| Title | Wavlink WL-WN578W2 M78W2_V221110 Command Injection |
|---|
| Description | A critical unauthenticated command injection vulnerability exists in /cgi-bin/firewall.cgi of WAVLINK WL-WN578W2 (firmware M78W2_V221110). The endpoint lacks authentication checks, and the pingFrmWANFilterEnabled，blockSynFloodEnabled，blockPortScanEnabled，remoteManagementEnabled parameter (processed in the sub_401C5C function, which handles firewall-related logic) is not sanitized. Unauthenticated attackers can send POST requests with injected commands to take full control of the device. |
