AI-suggested

  1. Apply patches or updates from Foxit as soon as they become available to address CVE-2024-30357.
  2. Until patches are released, consider disabling or restricting the use of Foxit PDF Reader 2023.3.0.23028, especially in high-risk environments.
  3. Employ application whitelisting to prevent execution of unauthorized or suspicious PDF reader versions.
  4. Use endpoint protection solutions with behavioral detection to identify and block exploitation attempts involving malicious PDFs.
  5. Educate users to avoid opening PDF files from untrusted or unknown sources and to be cautious with email attachments and links.
  6. Implement network-level protections such as sandboxing or proxy scanning of PDF files before delivery to end users.
  7. Monitor logs and endpoint telemetry for unusual process behavior or crashes related to Foxit PDF Reader.
  8. Consider deploying alternative PDF readers with a strong security track record if immediate patching is not feasible.
  9. Maintain regular backups and incident response plans to mitigate potential damage from exploitation. These measures combined can reduce the attack surface and limit the impact of this vulnerability.

Description

Foxit PDF Reader AcroForm Annotation Type Confusion Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit PDF Reader. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the handling of Annotation objects in AcroForms. The issue results from the lack of proper validation of user-supplied data, which can result in a type confusion condition. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-22818.
