Vulnerability Details

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Novell ZENWorks. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.

The specific flaw exists within \Program Files\Common Files\InstallShield\ISGrid2.dll ActiveX control. If the DoFindReplace method is invoked with the bstrSearchText parameter set to an overly large value, a string buffer overflow will occur. This can be exploited to execute arbitrary code on the host system in the context of the browser.
