PR06-08: BEA Plumtree portal internal hostname disclosure vulnerability Description: BEA Plumtree portal is vulnerable to a internal hostname disclosure vulnerability. The internal hostname of the server hosting BEA Plumtree portal is always included at the bottom of every requested HTML page within HTML comments. Date Found: 12th September 2006 Vendor contacted: 18th May 2007 Vulnerable: BEA Plumtree 5.0.2, 5.0.3, 5.0.4, 6.0.1.218452 and possibly other versions. Severity: Low Authors: Adrian Pastor and Jan Fry from ProCheckUp Ltd (www.procheckup.com) ProCheckUp thanks BEA for working with us. Vendor Status: Confirmed CVE Candidate: Not assigned Proof of concept: The following is an example of the internal hostname of Plumtree server disclosed within HTML comments: <!--Hostname: websvr01--> Consequences: This information could be useful to a malicious user attempting to gain illegal access to resources on internal systems. By following internal hostname naming conventions, an attacker could predict other internal hostnames as well. For instance, if Plumtree portal is running on a server with an internal hostname of websvr01, an attacker could predict other internal hostnames such as websvr01, websvr02, websvr03 and so on. Fix: This has been addressed in AquaLogic Interaction 6.1. MP1. This can also be addressed by making config changes in ALUI 6.x versions.
