Vulnerability Title
Termix Vulnerable to Arbitrary Command Execution via Session Hijacking
Source: NVD (National Vulnerability Database)
Vulnerability Description
Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. Prior to version 2.3.2, the File Manager functionality in Termix contains a critical Broken Access Control vulnerability due to improper validation of the sessionId parameter. The backend trusts a client-controlled identifier without verifying that it belongs to the authenticated user. This allows an attacker to manipulate the value and access active File Manager sessions belonging to other users. Since these sessions are tied to SSH connections to remote VPS instances, exploitation allows unauthorized interaction with another user's remote filesystem. Because the File Manager exposes functionality such as file reading, writing, uploading, and execution, this vulnerability enables direct command execution on another user's VPS (RCE). Version 2.3.2 patches the issue.

Vulnerability Description
Termix是Karmaa个人开发者的一个服务器管理平台。 Termix 2.3.2之前版本存在安全漏洞，该漏洞源于文件管理器功能对sessionId参数验证不当，信任客户端控制的标识符而未验证其属于经过身份验证的用户，可能导致攻击者操纵该值并访问其他用户的活跃文件管理器会话，实现与另一个用户远程文件系统的未授权交互，导致直接命令执行。
