Apache Hadoop up to 0.23.3/1.0.3/2.0.1 Kerberos Security Feature Key risky encryption

CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability classified as critical has been found in Apache Hadoop up to 0.23.3/1.0.3/2.0.1 (Network Management Software). This affects an unknown part of the component Kerberos Security Feature. The manipulation with an unknown input leads to a risky encryption vulnerability (Key). CWE is classifying the issue as CWE-327. The product uses a broken or risky cryptographic algorithm or protocol. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Apache Hadoop before 0.23.4, 1.x before 1.0.4, and 2.x before 2.0.2 generate token passwords using a 20-bit secret when Kerberos security features are enabled, which makes it easier for context-dependent attackers to crack secret keys via a brute-force attack.

The bug was discovered 10/12/2012. The weakness was presented 10/30/2017 (Website). It is possible to read the advisory at mail-archives.apache.org. This vulnerability is uniquely identified as CVE-2012-4449 since 08/21/2012. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. The technical details are unknown and an exploit is not publicly available.
