CVE-2016-5649: Netgear DGN2200 and DGND3700 disclose the administrator password

CriticalCVSS 9.8 · v3.0—Proof of concept No fix recorded

Noroxi assessment

Priority: Plan (action score 46/100)

  • A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
  • Public proof-of-concept code exists (Exploit-DB / GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 23.5% (FIRST EPSS); higher than 97.8% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.

Add it to your regular patch cycle. Update when a fix is released; follow the vendor's advisory.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

A vulnerability is in the 'BSW_cxttongr.htm' page of the Netgear DGN2200, version DGN2200-V1.0.0.50_7.0.50, and DGND3700, version DGND3700-V1.0.0.17_1.0.17, which can allow a remote attacker to access this page without any authentication. When processed, it exposes the admin password in clear text before it gets redirected to absw_vfysucc.cgia. An attacker can use this password to gain administrator access to the targeted router's web interface.
