Directory traversal vulnerability in the DeploymentFileRepository class in JBoss Application Server (jbossas) 3.2.4 through 4.0.5 allows remote authenticated users to read or modify arbitrary files, and possibly execute arbitrary code, via unspecified vectors related to the console manager.

The default configuration of JBoss does not restrict access to the (1) console and (2) web management interfaces, which allows remote attackers to bypass authentication and gain administrative access via direct requests.

The Access Control functionality (JMXOpsAccessControlFilter) in JMX Console in JBoss Application Server 4.0.2 and 4.0.5 before 20070416 uses a member variable to store the roles of the current user, which allows remote authenticated administrators to trigger a race condition and gain privileges by logging in during a session by a more privileged administrator, as demonstrated by privilege escalation from Read Mode to Write Mode.

When using multi-user authentication provided by the "allow-multiple-users" option for the datasource's connection pool together with a security domain, the credentials provided as arguments to the getConnection(uid,pwd) function are ignored. This means that a valid connection will be returned for an invalid credential.

This could also mean that, provided the correct subject, a datasource connection can be obtained that which might belong to a privileged user.

A fix for this issue is already available up-stream. The up-stream fix is located at [jira JBJCA-864].
