Overview

HP Online Support Services contains the function MoveFile(), which can be exploited to cause a buffer overflow. This may allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.

Description

HP Services provides online product support services including HP Instant Support. The HPISDataManager.dll ActiveX control contains the insecure function MoveFile(), which can be exploited by a malicious attacker to cause a buffer overflow on a vulnerable system.

Note that the HP Support Services ActiveX control is locked to certain domains, such as hp.com. This means that an attacker would have to subvert the host name lookup methodology on a victim’s system or exploit a cross-site scripting vulnerability in one of the allowed domains to exploit this vulnerability.

Impact

By convincing a user to visit a malicious web page, a remote unathenticated attacker could exploit this vulnerability to execute arbitrary code on a vulnerable system.

Solution

Install HP Instant Support - v1.0.0.24 or later. For installation instructions, please visit the HP Support Document.
