CVE-2014-3528

Description

It was discovered that Subversion clients retrieved cached authentication credentials using the MD5 hash of the server realm string without also checking the server's URL. A malicious server able to provide a realm that triggers an MD5 collision could possibly use this flaw to obtain the credentials for a different realm.

Statement

Red Hat Enterprise Linux 5 is now in Production 3 Phase of the support and maintenance life cycle. This has been rated as having Moderate security impact and is not currently planned to be addressed in future updates.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Understanding the Weakness (CWE)

Access Control

Technical Impact: Bypass Protection Mechanism; Gain Privileges or Assume Identity

If an attacker can gain access to the hashes, then the lack of sufficient computational effort will make it easier to conduct brute force attacks using techniques such as rainbow tables, or specialized hardware such as GPUs, which can be much faster than general-purpose CPUs for computing hashes.
