gentoo Security Website:\n\n https://security.gentoo.org/glsa/201602-02\n\nConcerns?\n=========\n\nSecurity is a primary focus of Gentoo Linux and ensuring the\nconfidentiality and security of our users\u0027 machines is of utmost\nimportance to us.

A thorough security review should be performed by\nsecurity professionals to identify further potential security issues. \n\n\nVulnerability overview/description:\n-----------------------------------\n1) Authenticated Command Injection (CVE-2021-39279)\nAn authenticated command injection vulnerability can be triggered by issuing a\nGET request to the \"/forms/web_importTFTP\" CGI program which is available on\nthe web interface. An attacker can abuse this vulnerability to compromise the\noperating system of the device. This issue was found by emulating the firmware\nof the device. \n\n2) Reflected Cross-Site Scripting via Manipulated Config-File (CVE-2021-39278)\nVia a crafted config-file, a reflected cross-site scripting vulnerability can\nbe exploited in the context of the victim\u0027s browser. This config-file can be\nuploaded to the device via the \"Config Import Export\" tab in the main menu. \n\n3) Known GNU glibc Vulnerabilities (CVE-2015-0235)\nThe used GNU glibc in version 2.9 is outdated and contains multiple known\nvulnerabilities. One of the discovered vulnerabilities (CVE-2015-0235,\ngethostbyname \"GHOST\" buffer overflow) was verified by using the MEDUSA\nscalable firmware runtime. \n\n4) Multiple Outdated Software Components\nMultiple outdated software components containing vulnerabilities were found by\nthe IoT Inspector. \n\nThe vulnerabilities 1), 2) and 3) were manually verified on an emulated device\nby using the MEDUSA scalable firmware runtime. \n\nProof of concept:\n-----------------\n1) Authenticated Command Injection (CVE-2021-39279)\nThe vulnerability can be triggered by navigating in the web interface to the\ntab:\n\n\"Main Menu\"-\u003e\"Maintenance\"-\u003e\"Config Import Export\"\n\nThe \"TFTP Import\" menu is prone to command injection via all parameters. To\nexploit the vulnerability, an IP address, a configuration path and a filename\nmust be set. \nIf the filename is used to trigger the exploit, the payload in the interceptor\nproxy would be:\n\nhttp://192.168.1.1/forms/web_importTFTP?servIP=192.168.1.1\u0026configPath=/\u0026fileName=name|`ping localhost -c 100`\n\n\n2) Reflected Cross-Site Scripting via Manipulated Config-File (CVE-2021-39278)\nThe vulnerability can be triggered by navigating in the web interface to the\ntab:\n\n\"Main Menu\"-\u003e\"Maintenance\"-\u003e\"Config Import Export\"\n\nThe \"Config Import\" menu is prone to reflected cross-site scripting via the\nupload of config files. Example of malicious config file:\n-------------------------------------------------------------------------------\n[board]\ndeviceName=\"WAC-2004_0000\u003c/span\u003e\u003cscript\u003ealert(document.cookie)\u003c/script\u003e\"\ndeviceLocation=\"\"\n[..]\n-------------------------------------------------------------------------------\nUploading such a crafted file triggers cross-site scripting as the erroneous\nvalue is displayed without filtering characters. \n\n\n3) Known GNU glibc Vulnerabilities (CVE-2015-0235)\nGNU glibc version 2.9 contains multiple CVEs like:\nCVE-2016-1234, CVE-2015-7547, CVE-2013-7423, CVE-2013-1914, and more. \n\nThe gethostbyname buffer overflow vulnerability (GHOST) was checked with the\nhelp of the exploit code from https://seclists.org/oss-sec/2015/q1/274. It was\ncompiled and executed on the emulated device to test the system. \n\n\n4) Multiple Outdated Software Components\nThe IoT Inspector recognized multiple outdated software components with known\nvulnerabilities:\n\nBusyBox         1.18.5   06/2011\nDropbear SSH    2011.54  11/2011\nGNU glibc       2.9      02/2009\nLinux Kernel    2.6.27   10/2008\nOpenSSL         0.9.7g   04/2005\nOnly found in the program \"iw_director\"\nOpenSSL         1.0.0    03/2010\n\n\nVulnerable / tested versions:\n-----------------------------\nThe following firmware versions for various devices have been identified\nto be vulnerable:\n* WAC-2004               / 1.7\n* WAC-1001               / 2.1\n* WAC-1001-T             / 2.1\n* OnCell G3470A-LTE-EU   / 1.7\n* OnCell G3470A-LTE-EU-T / 1.7\n* TAP-323-EU-CT-T        / 1.3\n* TAP-323-US-CT-T        / 1.3\n* TAP-323-JP-CT-T        / 1.3\n* WDR-3124A-EU           / 2.3\n* WDR-3124A-EU-T         / 2.3\n* WDR-3124A-US           / 2.3\n* WDR-3124A-US-T         / 2.3\n\n\nVendor contact timeline:\n------------------------\n2020-10-09: Contacting vendor through moxa.csrt@moxa.com. \n2020-10-12: Contact sends PGP key for encrypted communication and asks for the\n             detailed advisory.
