Description

FreePBX is an open source IP PBX. Prior to 16.0.22 and 17.0.5, the Dashboard module's getcontent AJAX handler includes PHP files based on user-supplied input without path sanitization. The $_REQUEST['rawname'] parameter is concatenated into an include() call with a .class.php suffix, allowing path traversal via ../ sequences to include arbitrary .class.php files from the filesystem. The included file's PHP code executes before the subsequent class instantiation error occurs. This vulnerability is fixed in 16.0.22 and 17.0.5.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability high.
