Vulnerability CVE-2023-34096
Published: 2023-06-08

Description:
Thruk is a multibackend monitoring webinterface which currently supports Naemon, Icinga, Shinken and Nagios as backends. In versions 3.06 and prior, the file `panorama.pm` is vulnerable to a Path Traversal vulnerability which allows an attacker to upload a file to any folder which has write permissions on the affected system. The parameter location is not filtered, validated or sanitized and it accepts any kind of characters. For a path traversal attack, the only characters required were the dot (`.`) and the slash (`/`). A fix is available in version 3.06.2.
