Detail
Vulnerability Note VU#340420IBM Access Support ActiveX control stack buffer overflowOverviewThe IBM Access Support ActiveX control contains a stack buffer overflow, which may allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.I. DescriptionThe IBM Access Support ActiveX control has the ability to collect system information, such as make, model, serial number, OS version, etc. This control is available on the IBM / Lenovo web site, and also may come pre-installed on IBM and Lenovo computer systems. The IBM Access Support ActiveX control, which is provided by IbmEgath.dll, contains a stack buffer overflow in the GetXMLValue() method. We have confirmed that version 3.20.284.0 is vulnerable. Other versions may also contain the flaw.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. The attacker could also cause Internet Explorer (or the program using the WebBrowser control) to crash.III. SolutionWe are currently unaware of a practical solution to this problem. Please consider the following workarounds:Disable the IBM Access Support ActiveX control in Internet Explorer
[HKEY_LOCAL_MACHINESOFTWAREMicrosoftInternet ExplorerActiveX Compatibility{74FFE28D-2378-11D5-990C-006094235084}] "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. Instructions for disabling ActiveX in the Internet Zone can be found in the "Securing Your Web Browser" document. Systems Affected

52958 | IBM Access Support ActiveX (IbmEgath.dll) GetXMLValue() Method Overflow A buffer overflow exists in IBM Access Support ActiveX control. IbmEgath.dll fails to validate data passed to the GetXMLValue() method resulting in a stack overflow. With a specially crafted website, a context-dependent attacker can cause arbitrary code execution resulting in a loss of integrity. |
