| Titolo | TOTOLINK N600R firmware V4.3.0cu.7866_B20220506 Buffer Overflow |
|---|
| Descrizione | A buffer overflow vulnerability has been identified in the TOTOLINK N600R router firmware that allows remote attackers to potentially execute arbitrary code or cause denial of service through malformed HTTP requests. The vulnerable code is within the setWiFiBasicConfig function in cstecgi.cgi. It extracts the `wepkey` parameter into `v13` and passes it into the `strcpy` function. When `wepkey` is specified with excessive data, a buffer overflow occurs. |
