CVE-2023-33559Network attack vector

Authenticated code execution via unchecked language inclusion

Published Oct 26, 2023 · Updated Sep 10, 2024

Local file inclusion in OcoMon before 4.0.1 allows remote authenticated users to execute arbitrary PHP code through the lang parameter. The vulnerable request path uses the attacker-controlled lang value to select a PHP file for inclusion without constraining it to trusted language files. A valid low-privilege session and an attacker-supplied PHP file reachable by the server are required, after which code runs with web-server privileges.
