|---|
| Mô tả | A stack-based buffer overflow vulnerability exists in the R7WebsSecurityHandler function (0x0043dea0) in /bin/httpd of Tenda AC10 V4 firmware V16.03.10.10. The password parameter of a POST request to /login/Auth is copied via strcpy() into a 128-byte stack buffer without bounds checking. The saved return address is located 1448 bytes from the buffer start. No authentication is required, allowing a remote attacker to overwrite the saved return address and achieve arbitrary code execution. The binary lacks stack canaries, PIE, and ASLR. |
