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

mtx-changer.Adic-Scalar-24 in bacula-common 2.4.2 allows local users to overwrite arbitrary files via a symlink attack on a /tmp/mtx.##### temporary file, probably a related issue to CVE-2005-2995.

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
Bacula Bacula 2.4.2 (including) 2.4.2 (including)
Bacula Ubuntu dapper *
Bacula Ubuntu gutsy *
Bacula Ubuntu hardy *
Bacula Ubuntu upstream *

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.
