CVE-2006-0591
1.2 · LOWOverview
CVE-2006-0591 is a low-severity vulnerability affecting solar_designer crypt_blowfish. It was published on February 8, 2006 and has a CVSS 2.0 base score of 1.2 (LOW).
This vulnerability has a CVSS 2.0 base score of 1.2, rated LOW. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical Description
The crypt_gensalt functions for BSDI-style extended DES-based and FreeBSD-sytle MD5-based password hashes in crypt_blowfish 0.4.7 and earlier do not evenly and randomly distribute salts, which makes it easier for attackers to guess passwords from a stolen password file due to the increased number of collisions.
Remediation
Check the references section for vendor advisories and patches from solar_designer. Update crypt_blowfish 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.
