OS Command Injection in Termix (CVE-2026-45750)
Summary
OS command injection in Termix (CVE-2026-45750). Successful exploitation can lead to full system takeover. Exploitable via GET /ssh/file_manager/ssh/resolvePath.
Original description
The description as published by the source.
Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. Prior to version 2.3.2, the GET /ssh/file_manager/ssh/resolvePath endpoint in the Termix File Manager component unsafely processes the path parameter and embeds it into a shell command executed over the active SSH session. Because the user-controlled value is placed inside double quotes and only double quotes are escaped, shell command substitution syntax such as $(...) is still interpreted by the remote shell. Version 2.3.2 fixes the issue.

Refs: see the GHSA / vendor advisory / patched release linked on this page.
OS command injection (CWE-78) exists in Termix. Attackers reach the vulnerable code path via GET /ssh/file_manager/ssh/resolvePath.
Check the vendor advisory for the affected versions of Termix. Attack surface: GET /ssh/file_manager/ssh/resolvePath.
Severity: Critical (CVSS 9.0/10). Successful exploitation can lead to full system takeover.
Update to the patched release per vendor advisory.
Until the patch is applied: disable the affected feature, apply WAF rules, or restrict access via network ACLs.
Search webserver/proxy logs for unusual GET /ssh/file_manager/ssh/resolvePath requests with malformed payloads or SQL meta-characters. Run grep -r 'Termix' . against your dependency files (package-lock.json, requirements.txt, go.sum) to find affected services.

1Identify exposure identify
grep -r 'Termix' . | grep -v node_modulesリポジトリと本番環境の依存ファイル (package-lock.json / requirements.txt / go.sum / Gemfile.lock 等) で
Termixを grep し、稼働しているサービス・バージョンを把握する。 -
2Hunt for indicators of compromise detect
grep 'GET /ssh/file_manager/ssh/resolvePath' /var/log/nginx/access.log | grep -E '(unusual_payload|sqli_pattern)'アクセスログで
GET /ssh/file_manager/ssh/resolvePathへの異常なリクエスト (不正な認証ヘッダ・SQLメタ文字)を過去 30〜90日分捜索。WAF/SIEM があれば該当パスのアラート発火履歴を確認。 -
3Post-deployment verification verify
Replay attack against GET /ssh/file_manager/ssh/resolvePath on staging to confirm patch closes the vectorパッチ適用後、ステージングで PoC または同等の悪用パターンを再現して脆弱性が閉じたことを確認。本番では Step 2 と同じログクエリでアラート再発が無いか継続監視。
