The Artica-Proxy administrative web application will deserialize arbitrary PHP objects supplied by unauthenticated users and subsequently enable code execution as the "www-data" user.

In Artica Pandora FMS 7.42, Web Admin users can execute arbitrary code by uploading a .php file via the Updater or Extension component. NOTE: The vendor reports that this is intended functionality

The Artica Proxy administrative web application will deserialize arbitrary PHP objects supplied by unauthenticated users and subsequently enable code execution as the "www-data" user. This issue was demonstrated on version 4.50 of the The Artica-Proxy administrative web application attempts to prevent local file inclusion. These protections can be bypassed and arbitrary file requests supplied by unauthenticated users will be returned according to the privileges of the "www-data" user.

Services that are running and bound to the loopback interface on the Artica Proxy are accessible through the proxy service. In particular, the "tailon" service is running, running as the root user, is bound to the loopback interface, and is listening on TCP port 7050. Security issues associated with exposing this network service are documented at gvalkov's 'tailon' GitHub repo. Using the tailon service, the contents of any file on the Artica Proxy can be viewed.

The "Rich Filemanager" feature of Artica Proxy provides a web-based interface for file management capabilities. When the feature is enabled, it does not require authentication by default, and runs as the root user.

Cron log backup files contain administrator session IDs. It is trivial for any attacker who can reach the Pandora FMS Console to scrape the cron logs directory for cron log backups. The contents of these log files can then be abused to authenticate to the application as an administrator. This issue affects Pandora FMS <= 772.
