Last modified

CVE-2012-4449 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 1.20% chance of exploitation in the next 30 days.
