VAR-202103-0938

Vulnerability from variot - Updated: 2024-11-23 22:37

This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of NETGEAR R6400 and R6700 firmware version 1.0.4.98 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the upnpd service, which listens on UDP port 1900 by default. A crafted MX header field in an SSDP message can trigger an overflow of a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-11851. NETGEAR R6400 and R6700 A stack-based buffer overflow vulnerability exists in the firmware. Zero Day Initiative To this vulnerability ZDI-CAN-11851 Was numbered.Information is obtained, information is tampered with, and service is disrupted (DoS) It may be put into a state
