ACROS Security Problem Report #2005-05-24-2
ASPR #2005-05-24-2: HTML Injection in BEA WebLogic Server Console (2)
Document ID: ASPR #2005-05-24-2-PUB
Vendor: BEA Systems (http://www.bea.com)
Target: WebLogic Server and WebLogic Express, Service Pack 4
Impact: An HTML injection vulnerability exists in WebLogic
Server Console, enabling attackers to hijack
administrative sessions using cross site scripting
Status: Official patch available, workarounds available
Discovered by: Mitja Kolsek of ACROS Security
There is a vulnerability in WebLogic Server Console login page that
allows the attacker to assume administrator's identity and thus gain
administrative access to Server Console. It is possible to inject
his username and password are silently transmitted to attacker's web
- WebLogic Server 8.1, Service Pack 4 - affected
- WebLogic Server 7.0, Service Pack 2 - not affected
- WebLogic Express 7.0, Service Pack 6 - affected
Older versions are likely to be affected as well.
Cross site scripting is a very common problem with web-based applications.
Basically it is present whenever the server is willing to include user's
to the browser unsanitized, somewhere within the generated web page. This
script, when executed, has access to all information within and about the
received web page, including the cookies.
The main differentiator of this particular vulnerability is that the
attacker need not trick the administrator into visiting a malicious web
site while being in an administrative session. Furthermore, in contrast to
other cross-site scripting vulnerabilities, this vulnerability allows the
attacker to also obtain administrator's username and password - and not
"only" his session identifier (ADMINCONSOLESESSION).
BEA Systems has issued a security bulletin  and published a patch
which fixes this issue.
- Always close all browser instances/windows and delete all cookies before
logging in to WebLogic Server Console.
 BEA Systems Security Advisory BEA05-80.00
We would like to acknowledge Gordon Engel of BEA Systems for extremely
diligent and professional handling of the identified vulnerability.
