CVE-2015-2051: The D-Link DIR-645 Wired/Wireless Router Rev.

Noroxi assessment

Priority: Now (action score 94/100)

  • CISA has confirmed exploitation in the wild (Feb 10, 2022). Remediation deadline for US federal agencies: Aug 10, 2022.
  • A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
  • Probability of exploitation in the next 30 days: 97.1% (FIRST EPSS); higher than 99.8% of all records.
  • Someone on the same network segment 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.

Patch today or shut off access. Until a fix is released, restrict access to the affected component and follow the vendor's advisory.
