BEA WebLogic connects multiple times allowing access to system
| weblogic-multiple-connection-gain-access (15826) |  High Risk |
Description:
BEA WebLogic Server and Express could allow a remote attacker to gain access to the system. The Web Services client code does not correctly associate a user's identity. A remote attacker can attempt to connect multiple times using different client certificates to cause an incorrect user identity to be associated with the attacker, allowing the attacker to gain access to the system. An attacker could exploit this vulnerability to execute arbitrary code on the system.
Consequences:
Gain Access
Remedy:
For WebLogic Server and Express 7.0:
Upgrade to Service Pack 5, when it becomes available, or upgrade to Service Pack 4 and apply the patch for this vulnerability, as listed in BEA Systems Inc. SECURITY ADVISORY (BEA04-47.00). See References.
