Puppet 0.24.x before 0.24.9 and 0.25.x before 0.25.2 allows local users to overwrite arbitrary files via a symlink attack on the (1) /tmp/daemonout, (2) /tmp/puppetdoc.txt, (3) /tmp/puppetdoc.tex, or (4) /tmp/puppetdoc.aux 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.

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.
