AI-suggested
1. Monitor Kofax communications and security advisories for official patches or updates addressing CVE-2024-5305 and apply them promptly once released. 2. Until patches are available, implement application whitelisting to restrict execution of untrusted PDF files and limit Power PDF usage to trusted sources. 3. Employ endpoint protection solutions with behavior-based detection to identify and block exploitation attempts targeting buffer overflows. 4. Educate users about the risks of opening unsolicited or suspicious PDF files and links, emphasizing cautious handling of email attachments and web content. 5. Use network-level controls such as email filtering and web proxy solutions to block or quarantine potentially malicious PDFs. 6. Consider sandboxing or isolating Power PDF usage in virtualized or containerized environments to limit potential damage from exploitation. 7. Regularly audit and restrict user privileges to minimize the impact of a compromised process. 8. Enable exploit mitigation technologies such as Data Execution Prevention (DEP) and Address Space Layout Randomization (ASLR) on endpoints running Power PDF to increase exploitation difficulty.
Description
Kofax Power PDF PDF File Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Kofax Power PDF. 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 PDF files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-22921.
