| 제목 | Tenda FH451 v1.0.0.9 Stack-based Buffer Overflow |
|---|
| 설명 | The router model FH451V1.0.0.9, manufactured by Shenzhen Tenda Technology Co., Ltd., contains a binary stack-based buffer overflow vulnerability located within the function fromNatlimit. This function receives a parameter a1 via a POST request and extracts a variable named page from it. Subsequently, the function utilizes the sprintf function to copy the contents of the page variable into a buffer array of size 256 bytes without performing any bounds checking. An attacker can exploit this vulnerability to cause a denial of service (DoS) condition. Furthermore, this vulnerability can be leveraged to construct a Return-Oriented Programming (ROP) chain, enabling the attacker to overwrite the return address and achieve privilege escalation or remote code execution (RCE). |
