Centrify Deployment Manager 2.1.0.283, as distributed in Centrify Suite before 2012.5, allows local users to (1) overwrite arbitrary files via a symlink attack on the adcheckDMoutput temporary file, or (2) overwrite arbitrary files and consequently gain privileges via a symlink attack on the centrify.cmd.0 temporary file.

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
Centrify_deployment_manager Centrify 2.1.0.283 (including) 2.1.0.283 (including)
Centrify_suite Centrify * 2012 (including)

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.
