Finding 1: Oracle Application Framework Diagnostic Mode Bypass  
Vulnerability  
CVE: CVE-2013-0397  
  
The Oracle Application Framework supports a diagnostic and developer mode  
feature that are intended to be enabled from developer or administrative  
interfaces. However, any user can manually enable the modes by setting the  
"OADiagnostic" or "OADeveloperMode" cookies to "1".  
  
Example:  
GET request for enabling diagnostic mode  
  
GET /OA_HTML/RF.jsp?function_id=1038712&resp_id=23350&resp_appl_id=80  
0&security_group_id=0&lang_code=US&params=.1VlTZi5hyKHcE3E6mrZaB91phg4LLW-2ZXXJFOuaJdg-6ALqWl2AqDOwJZdQVEM&oas=q5-BOVjQj7_z-XSTMTne3A.. HTTP/1.1  
Host: A.B.C.D  
User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:16.0) Gecko/20100101 Firefox/16.0  
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8  
Accept-Language: en-US,en;q=0.5  
Accept-Encoding: gzip, deflate

Enabling diagnostic mode causes the server to present a "Diagnostics" link  
at the top and bottom of every page, and an "About this page" link at the  
bottom. This can be performed on pages that do not require authentication.  
  
For example, clicking on the "Diagnostics" link allows the user to enable a  
number of tracing and logging functions. Clicking on "About this page"  
presents environment and session information. The "profiles" tab in the  
"About this page" section allows access to a number of sensitive settings,  
including passwords and encryption/decryption keys.  
  
Remediation Steps:  
The vendor has addressed this security issue in the January 2013 Critical  
Patch Update.
