Information in this document applies to any platform.
Problem with the security-constraint implementation on Weblogic server 10.3. Attached a sample application to illustrate the problem.
Essentially the problem is -
Assume the following in the web.xml:
<display-name>Administrator User Only Resources</display-name>
In section "SRV.12.8.1 Combining Constraints" of the Servlet 2.4 spec it say:
Following this, the resource "NoAccess" above should take precedence and preclude access even though the previous constraint grants access. Unfortunately it does not for the *.pdf pattern, but does for the /doc2/* pattern.
When you access the application you will be offered the following files to access:
Based on the above rules, all should present the user with a 403 error. However, only the doc2/readme.pdf does.
When the WLS 8.1 application is rewritten with a similar rule set it worked correctly, but when rewritten for 10.3 and deployed it is allowing access to files that should be blocked which is a major security hole.
