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.

Weakness

During installation, installed file permissions are set to allow anyone to modify those files.

Affected Software

Name Vendor Start Version End Version
Emc_unity_operating_environment Dell * 5.0.4.0.5.012 (excluding)
Emc_unity_vsa_operating_environment Dell * 5.0.4.0.5.012 (excluding)
Emc_unity_xt_operating_environment Dell * 5.0.4.0.5.012 (excluding)

Potential Mitigations

  • Compartmentalize the system to have “safe” areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
  • Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
