CVE-2024-27346 is a security vulnerability identified in Kofax Power PDF version 5.0.0.57, classified under CWE-125 (Out-of-bounds Read). The vulnerability occurs during the parsing of PDF files, where the software fails to properly validate user-supplied data, resulting in reading beyond the bounds of an allocated buffer. This out-of-bounds read can lead to the disclosure of sensitive information from the application's memory space. Although the immediate impact is information disclosure, the vulnerability can be exploited in combination with other flaws to execute arbitrary code within the context of the current process. Exploitation requires user interaction, such as opening a crafted malicious PDF file or visiting a malicious webpage that triggers the vulnerability. The CVSS 3.0 base score is 3.3, indicating a low severity primarily due to the requirement for user interaction and limited impact scope (confidentiality only). No public exploits or active exploitation in the wild have been reported to date. The vulnerability was reserved on February 23, 2024, and published on April 3, 2024, by the Zero Day Initiative (ZDI) under the identifier ZDI-CAN-22934. No official patches are currently linked, suggesting users should monitor vendor advisories closely for updates.

The primary impact of CVE-2024-27346 is the potential disclosure of sensitive information from the memory of affected Kofax Power PDF installations. This can lead to leakage of confidential data such as document contents, user credentials, or cryptographic material residing in memory. While the vulnerability itself does not directly compromise system integrity or availability, it can serve as a stepping stone for attackers to chain with other vulnerabilities to achieve arbitrary code execution, thereby escalating the threat significantly. Organizations relying on Kofax Power PDF for document handling may face risks of data leakage, especially if users are tricked into opening malicious PDFs. The requirement for user interaction limits mass exploitation but targeted attacks against high-value individuals or organizations remain a concern. The absence of known exploits in the wild reduces immediate risk but does not eliminate the potential for future attacks once exploit code becomes available.

1. Monitor Kofax vendor advisories and apply security patches promptly once released for Power PDF 5.0.0.57 or affected versions. 2. Implement strict email and web filtering to block or quarantine suspicious PDF files from untrusted sources to reduce the risk of users opening malicious documents. 3. Educate users about the risks of opening unsolicited or unexpected PDF attachments and visiting untrusted websites. 4. Employ application whitelisting and sandboxing techniques to limit the execution context of Kofax Power PDF, reducing the impact of potential exploitation. 5. Use endpoint detection and response (EDR) tools to monitor for anomalous behavior indicative of exploitation attempts. 6. Consider disabling or restricting PDF viewing capabilities in environments where document handling is not critical or can be offloaded to more secure platforms. 7. Regularly review and update security policies related to document handling and user interaction with external content.
