Credit: David Byrne of Trustwave SpiderLabs 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..

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.
