CVE-2024-3272: D-Link DNS-320L/DNS-325/DNS-327L/DNS-340L HTTP GET Request nas_sharing.cgi hard-coded credentials

Noroxi assessment

Priority: Now (action score 98/100)

  • CISA has confirmed exploitation in the wild (Apr 11, 2024). Remediation deadline for US federal agencies: May 2, 2024.
  • A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
  • Probability of exploitation in the next 30 days: 98.1% (FIRST EPSS); higher than 99.9% 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 CISA the attack is automatable: targets can be found by mass scanning.
  • 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.

Primary sources: NVD · CVE.org · CISA KEV · FIRST EPSS

** UNSUPPORTED WHEN ASSIGNED ** A vulnerability, which was classified as very critical, has been found in D-Link DNS-320L, DNS-325, DNS-327L and DNS-340L up to 20240403. This issue affects some unknown processing of the file /cgi-bin/nas_sharing.cgi of the component HTTP GET Request Handler. The manipulation of the argument user with the input messagebus leads to hard-coded credentials. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The associated identifier of this vulnerability is VDB-259283. NOTE: This vulnerability only affects products that are no longer supported by the maintainer. NOTE: Vendor was contacted early and confirmed immediately that the product is end-of-life. It should be retired and replaced.

Root cause

For convenience in support or manufacturing, an account that is identical on every device is embedded in the software. Credentials learned from one device work on all of them.
