Description
A vulnerability was determined in Technostrobe HI-LED-WR120-G2 5.5.0.1R6.03.30. The affected element is the function index_config of the file /LoginCB. This manipulation causes improper authentication. It is possible to initiate the attack remotely. The exploit has been publicly disclosed and may be utilized. The vendor was contacted early about this disclosure but did not respond in any way.
An authentication bypass vulnerability has been identified in the Technostrobe HI-LED-WR120-G2 obstruction lighting controller, specifically in version 5.5.0.1R6.03.30. The vulnerability arises from client-side authentication enforcement, allowing attackers to manipulate HTTP responses and gain unauthorized access to protected resources. This issue can be exploited remotely without any authentication requirements.
It is recommended to move authentication enforcement to the server side, issue signed 'HttpOnly' session cookies at login, and ensure that every protected endpoint independently checks session validity. Additionally, applying a defense-in-depth strategy can help mitigate the risks.
