AppSecInc Team SHATTER Security Advisory
HTTP Response Splitting in Oracle Enterprise Manager (prevPage parameter).
Risk Level: Medium
Affected versions: Oracle Enterprise Manager Database Control 10.2.0.5, 184.108.40.206, 220.127.116.11 (and previous patchsets) Oracle Enterprise Manager Grid Control 10.2.0.5 (and previous patchsets)
Remote exploitable: Yes
Credits: This vulnerability was discovered and researched by Esteban Martinez Fayo of Application Security Inc.
Details: HTTP Response Splitting is a web application vulnerability where input parameters are unsafely used in response headers allowing an attacker to make the server print one (or more) new line sequences in the header section which allows to set arbitrary headers, take control of the body, or break the response into two or more separate responses. This can be used to perform cross-site scripting, cross-user defacement and web cache poisoning, among other attacks. The 'prevPage' parameter of web page /em/console/database/schema/table is vulnerable to this kind of attacks.
Impact: An attacker that convinces a valid Oracle Enterprise Manager user to click or open a malicious link can take over the user's session.
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.
