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

Description This issue allows remote attackers to disclose sensitive information 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 resetForm method when processing AcroForms, resulting from the lack of validating the existence of an object prior to performing operations on it. An attacker can leverage this, in conjunction with other issues, to execute code in the context of the current process.

Recommendations For Foxit Reader version 9.4.1.16828, consider disabling the resetForm method when processing AcroForms 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 issue.
