CVE-2024-27341 is a heap-based buffer overflow vulnerability identified in Kofax Power PDF, specifically affecting version 5.0.0.57. The flaw exists in the PDF file parsing component, where the software fails to properly validate the length of user-supplied data before copying it into a fixed-length heap buffer. This lack of bounds checking enables an attacker to craft a malicious PDF file that, when opened by a user, triggers a buffer overflow on the heap. The overflow can corrupt memory and allow arbitrary code execution within the context of the application process. Exploitation requires user interaction, such as opening a malicious file or visiting a malicious webpage hosting the crafted PDF. The vulnerability is classified under CWE-122 (Heap-based Buffer Overflow) and has a CVSS v3.0 base score of 7.8, indicating high severity. The attack vector is local (AV:L) but requires low attack complexity (AC:L), no privileges (PR:N), and user interaction (UI:R). The impact on confidentiality, integrity, and availability is high, as arbitrary code execution can lead to full system compromise depending on the user's privileges. Although no public exploits are currently known, the vulnerability was assigned and published by the Zero Day Initiative (ZDI) under the identifier ZDI-CAN-22927. No patches were listed at the time of publication, emphasizing the need for mitigation strategies until an official fix is released.

This vulnerability poses a significant risk to organizations using Kofax Power PDF, particularly version 5.0.0.57. Successful exploitation can lead to remote code execution, allowing attackers to execute arbitrary code with the same privileges as the user running the application. This can result in data theft, installation of malware, lateral movement within networks, and disruption of business operations. Since the vulnerability requires user interaction, phishing or social engineering campaigns could be used to deliver malicious PDFs. The high impact on confidentiality, integrity, and availability means sensitive documents and systems could be compromised. Organizations in sectors relying heavily on PDF workflows—such as legal, financial, healthcare, and government—are at elevated risk. The absence of known exploits in the wild currently reduces immediate threat but does not eliminate the risk of future exploitation once exploit code becomes available.

1. Monitor Kofax communications and security advisories closely for official patches or updates addressing CVE-2024-27341 and apply them promptly once available. 2. Until patches are released, implement application whitelisting to restrict execution of unauthorized or suspicious files, including PDFs from untrusted sources. 3. Employ advanced email filtering and sandboxing solutions to detect and block malicious PDF attachments or links in emails. 4. Educate users about the risks of opening PDFs from unknown or untrusted sources and encourage verification before opening attachments. 5. Use endpoint protection platforms with behavior-based detection to identify and block exploitation attempts targeting PDF parsing vulnerabilities. 6. Consider disabling or restricting the use of Kofax Power PDF in high-risk environments or replacing it with alternative PDF readers with better security track records. 7. Implement network segmentation to limit the impact of a compromised endpoint and reduce lateral movement opportunities. 8. Regularly back up critical data and verify backup integrity to enable recovery in case of compromise.
