Descriptions

The authentication protocol in Oracle Database Server 10.2.0.3, 10.2.0.4, 10.2.0.5, 11.1.0.7, 11.2.0.2, and 11.2.0.3 allows remote attackers to obtain the session key and salt for arbitrary users, which leaks information about the cryptographic hash and makes it easier to conduct brute force password guessing attacks, aka "stealth password cracking vulnerability."

El protocolo de autenticación en Oracle Database 11g 1 y 2 permite a atacantes remotos obtener la clave y la "salt" de sesión para usuarios de su elección, lo cual provoca fugas de información sobre el hash criptográfico y hace que sea más fácil ataques de fuerza bruta para adivinar la contraseña. Se trata de un problema también conocido como "vulnerabilidad de ruptura de contraseñas".

Oracle database versions 11g R1 and R2 suffers from an authentication bypass vulnerability.
