CVE-2024-33788Public exploit

Authenticated arbitrary command execution via unfiltered WPS PIN

Published May 6, 2024 · Updated Aug 2, 2024

Command injection in Linksys E5600 Firmware 1.1.0.26 allows remote authenticated users to execute arbitrary commands via /API/info. The runtime.wpsProcess function appends the request's PinCode value directly to a wps_action.sh command and passes it to os.execute without filtering shell metacharacters. Exploitation requires an authenticated low-privilege session and adjacent-network access to the router management interface.
