CVE-2024-27334 is a security vulnerability classified as CWE-125 (Out-of-bounds Read) found in Kofax Power PDF, specifically affecting the JPG file parsing component. The flaw arises from insufficient validation of user-supplied data during JPG parsing, which can cause the application to read memory beyond the allocated buffer boundaries. This out-of-bounds read can lead to the disclosure of sensitive information residing in adjacent memory areas. The vulnerability requires user interaction, such as opening a crafted malicious JPG file or visiting a malicious webpage that triggers the vulnerable parser. Although the immediate impact is information disclosure, attackers may combine this vulnerability with other exploits to execute arbitrary code within the context of the affected process. The affected version identified is 5.0.0.57 (5.0.0.10.0.23307). The CVSS 3.0 base score is 3.3, reflecting low severity due to limited confidentiality impact, no integrity or availability impact, local attack vector requiring user interaction, and no privileges required. As of the publication date, no public exploits or active exploitation have been reported. The vulnerability was reserved and assigned by the Zero Day Initiative (ZDI) under ZDI-CAN-21978. No official patches have been linked yet, so users should monitor vendor advisories closely.

The primary impact of CVE-2024-27334 is the potential disclosure of sensitive information from the memory space of the Kofax Power PDF process. This could include fragments of documents, user data, or other sensitive information temporarily held in memory during JPG parsing. While the vulnerability alone does not allow code execution or system compromise, it lowers the barrier for attackers to chain this flaw with other vulnerabilities to escalate privileges or execute arbitrary code. For organizations, this could lead to data leakage, privacy violations, and potential footholds for further attacks if combined with other exploits. The requirement for user interaction limits large-scale automated exploitation but does not eliminate risk, especially in environments where users frequently open untrusted PDF or JPG files. The low CVSS score indicates limited immediate risk, but the possibility of escalation means organizations should not ignore this vulnerability. Sensitive sectors such as legal, financial, and government entities using Kofax Power PDF may face higher risks due to the nature of their documents.

1. Monitor Kofax official channels and security advisories for patches addressing CVE-2024-27334 and apply updates promptly once available. 2. Implement strict email and web filtering to block or quarantine suspicious JPG and PDF files from untrusted sources to reduce the risk of user interaction with malicious content. 3. Educate users about the risks of opening files from unknown or untrusted origins, emphasizing caution with email attachments and links. 4. Employ application whitelisting and sandboxing techniques to limit the impact of potential exploitation by isolating Kofax Power PDF processes. 5. Use endpoint detection and response (EDR) solutions to monitor for anomalous behavior related to Kofax Power PDF processes that might indicate exploitation attempts. 6. Consider disabling automatic preview or rendering of JPG content within Kofax Power PDF if configurable, to reduce attack surface. 7. Regularly audit and inventory software versions in use to ensure vulnerable versions are identified and remediated swiftly. 8. If possible, restrict the use of Kofax Power PDF to trusted internal users and environments where file sources are controlled.
