CVE-2020-10923

77
FAUCET Score

CVE-2020-10923 is an authentication bypass vulnerability affecting NETGEAR R6700 V1.0.4.84_10.0.58 routers, specifically within the UPnP service on TCP port 5000. This high-severity flaw (CVSS 8.8) allows unauthenticated, network-adjacent attackers to bypass authentication using a crafted UPnP message, potentially leading to arbitrary code execution as root when chained with other vulnerabilities. While not actively exploited in the wild (KEV: No), a Metasploit module exists for a related password reset vulnerability, and there is minimal community discussion or media coverage.
