CVE-2022-45100 is a critical-severity improper certificate validation vulnerability in PowerScale OneFS 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 PowerScale OneFS versions: 8.2.x through 9.3.x. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.52% 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 Emc Powerscale Onefs to 9.1.0.25 or 9.2.1.18 or 9.3.0.7 or 9.4.0.9, 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.

Official description
Dell PowerScale OneFS, versions 8.2.x-9.3.x, contains an Improper Certificate Validation vulnerability. An remote unauthenticated attacker could potentially exploit this vulnerability, leading to a full compromise of the system.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Improper Certificate Validation
The product does not validate, or incorrectly validates, a certificate.
How developers prevent this class of flaw
- Certificates should be carefully managed and checked to assure that data are encrypted with the intended owner's public key.
- If certificate pinning is being used, ensure that all relevant properties of the certificate are fully validated before the certificate is pinned, including the hostname.
