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

linki.py in ekg 2005-06-05 and earlier allows local users to overwrite or create arbitrary files via a symlink attack on temporary files.

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
Ekg Ekg_project * 2005-06-05 (including)
Ekg Ubuntu dapper *
Ekg Ubuntu devel *
Ekg Ubuntu edgy *
Ekg Ubuntu feisty *

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.
