Wavlink WL-WN530BE2-A Login Processing api.cgi sub_12580 os command injection
A vulnerability has been found in Wavlink WL-WN530BE2-A up to M30BE2_V250604. The affected element is the function sub_12580 of the file api.cgi of the component Login Processing. The manipulation of the argument REMOTE_ADDR leads to os command injection. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. Upgrading to version 2026-09-24-841a51c6d5_tclinux.bin is sufficient to fix this issue. You should upgrade the affected component. The vendor confirms: "We confirm the finding, and it has already been addressed. In the current firmware the api=info&client=app handler no longer builds a shell command: the login script is now invoked through an argument vector (execvp) instead of system(), and the client address is length-limited and null-checked."
