Open-source ARJ archiver 3.10.22 allows remote attackers to conduct directory traversal attacks via a symlink attack in an ARJ 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
Arj_archiver Arj_software * 3.10.22 (including)
Arj Ubuntu lucid *
Arj Ubuntu precise *
Arj Ubuntu trusty *
Arj Ubuntu upstream *
Arj Ubuntu utopic *
Arj Ubuntu vivid *

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.
