AI-suggested
Until an official patch is released, organizations should implement strict controls on the handling of PSD files, including blocking or sandboxing PSD attachments in email gateways and endpoint security solutions. User education is critical to prevent opening suspicious or unsolicited PSD files. Employ application whitelisting and endpoint detection and response (EDR) tools to monitor and block anomalous behaviors associated with Power PDF. Restrict user privileges to limit the impact of code execution. Network segmentation can reduce lateral movement if exploitation occurs. Monitor for unusual process activity related to Power PDF and PSD file handling. Regularly check for vendor updates or security advisories to apply patches promptly once available. Consider disabling or limiting the use of PSD file features in Power PDF if possible. Incident response plans should be updated to address potential exploitation scenarios involving this vulnerability.
Description
Kofax Power PDF PSD File Parsing Out-Of-Bounds Write 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 PSD 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-22919.
