Submit #643434: Wavlink WL-WN578W2 M78W2_V221110 Command Injection
| Title | Wavlink WL-WN578W2 M78W2_V221110 Command Injection |
|---|---|
| Description | A critical unauthenticated command injection vulnerability (with filter bypass) exists in /cgi-bin/adm.cgi of WAVLINK WL-WN578W2 (firmware M78W2_V221110). Attackers can directly access the wizard_rep.shtml page without login, then exploit the weak input filter (only blocks 2 characters: |, `) to bypass restrictions. By injecting arbitrary system commands via the sel_EncrypTyp parameter, attackers can execute root-level commands and fully compromise the device—no authentication required. |
