Name of the Vulnerable Software and Affected Versions Foxit Reader version 9.0.1.1049

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 handling of XFA Button elements, specifically when setting the formattedValue attribute, due to improper validation of an object's existence before performing operations on it. This can be leveraged to execute code under the context of the current process.

Recommendations For Foxit Reader version 9.0.1.1049, consider disabling the handling of XFA Button elements 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.
