AI risk analysis

Summary: The flaw allows an authenticated administrator to execute arbitrary commands via shell interpolation, leading to remote code execution.
Exploitability: Exploitation is relatively straightforward given an authenticated administrator account. Precondition is access to the Termix backend API.
Blast radius: If exploited, it could lead to full compromise of Termix databases, process secrets, and network reachability.
Detection: No reliable host or network indicator is derivable from the published description.
Prioritized remediation: Upgrade to Termix version 2.5.1 or later.

NVD description

Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. From 2.4.1 until 2.5.1, an authenticated Termix administrator can store attacker-controlled domain and email values through PATCH /users/acme-ssl-settings and trigger their interpolation into a certbot shell command through POST /users/acme-ssl-request. In src/backend/database/routes/acme-ssl-routes.ts, child_process.execSync invokes /bin/sh -c with those values only wrapped in double quotes, so shell metacharacters can execute arbitrary operating-system commands as the Termix backend process. Both HTTP webroot and DNS Cloudflare challenge modes are affected, and compromise exposes Termix databases, process secrets, stored credentials, and network reachability. This issue is fixed in version 2.5.1.
