AI-suggested
1. Immediately restrict or disable the use of Foxit PDF Reader version 2023.3.0.23028 until a patch is released. 2. Employ application whitelisting to prevent execution of unauthorized or suspicious PDF files. 3. Use sandboxing or isolated environments for opening PDF files from untrusted sources to contain potential exploits. 4. Educate users to avoid opening PDFs from unknown or untrusted origins and to be cautious of unsolicited emails or links. 5. Monitor network and endpoint logs for unusual behavior indicative of exploitation attempts, such as unexpected process creation or memory corruption indicators. 6. Implement endpoint detection and response (EDR) solutions capable of detecting exploitation techniques related to memory corruption. 7. Once available, promptly apply official patches from Foxit to remediate the vulnerability. 8. Consider disabling U3D file support in Foxit Reader if possible as a temporary workaround to reduce attack surface.
Description
Foxit PDF Reader U3D File Parsing Out-Of-Bounds Write 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 U3D files. The issue results from the lack of proper validation of user-supplied data, which can result in a write 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-22911.
