-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 AppSecInc Team SHATTER Security Advisory Oracle Enterprise Manager vulnerable to Session fixation. Risk Level: Low Affected versions: Oracle Enterprise Manager Database Control 10.2.0.5, 11.1.0.7 (and previous patchsets) Remote exploitable: Yes Credits: This vulnerability was discovered and researched by Esteban Martinez Fayo of Application Security Inc. Details: Authenticating a web user without invalidating any existing session identifier gives an attacker the opportunity to steal authenticated sessions. Oracle Enterprise Manager authenticates a user without first invalidating the existing session ID, thereby continuing to use the same session ID already associated with the session. This can be exploited in shared computer environments if the attacker navigates to the login web page /em/console/logon/logon and records the session ID associated, then closes the browser. When a legitimate user logs on, the same Session ID will be used so the attacker will be able to take over the session and perform operations on the victim's behalf. Impact: An attacker who has access to a computer with a web browser that will later be used in an Oracle Enterprise Manager web session, can know which session ID will be used, therefore will be able to impersonate the legitimate user. Vendor Status: Vendor was contacted and a patch was released. Workaround: There is no workaround for this vulnerability. Fix: Apply Oracle Critical Patch Update April 2012 available at Oracle Support.
