Name of the Vulnerable Software and Affected Versions Foxit Reader version 2019.010.20098

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 handling of the value property of a Field object within AcroForms, resulting from the lack of validation of an object's existence 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 2019.010.20098, update to a version that fixes this issue to prevent exploitation. As a temporary workaround, consider restricting the use of AcroForms or the handling of the value property of Field objects until a patch is available. Avoid opening malicious files or visiting suspicious pages to minimize the risk of exploitation.
