Observium Professional, Enterprise & Community 20.8.10631 contains a directory traversal and local file inclusion vulnerability. The application allows unrestricted loading of any file with an inc.php extension via crafted requests to /settings/?format=../, which are processed by pages/settings.inc.php. This allows attackers to traverse directories and include arbitrary inc.php files, potentially leading to remote code execution if attacker-controlled files are included.
