AI-suggested
- Immediate mitigation should focus on restricting the opening of untrusted or unsolicited PDF files, especially those containing embedded 3D content or PRC files.
- Implement strict email filtering and attachment scanning to detect and quarantine suspicious PDFs.
- Employ endpoint protection solutions capable of detecting anomalous behavior related to PDF parsing or code execution.
- Use application whitelisting and sandboxing to limit the execution context of Foxit PDF Reader, reducing the impact of potential exploitation.
- Monitor for updates from Foxit and apply patches promptly once available.
- Educate users about the risks of opening PDFs from unknown or untrusted sources, emphasizing the specific threat of embedded 3D content.
- Consider deploying network-level protections such as Intrusion Prevention Systems (IPS) with signatures targeting this vulnerability once they become available.
- For high-risk environments, consider temporarily restricting or replacing Foxit PDF Reader with alternative PDF readers that are not affected until a patch is released.
Description
Foxit PDF Reader PRC File Parsing Out-Of-Bounds Read 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 parsing of PRC files. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-26773.
