Name of the Vulnerable Software and Affected Versions Foxit Reader version 9.4.1.16828

Description This issue allows remote attackers to execute arbitrary code on vulnerable installations. User interaction is required, where the target must visit a malicious page or open a malicious file. The flaw exists within the ToggleFormsDesign method of the Foxit.FoxitReader.Ctl ActiveX object, due to the lack of validating the existence of an object prior to performing operations on it. An attacker can leverage this to execute code in the context of the current process.

Recommendations For Foxit Reader version 9.4.1.16828, consider disabling the ToggleFormsDesign method of the Foxit.FoxitReader.Ctl ActiveX object as a temporary workaround until a patch is available. Restrict access to malicious pages or files to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
