The IBM Lenovo Access Support acpRunner ActiveX control fails to validate digital signatures, which can allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.
The Access Support software package for IBM and Lenovo systems includes several ActiveX controls. This software package is also known as Automated Solutions. The acpRunner control, which is provided by AcpController.dll, provides several methods that can be used to download, extract, and run software from a remote server. The acpRunner ActiveX control fails to properly validate the signatures of downloaded software packages.
By convincing a user to view a specially crafted HTML document (e.g., a web page or an HTML email message or attachment), an attacker may be able to execute arbitrary code with the privileges of the user.
