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.

Ajenti is a Linux and BSD modular server admin panel. Prior to version 2.2.13, an unauthenticated user could gain access to a server to execute arbitrary code on this server. This is fixed in the version 2.2.13.

Ajenti 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.

Impact

An authenticated user (using the authusers plugin authentication method) could install a custom package even if this user is not superuser.

Patches

This is fixed in the version 2.2.15. Users should upgrade to this version as soon as possible.

Multiple cross-site scripting (XSS) vulnerabilities in the responderror function in routing.py in Eugene Pankov Ajenti before 1.2.21.7 allow remote attackers to inject arbitrary web script or HTML via the PATHINFO to (1) resources.js or (2) resources.css in ajenti:static/, related to the traceback page.

Cross-site scripting (XSS) vulnerability in plugins/main/content/js/ajenti.coffee in Ajenti before 1.2.15 allows remote authenticated users to inject arbitrary web script or HTML via the command field in the Cron functionality.
