CVE-2016-5649

49
FAUCET Score

CVE-2016-5649 describes an authentication bypass vulnerability in the Netgear DGN2200 (firmware DGN2200-V1.0.0.50_7.0.50) and DGND3700 (firmware DGND3700-V1.0.0.17_1.0.17) routers. A remote attacker can access the 'BSW_cxttongr.htm' page without authentication, which then exposes the administrator password in clear text. This critical vulnerability (CVSS 9.8) allows for complete compromise of the router's web interface, as an attacker can gain full administrative access. While there is no evidence of active exploitation or Metasploit modules, Nuclei templates exist for detecting this flaw, and its EPSS score indicates a higher than average exploitability probability. Despite its severity, there is minimal community discussion or media coverage.
