PowerStore: Exposure of Resource to Wrong Sphere
CVE-2022-26869 is a critical-severity exposure of resource to wrong sphere vulnerability in PowerStore 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. The record lists version 2.0.0.x, 2.0.1.x, and 2.1.0.x as the first without the flaw, so updating PowerStore to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 2.06% chance of exploitation within 30 days, higher than 82% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update PowerStore to 2.0.0.x, 2.0.1.x, and 2.1.0.x or a later version.
- Update Powerstoreos to 2.1.1.0 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.
