A type confusion vulnerability (CVE-2024-30357) was discovered in Foxit PDF Reader's handling of Annotation objects in AcroForms. The vulnerability was reported to Foxit on December 20, 2023, and publicly disclosed on March 28, 2024. This security flaw affects installations of Foxit PDF Reader and requires user interaction, specifically opening a malicious file or visiting a malicious page, to be exploited (Zero Day Initiative).

The vulnerability stems from improper validation of user-supplied data when handling Annotation objects in AcroForms, resulting in a type confusion condition.

If successfully exploited, this vulnerability allows attackers to execute arbitrary code in the context of the current process, potentially gaining control over the affected system. The high CVSS score reflects the severe potential impact on confidentiality, integrity, and availability of the system (Zero Day Initiative).
