Cyber Recovery: Improper Authentication
CVE-2022-34372 is a critical-severity improper authentication vulnerability in Cyber Recovery from Dell, with a CVSS 3.1 base score of 9.1 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 19.11 as the first without the flaw, so updating Cyber Recovery to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 1.27% chance of exploitation within 30 days, higher than 70% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update Cyber Recovery to 19.11 or a later version.
- Update Powerprotect Cyber Recovery to 19.11.0.2 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.
