PowerProtect Data Domain Feature Release: Authentication Bypass by Spoofing
CVE-2025-36594 is a critical-severity authentication bypass by spoofing vulnerability in PowerProtect Data Domain Feature Release from Dell, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected PowerProtect Data Domain Feature Release versions: 7.7.1.0 through 8.3.0.15. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.56% chance of exploitation within 30 days, which is low compared with other CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update Data Domain Operating System to 7.10.1.70 or 7.13.1.30 or 8.3.1.0, whichever matches your release line, or a later version.
- Read the advisory on dell.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
