PowerProtect Data Domain with Data Domain…: Incorrect Implementation of Authentication Algorithm

CVE-2025-43727 is a high-severity incorrect implementation of authentication algorithm vulnerability in PowerProtect Data Domain with Data Domain Operating System (DD OS) of Feature Release from Dell, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 8.3.0.10 as the first without the flaw, so updating PowerProtect Data Domain with Data Domain Operating System (DD OS) of Feature Release to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.36% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update PowerProtect Data Domain with Data Domain Operating System (DD OS) of Feature Release to 8.3.0.10 or a later version.
  2. Update PowerProtect Data Domain with Data Domain Operating System (DD OS) LTS2024 to 7.13.1.30 or a later version.
  3. Update PowerProtect Data Domain with Data Domain Operating System (DD OS) LTS2023 to 7.10.1.60 or a later version.
  4. Read the advisory on dell.com for workarounds and exact fixed builds.
  5. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

Dell PowerProtect Data Domain with Data Domain Operating System (DD OS) of Feature Release versions 7.7.1.0 through 8.1.0.10, LTS2024 release Versions 7.13.1.0 through 7.13.1.25, LTS 2023 release versions 7.10.1.0 through 7.10.1.50, contain an incorrect Implementation of Authentication Algorithm vulnerability in the RestAPI. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to Unauthorized access.

Source: the CVE record as published by its numbering authority, via NVD and CVE.org.

The underlying weakness: Incorrect Implementation of Authentication Algorithm

The requirements for the product dictate the use of an established authentication algorithm, but the implementation of the algorithm is incorrect.
