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

Fabric before 1.1.0 allows local users to overwrite arbitrary files via a symlink attack on (1) a /tmp/fab.*.tar file or (2) certain other files in the top level of /tmp/.

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.
