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

p7zip 9.20.1 allows remote attackers to write to arbitrary files via a symlink attack in an archive.

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
Fedora Fedoraproject 22 22
Fedora Fedoraproject 23 23

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.
