| Título | Tenda AC10 V4 US_AC10V4.0si_V16.03.10.10_multi_TDE01 Stack-based Buffer Overflow |
|---|
| Descrição | Multiple stack-based buffer overflow vulnerabilities exist in the R7WebsSecurityHandler function (0x0043dea0) in /bin/httpd of Tenda AC10 V4 firmware V16.03.10.10. User-controlled input from websGetVar() flows into strcpy() at 0x0043f6d0 and 0x0043fba4, and into sprintf() at 0x0043f768 and 0x004404a4, without bounds checking. As a pre-authentication handler, all paths are reachable without credentials, allowing a remote attacker to corrupt the stack and achieve arbitrary code execution. |
