CVE-2012-4449

9.8 criticalEPSS 1.2%

Critical (9.8) in apache hadoop. EPSS 1.2% chance of exploitation in the next 30 days. Fixed in org.apache.hadoop:hadoop-client 0.23.4, 1.0.4, 2.0.2.

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.
