CVE-2026-5573 Details
Description
A weakness has been identified in Technostrobe HI-LED-WR120-G2 5.5.0.1R6.03.30. This impacts an unknown function of the file /fs. Executing a manipulation of the argument cwd can lead to unrestricted upload. The attack can be launched remotely. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
A vulnerability allowing unrestricted file uploads has been identified in the Technostrobe HI-LED-WR120-G2 obstruction lighting controller, specifically in version 5.5.0.1R6.03.30. The issue arises from a lack of authentication and proper file validation in the '/fs' endpoint, which accepts any file type and writes to user-specified directories. This vulnerability could be exploited remotely, with the potential for uploaded files to be immediately accessible via HTTP.
To address this vulnerability, it is recommended to implement authentication checks for file uploads, restrict upload directories to a designated 'uploads' folder, allow only specific file types that are operationally necessary, and remove the '/fs' endpoint from production firmware if it is not in use.
