根据网页截图，关于漏洞的关键信息如下： TARGET Device: Tenda AC8 Firmware Version: V16.03.33.05 Vendor Website: https://www.tendacn.com/ Firmware Reference: AC8v4.0 Firmware - Tenda Global (English) BUG TYPE Vulnerability Type: Stack-Based Buffer Overflow Vulnerability Cause: Improper input validation in the router's HTTP service interface. Vulnerability Description Summary: A buffer overflow vulnerability exists in the interface in the embedded service, which fails to properly validate user-supplied input in the parameter. Impact: An attacker can exploit this vulnerability by sending a specially crafted HTTP request with an overly long value, potentially leading to a denial-of-service condition. Vulnerability Analysis Source Code: The vulnerability is observed in the binary within the function . Issue in Code: - The parameter is user-controlled with no effective validation. - The code uses to parse the input, leading to a potential stack-based buffer overflow condition. Proof-of-Concept (POC) Code Example: Expected Result Outcome: Running the exploit produces a Segmentation Fault, confirming the presence of a serious memory safety issue. Conclusion The Tenda AC8 router running firmware version V16.03.33.05 is vulnerable to a stack-based buffer overflow due to improper input validation in the service. This vulnerability can be exploited by sending a crafted HTTP request with a long parameter, potentially causing a denial-of-service condition or arbitrary code execution.
