CVE-2022-35525Public exploitNetwork attack vector

Unauthenticated command injection via led_switch

Published Aug 9, 2022 · Updated Aug 3, 2024

Command injection in WAVLINK WN572HP3, WN533A8, WN530H4, WN535G3, and WN531P3 allows remote attackers to execute commands through the router web interface. The adm.cgi handler passes the led_switch parameter to the /ledonoff.shtml LED-control page without filtering, allowing attacker-controlled command input to reach execution. The interface is reachable over the network without authentication, so a crafted request can compromise confidentiality, integrity, and availability of an exposed router.
