  "details": "### Summary\n**Vulnerable Version:** Yeswiki  \u003c v4.5.4\n**Category:** Injection\n**CWE: 79:** Improper Neutralization of Input During Web Page Generation (CWE-79)\n**CVSS:** 5.3 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N)\n**Vulnerable Endpoint:** `/?BazaR/bazariframe`\n**Vulnerable Parameter:** `template`\n**Payload:** `\u003cscript\u003ealert(1)\u003c/script\u003e`\n\n### Details\nReflected Cross-Site Scripting (XSS) attacks are a type of injection, in which malicious scripts are injected into otherwise benign and trusted websites. XSS attacks occur when an attacker uses a web application to send malicious code, generally in the form of a browser-side script, to a different end user. Flaws that allow these attacks to succeed are quite widespread and occur anywhere a web application uses input from a user within the output it generates without validating or encoding it.\n\n### PoC\n1. Visit the endpoint as mentioned below and see that an alert box pops up:\n   **URL with Payload:** `https://yeswiki.net/?BazaR/bazariframe\u0026id=2\u0026template=%3cscript%3ealert(1)%3c%2fscript%3e`\n\n### Impact\nAn attacker can use a reflected cross-site scripting attack to steal cookies from an authenticated user by having them click on a malicious link. Stolen cookies allow the attacker to take over the user\u2019s session. This vulnerability may also allow attackers to deface the website or embed malicious content.",
