Dell Trusted Device, versions prior to 7.0.3.0, contain an Improper Link Resolution Before File Access (Link Following) vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Elevation of privileges.

Weakness

The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.

Affected Software

Name Vendor Start Version End Version
Trusted_device_agent Dell * 7.0.3.0 (excluding)

Potential Mitigations

  • Follow the principle of least privilege when assigning access rights to entities in a software system.
  • Denying access to a file can prevent an attacker from replacing that file with a link to a sensitive file. Ensure good compartmentalization in the system to provide protected areas that can be trusted.
