Authenticated command execution via unfiltered QoS parameters
Published Aug 9, 2022 · Updated Aug 3, 2024
Command injection in WAVLINK WN572HP3, WN533A8, WN530H4, WN535G3, and WN531P3 allows remote authenticated users to execute commands. The qos.cgi handler passes attacker-controlled cli_list and cli_num POST values without filtering shell metacharacters such as semicolons. Successful exploitation runs attacker-chosen commands on the router, but the disclosed path requires a valid web-management login.
