Title: BEA Systems WebLogic Server Directory Traversal Vulnerability
Severity: MODERATE
Description:
BEA Systems WebLogic Server is an enterprise level web and wireless application server.
It is possible for an attacker to traverse the intended structure of the web folders of a BEA Systems WebLogic Server.
Submitting a a URL containing a known directory name, and appended with specific ascii characters, will disclose the contents of the requested resource, if present. The ASCII characters in question are %00, %2e, %2f and %5c. This vulnerability could allow a user to gain access to various files residing on the target outside the webserver's specified directory tree.
This vulnerability has reportedly been exploited to disclose the source of requested .jsp files.
It should be noted that using the unicode equivalents to the maliciously-appended ascii characters has been exploited successfully.
Successful exploitation of this vulnerability could reveal sensitive data which may be used to assist in further attacks against the host.
Affected Products:
- BEA Systems Weblogic Server 4.5.1
- BEA Systems Weblogic Server 5.1.0
- BEA Systems Weblogic Server 6.0.0
