Descriptions

Apache Tomcat 4.1.0 through 4.1.39, 5.5.0 through 5.5.27, and 6.0.0 through 6.0.18, when FORM authentication is used, allows remote attackers to enumerate valid usernames via requests to /j_security_check with malformed URL encoding of passwords, related to improper error checking in the (1) MemoryRealm, (2) DataSourceRealm, and (3) JDBCRealm authentication realms, as demonstrated by a % (percent) value for the j_password parameter.

Apache Tomcat v4.1.0 hasta v4.1.39, v5.5.0 hasta v5.5.27, y v6.0.0 hasta v6.0.18, cuando se utiliza autenticación FORM, permite a atacantes remotos enumerar nombres de usuarios válidos a través de una solicitud a /j_security_check con codificación malformada de URL de contraseñas. Está relacionado con una comprobación de errores incorrecta en los entornos de autenticación (1) MemoryRealm, (2) DataSourceRealm y (3) JDBCRealm; como se ha demostrado con un valor % (porcentaje) en el parámetro j_password.
