SoftArtisans XFile FileManager ActiveX control stack buffer overflows

Vulnerability Note VU#914785

Original Release Date: 2008-08-25 | Last Revised: 2008-08-25


The SoftArtisans XFile FileManager ActiveX control contains several stack buffer overflows, which can allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.


SoftArtisans XFile is an ActiveX file transfer application. The XFile FileManager ActiveX control, which is included with XFile, contains multiple stack buffer overflow vulnerabilities. The XFile FileManager ActiveX control is provided by the file SAFmgPws.dll. Vulnerable methods include BuildPath(), GetDriveName(), DriveExists(), and DeleteFile().


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. The attacker could also cause Internet Explorer (or the program using the WebBrowser control) to crash.
