What is CVE-2021-45995?

Tenda routers G1 and G3, running firmware version 15.11.0.17(9502)_CN, have been identified to contain a stack overflow vulnerability in the formSetStaticRoute function. This flaw allows attackers to exploit specific parameters related to static routing—namely staticRouteNet, staticRouteMask, and staticRouteGateway—to trigger a Denial of Service (DoS) attack. By manipulating these parameters, malicious individuals can disrupt the normal operation of the routers, thereby impacting network connectivity and performance. Organizations utilizing these affected models should prioritize mitigation strategies to defend against potential exploitation.
