Descriptions

The identifier_hash for a session token in Atlassian Crowd before version 2.9.1 could potentially collide with an identifier_hash for another user or a user in a different directory, this allows remote attackers who can authenticate to Crowd or an application using Crowd for authentication to gain access to another user's session provided they can make their identifier hash collide with another user's session identifier hash.

Un hash de identificación para un token de sesión en Atlassian Crowd, en versiones anteriores a la 2.9.1, podría colisionar con un identifier_hash para otro usuario o un usuario en un directorio diferente. Esto permite a los atacantes remotos obtener acceso a la sesión de otro usuario, con tal de que puedan hacer que su hash de identificación colisione con el hash de identificación de la sesión de otro usuario.
