Chamilo: Account Takeover via Stored XSS in Course Description

Chamilo is a learning management system. Prior to version 1.11.34, there is a stored cross-site scripting (XSS) vulnerability. By injecting malicious JavaScript into the course description field, an attacker with a low-privileged account (e.g., trainer) can execute arbitrary JavaScript code in the context of any other user viewing the course information page, including administrators. This allows an attacker to exfiltrate sensitive session cookies or tokens, resulting in account takeover (ATO) of higher-privileged users. This issue has been patched in version 1.11.34.

Chamilo 跨站脚本漏洞

Chamilo是Chamilo开源的一个学习管理系统。 Chamilo 1.11.34之前版本存在跨站脚本漏洞，该漏洞源于课程描述字段输入验证不足，可能导致存储型跨站脚本攻击，进而使低权限用户在其他用户浏览器中执行任意JavaScript，导致账户接管。
