Vulnerability title: Authentication Bypass in Oracle Demantra
CVE: CVE-2013-5880
Vendor: Oracle
Product: Demantra
Affected version: 12.2.1
Fixed version: 12.2.3
Reported by: Oliver Gruskovnjak
Details:
The authentication filter in Oracle Demantra is broken by design.
For example the page:
/demantra/common/loginCheck.jsp
Is accessible by an unauthenticated user and is therefore listed in the
whitelisted URLs list. It is now possible to use this whitelisted URL to
access restricted URLs.
Exploit:
Sample Request:
POST /demantra/common/loginCheck.jsp/../../GraphServlet HTTP/1.1
