An issue was discovered in Observium Professional, Enterprise & Community 20.8.10631. It is vulnerable to directory traversal and local file inclusion due to the fact that there is an unrestricted possibility of loading any file with an inc.php extension. Inclusion of other files (even though limited to the mentioned extension) can lead to Remote Code Execution. This can occur via /device/device=345/?tab=routing&proto=../ URIs to device/routing.inc.php.

Exploit prediction

2.96% chance of exploitation in the next 30 days, higher than 87% of all scored CVEs (FIRST EPSS, 2026-11-08).
