| Title | Wavlink WL-NU516U1-A M16U1_V240425 Command Injection |
|---|
| Description | Wavlink WL-NU516U1 firmware M16U1_V240425 contains a command injection vulnerability in /cgi-bin/wireless.cgi. When the page parameter is set to DeleteMac, the function sub_402D1C reads the b_delete_al_mac POST parameter via the URL decode function sub_405EA8. The decoded value is concatenated into a shell command using sprintf("/etc/lighttpd/www/cgi-bin/del_mac.sh y%s y%s y%s y%s &", delete_list, delete_al_mac, b_delete_list, b_delete_al_mac) and executed via the system() wrapper sub_405314. No input filter is applied in the DeleteMac handler. The $(cmd) command substitution syntax allows arbitrary command execution. |
