CVE intelligence and bounded remediation

CVE-2020-29489 — Dell EMC Unity, Unity XT, and UnityVSA versions prior to 5.0.4.0.5.012 contains a plain-text password storage vulnerability

Medium CVSS 6.7

Dell EMC Unity, Unity XT, and UnityVSA versions prior to 5.0.4.0.5.012 contains a plain-text password storage vulnerability. A user credentials (including the Unisphere admin privilege user) password is stored in a plain text in a system file. A local authenticated attacker with access to the system files may use the exposed password to gain access with the privileges of the compromised user.

Matched remediation archetype

Privilege escalation and unsafe privilege management

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map service accounts, operating-system identities, roles, capabilities, impersonation, set-user transitions, and administrative helper paths.
  • Determine whether untrusted users or lower-privilege processes can reach the affected transition or modify inputs it trusts.
  • Review file, socket, registry, device, job, container, and cloud-role permissions used before and after privilege changes.

Remediate safely

  • Apply the supported fix and redesign privileged operations as a minimal, authenticated, allowlisted interface.
  • Drop privileges before processing untrusted input, verify the drop succeeds, and remove unnecessary roles, capabilities, and write permissions.
  • Validate ownership and permissions at time of use and add explicit lower-to-higher privilege boundary tests.
