Name of the Vulnerable Software and Affected Versions FUXA versions prior to 1.2.11

Description FUXA is a web-based Process Visualization software. A flaw in the path sanitization logic allows an authenticated attacker with administrative privileges to bypass directory traversal protections. Utilizing nested traversal sequences (e.g., ....//), an attacker can write arbitrary files to the server filesystem, including sensitive directories like runtime/scripts. This can lead to Remote Code Execution (RCE) when the server reloads the malicious scripts. The vulnerability is related to insufficient input validation when handling file paths.

Recommendations Update to version 1.2.11 or later.
