Detailsinfo

A vulnerability was found in Adobe Shockwave Player 11.6.8.638 (Multimedia Player Software) and classified as problematic. This issue affects some unknown processing of the component Compatibility Parameter Handler. The manipulation of the argument playerVersion with the input value 10 leads to a privileges management vulnerability. Using CWE to declare the problem leads to CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Adobe Shockwave Player through 11.6.8.638 allows remote attackers to trigger installation of a Shockwave Player 10.4.0.025 compatibility feature via a crafted HTML document that references Shockwave content with a certain compatibility parameter, related to a "downgrading" attack.

The weakness was presented 12/17/2012 by Will Dormann with Cert/CC as VU#546769 as confirmed advisory (Website). It is possible to read the advisory at kb.cert.org. The vendor was not involved in the public release. The identification of this vulnerability is CVE-2012-6270 since 12/06/2012. The exploitation is known to be difficult. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Technical details as well as a public exploit are known. The attack technique deployed by this issue is T1068 according to MITRE ATT&CK. Using the compatibility parameter will force the program to downgrade to the insecure version 10.4.0.025. This may allow an attacker to execute arbitrary code.

A public exploit has been developed by Will Dormann and been published immediately after the advisory. The exploit is available at kb.cert.org. It is declared as proof-of-concept. The commercial vulnerability scanner Qualys is able to test this issue with plugin 120738 (Adobe Shockwave Player Multiple Vulnerabilities).

It is possible to mitigate the problem by applying the configuration setting Disable ActiveX Controls. A possible mitigation has been published immediately after the disclosure of the vulnerability. The Shockwave Player ActiveX control can be disabled in Internet Explorer by setting the kill bit for the following CLSIDs: {166B1BCA-3F9C-11CF-8075-444553540000} / {233C1507-6A77-46A4-9443-F871F945D258}.
