CVE-2025-43887: Dell PowerProtect Data Manager, version(s) 19.19 and 19.20, Hyper-V contain(s) an Incorrect Default Permissions vulnerability.

Noroxi assessment

Priority: Monitor (action score 31/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.10% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Dell PowerProtect Data Manager 19.21 build 11.

Low priority for now. Upgrade to Dell PowerProtect Data Manager 19.21 build 11 or later.
