Detail
Vulnerability Note VU#570705IBM and Lenovo Access Support acpRunner ActiveX control fails to validate digital signaturesOverviewThe 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.I. DescriptionThe 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.II. ImpactBy 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.III. SolutionApply an updateThis issue is addressed in Automated Solutions fix pack 1. This update removes the vulnerable control and also provides an updated version of the acpRunner ActiveX control that properly validates signatures of the software packages it downloads.
[HKEY_LOCAL_MACHINESOFTWAREMicrosoftInternet ExplorerActiveX Compatibility{E598AC61-4C6F-4F4D-877F-FAC49CA91FA3}] "Compatibility Flags"=dword:00000400 Disabling ActiveX controls in the Internet Zone (or any zone used by an attacker) appears to prevent exploitation of this and other ActiveX vulnerabilities.
