Vulnerability from variot

This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of TP-Link TL-WR940N 3.20.1 Build 200316 Rel.34392n (5553) routers. Authentication is required to exploit this vulnerability. The specific flaw exists within the httpd service, which listens on TCP port 80 by default. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-13992. TP-LINK Technologies of TL-WR940N A stack-based buffer overflow vulnerability exists in the firmware.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state
