Detailsinfo

A vulnerability was found in Lenovo Access Support. It has been declared as critical. This vulnerability affects some unknown processing in the library acpcontroller.dll of the component ActiveX Control. The manipulation with an unknown input leads to a authentication spoofing vulnerability. The CWE definition for the vulnerability is CWE-290. This attack-focused weakness is caused by incorrectly implemented authentication schemes that are subject to spoofing attacks. As an impact it is known to affect integrity, and availability. CVE summarizes:

The IBM Lenovo Access Support acpRunner ActiveX control, as distributed in acpcontroller.dll before 1.2.8.0 and possibly acpir.dll before 1.0.0.9 (Automated Solutions 1.0 before fix pack 1), does not properly validate digital signatures of downloaded software, which makes it easier for remote attackers to spoof a download.

The bug was discovered 08/14/2007. The weakness was presented 08/14/2007 by Karl Lynn with Juniper Networks as confirmed advisory (CERT.org). The advisory is available at kb.cert.org. This vulnerability was named CVE-2007-2240 since 04/25/2007. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Technical details are known, but there is no available exploit.

It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 25883 (MS07-045: Cumulative Security Update for Internet Explorer (937143)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Windows : Microsoft Bulletins and running in the context l.
