AI risk analysis

Summary: The flaw allows any authenticated user to execute arbitrary code as root by manipulating plugin installation and uninstallation tasks, leading to full host compromise.
Exploitability: Exploitation is relatively straightforward given an authenticated user with access to the /api/core/tasks/start endpoint. Precondition is a user with basic authentication credentials.
Blast radius: If exploited, the impact is severe, as it results in full host compromise and potential root code execution.
Detection: No reliable host or network indicator is derivable from the published description.
Prioritized remediation: Upgrade to version 2.2.16 or later.

NVD description

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.
