CVE-2024-27338 is an out-of-bounds read vulnerability classified under CWE-125, affecting Kofax Power PDF version 5.0.0.57. The vulnerability arises from insufficient validation in the app.response method, which processes user-supplied data. This flaw allows an attacker to read memory beyond the intended buffer, potentially leading to remote code execution within the context of the application process. Exploitation requires user interaction, such as opening a crafted malicious PDF file or visiting a malicious webpage that triggers the vulnerable code path. The vulnerability has a CVSS 3.0 base score of 7.8, indicating high severity with attack vector local, low attack complexity, no privileges required, but user interaction necessary. The impact includes full compromise of confidentiality, integrity, and availability of the affected system. Although no public exploits are known at this time, the vulnerability poses a significant risk due to the widespread use of Kofax Power PDF in enterprise environments for document handling. The lack of proper bounds checking in memory operations is a common and dangerous flaw that can be leveraged for arbitrary code execution, potentially allowing attackers to install malware, steal sensitive information, or disrupt business operations.

The vulnerability allows remote attackers to execute arbitrary code with the privileges of the user running Kofax Power PDF, potentially leading to full system compromise if the user has elevated rights. Confidentiality is at risk as attackers could access sensitive documents or data processed by the application. Integrity could be compromised by altering documents or injecting malicious content. Availability may be affected if the exploit causes application crashes or system instability. Organizations relying on Kofax Power PDF for critical document workflows could face operational disruption, data breaches, and potential lateral movement within networks. Since exploitation requires user interaction, phishing or social engineering could be used to deliver malicious files or links, increasing the attack surface. The absence of known exploits currently reduces immediate risk but does not eliminate the threat, especially as exploit code may be developed following public disclosure.

1. Monitor Kofax communications and security advisories for official patches or updates addressing CVE-2024-27338 and apply them promptly once available. 2. Implement strict email and web filtering to block or quarantine suspicious PDF files and URLs to reduce the risk of malicious file delivery. 3. Educate users about the risks of opening unsolicited or unexpected PDF documents and visiting untrusted websites. 4. Employ application whitelisting and sandboxing techniques to limit the execution context of Kofax Power PDF and contain potential exploitation. 5. Use endpoint detection and response (EDR) solutions to monitor for anomalous behavior indicative of exploitation attempts. 6. Restrict user privileges to the minimum necessary to reduce the impact of a successful exploit. 7. Consider disabling or restricting features in Kofax Power PDF that process external content if not required. 8. Conduct regular vulnerability assessments and penetration testing to identify and remediate similar memory safety issues proactively.
