VAR-201906-0412
Vulnerability from variot - Updated: 2023-12-18 13:02TP-Link TL-WR940N is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the ipAddrDispose function. By sending specially crafted ICMP echo request packets, a remote authenticated attacker could overflow a buffer and execute arbitrary code on the system with elevated privileges. TP-Link TL-WR940N Contains a buffer error vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. The TP-Link TL-WR940N and the TP-Link TL-WR941ND are both wireless routers from China Unicom (TP-Link).
A buffer overflow vulnerability exists in TP-LINK TL-WR940N and TL-WR941ND. This vulnerability is caused when the network system or product performs operations on memory and does not correctly verify the data boundary, resulting in an error being performed to other associated memory locations. Read and write operations that an attacker can exploit to cause a buffer overflow or heap overflow
