This vulnerability has a CVSS 2.0 base score of 5.0, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

The blowfish mode in DAR before 2.3.4 uses weak Blowfish-CBC cryptography by (1) discarding random bits by the blowfish::make_ivec function in libdar/crypto.cpp that results in predictable and repeating IV values, and (2) direct use of a password for keying, which makes it easier for context-dependent attackers to decrypt files.

Remediation

Check the references section for vendor advisories and patches from dar. Update dar to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
