A vulnerability exists in the Technostrobe HI-LED-WR120-G2 obstruction lighting controller, specifically in version 5.5.0.1R6.03.30. The issue arises in the FsBrowseClean component, where the deletefile function lacks proper authorization checks. This vulnerability allows for unauthenticated deletion of arbitrary files on the device, including critical system configuration files. The flaw can be exploited remotely, and a public proof-of-concept is available.
To address this vulnerability, it is recommended to implement authentication for all AJAX handlers, restrict deletable paths to specific directories, canonicalize path parameters to prevent traversal attacks, and log all file deletion actions.
