The (1) mkxmltype and (2) mkdtskel scripts in XML-DT before 0.64 allow local users to overwrite arbitrary files via a symlink attack on a /tmp/xml##### 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.

Affected Software

Name Vendor Start Version End Version
Xml-dt Xml-dt_project * 0.63 (including)
Xml-dt Xml-dt_project 0.60 (including) 0.60 (including)
Xml-dt Xml-dt_project 0.61 (including) 0.61 (including)
Xml-dt Xml-dt_project 0.62 (including) 0.62 (including)

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.
