A vulnerability was found in EMC RSA Authentication Client 3.5. It has been rated as critical. Affected by this issue is an unknown code. The manipulation with an unknown input leads to a improper authentication vulnerability. Using CWE to declare the problem leads to CWE-287. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. Impacted is confidentiality, integrity, and availability. CVE summarizes:

The authentication functionality in EMC RSA Authentication Agent 7.1 and RSA Authentication Client 3.5 on Windows XP and Windows Server 2003, when an unspecified configuration exists, allows remote authenticated users to bypass an intended token-authentication step, and establish a login session to a remote host, by leveraging Windows credentials for that host.

The weakness was disclosed 09/20/2012 by Agent as 50735 as confirmed advisory (Secunia). The advisory is available at secunia.com. The public release has been coordinated in cooperation with the vendor. This vulnerability is handled as CVE-2012-2287 since 04/19/2012. The attack may be launched remotely. A simple authentication is needed for exploitation. Technical details are unknown but a public exploit is available.

It is declared as proof-of-concept. As 0-day the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 62438 (RSA Authentication Client 3.5 < 3.5.6 Local Authentication Bypass), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Windows and running in the context l.

Upgrading to version 7.1.1 eliminates this vulnerability. Applying the patch 3.5.6 is able to eliminate this problem. The best possible mitigation is suggested to be patching the affected component. A possible mitigation has been published immediately after the disclosure of the vulnerability.
