-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Team SHATTER Security Advisory Cross-site scripting in Oracle Enterprise Manager (REFRESHCHOICE Parameter) August 4, 2008 Risk Level: High Affected versions: Oracle Enterprise Manager Database Control 10gR1, 10gR2 and 11g (11.1.0.6) Remote exploitable: Yes Credits: This vulnerability was discovered and researched by Esteban Martínez Fayó of Application Security Inc. Details: Cross-site scripting vulnerabilities occur when an attacker tricks a legitimate web application into sending malicious code, generally in the form of a script, to an unsuspecting end user. The attack usually involves crafting a hyperlink with malicious script code embedded within it. A valid user is likely to click this link since it points to a resource on a trusted domain. The link can be posted on a web page, or sent in an instant message, or email. Clicking on the link executes the attacker-injected code in the context of the trusted web application. Typically, the code steals session cookies, which can then be used to impersonate a valid user. The "REFRESHCHOICE" parameter used in web pages of Oracle Enterprise Manager are vulnerable to cross-site scripting attacks. User supplied input to these parameters is returned without proper sanitization, allowing a malicious attacker to inject arbitrary scripting code. Impact: Attackers might steal administrator's session cookies, thereby allowing the attacker to impersonate the valid user. Vendor Status: Vendor was contacted and a patch was released. Workaround: There is no workaround for this issue. Fix: Apply Oracle Critical Patch Update July 2008 available at Oracle Metalink.
