|---|
| Mô tả | Wavlink WL-NU516U1 firmware M16U1_V240425 contains a command injection vulnerability in /cgi-bin/wireless.cgi. When the page parameter is set to multi_ssid, the function sub_401D68 reads the SSID5G2 POST parameter via the URL decode function sub_405EA8. The decoded value is appended with "_Touch" and concatenated into shell commands using sprintf("set_bss.sh set 2 \"%s_Touch\" OPEN NONE Admin12345", ssid) and executed via system(). The input filter sub_4074A0 only blocks backtick and pipe characters, but the $(cmd) command substitution syntax is not filtered, allowing arbitrary command execution. |
