CWEhttps://cwe.mitre.org/data/definitions/59.html

Red Hat Cluster Project 2.x allows local users to modify or overwrite arbitrary files via symlink attacks on files in /tmp, involving unspecified components in Resource Group Manager (aka rgmanager) before 2.03.09-1, gfs2-utils before 2.03.09-1, and CMAN - The Cluster Manager before 2.03.09-1 on Fedora 9.

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.

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.
