Submit #665614: Tenda Shenzhen Jixiang Tengda Technology Co., Ltd. Router CH22 V1.0.0.1 V1.0.0.1 Buffer Overflowinfo

TitleTenda Shenzhen Jixiang Tengda Technology Co., Ltd. Router CH22 V1.0.0.1 V1.0.0.1 Buffer Overflow
DescriptionDuring the security assessment of the application, a critical buffer overflow vulnerability was discovered in the goform/GstDhcpSetSer endpoint. The issue originates from the formWrlExtraGet() function, which copies user-supplied input s into a fixed-size buffer v9 using strncpy without adequate bounds checking. If the input exceeds 32 bytes, it can overwrite adjacent memory, potentially leading to application crashes, memory corruption, or arbitrary code execution. This vulnerability poses a significant risk to system stability, data confidentiality, and overall network security, requiring immediate mitigation to prevent exploitation.
