Summary
Ajenti up to version 2.2.13 has a clickjacking vulnerability in the login and administrative UI. Missing X-Frame-Options and Content-Security-Policy frame-ancestors headers in HTTP responses allow the page to be embedded in an iframe.
Risk Assessment
An attacker can trick an administrator into performing unintended actions (e.g., changing configuration) by embedding the Ajenti panel on a malicious site, leading to system compromise.
Recommendation
Update Ajenti to the latest patched version. If unavailable, manually add X-Frame-Options: DENY or Content-Security-Policy: frame-ancestors 'none' headers in the proxy server configuration.
Other vulnerabilities in Ajenti
See all- CVE-2026-79920Critical
Ajenti is a Linux & BSD modular server admin panel. Prior to version 2.2.16, any authenticated user can call /api/core/tasks/start to enqueue InstallPlugin, UnInstallPlugin, or UpgradeAll from plugins/plugins/tasks.py without plugin-management authorization. InstallPlugin and UnInstallPlugin construct a pip package specification from unvalidated name and version fields, and the task worker invokes pip while running as root. A low-privileged user can therefore select or manipulate a package installed with root privileges and can install, remove, or upgrade plugins without administrative permission, resulting in root code execution and full host compromise. This issue is fixed in version 2.2.16.
- CVE-2020-37002Critical
Ajenti version 2.1.36 contains a post-authenticated remote command execution vulnerability that allows remote attackers to execute arbitrary commands after successful login. Attackers can leverage the /api/terminal/create endpoint to send a netcat reverse shell payload targeting a specified IP and port.
- CVE-2026-35175Medium
Ajenti before version 2.2.15 allows an authenticated user (using the auth_users plugin) to install a custom package even if not a superuser. This vulnerability is fixed in version 2.2.15.
Original NVD description (English source)
ajenti through v2.2.13 has a clickjacking weakness in the browser-facing login and administrative UI. In ajenti-core/aj/http.py, the core HTTP response path initializes an empty header list, forwards handler-added headers verbatim, and finalizes responses through WSGI start_response() without adding anti-framing protections such as X-Frame-Options or a Content-Security-Policy frame-ancestors restriction.
