Impact by CVSS Score
  • ID: CVE-2006-0591
Summary:

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.

Exploitability Analysis: Local

A vulnerability exploitable with only local access requires the attacker to have either physical access to the vulnerable system or a local (shell) account. Examples of locally exploitable vulnerabilities are peripheral attacks such as Firewire/USB DMA attacks, and local privilege escalations (e.g., sudo).

Exploitability Complexity: High

Specialized access conditions exist. For example, in most configurations, the attacking party must already have elevated privileges or spoof additional systems in addition to the attacking system (e.g., DNS hijacking). The attack depends on social engineering methods that would be easily detected by knowledgeable people. For example, the victim must perform several suspicious or atypical actions. The vulnerable configuration is seen very rarely in practice. If a race condition exists, the window is very narrow.

Authentication: None

Authentication is not required to access and exploit the vulnerability.

Confidentiality Impact: Partial

There is considerable informational disclosure. Access to some system files is possible, but the attacker does not have control over what is obtained, or the scope of the loss is constrained. An example is a vulnerability that divulges only certain tables in a database.

Integrity Impact: None

There is no impact to the integrity of the system.

Availability Impact: None

There is no impact to the availability of the system.
