CVE-2024-5511 is a vulnerability identified in Kofax Power PDF version 5.0.0.57, specifically within the JP2 (JPEG 2000) image file parsing component. The root cause is an out-of-bounds read condition (CWE-125) due to insufficient validation of user-supplied data during JP2 file processing. When a maliciously crafted JP2 file is opened or rendered, the parser reads beyond the allocated memory buffer, which can corrupt memory and potentially allow an attacker to execute arbitrary code within the context of the current process. This vulnerability requires user interaction, such as opening a malicious file or visiting a malicious webpage that triggers the vulnerable parser. The CVSS v3.0 base score is 7.8, reflecting high severity, with attack vector local (AV:L), low attack complexity (AC:L), no privileges required (PR:N), and user interaction required (UI:R). The impact includes full compromise of confidentiality, integrity, and availability of the affected system. Although no public exploits are currently known, the vulnerability was reported through the Zero Day Initiative (ZDI) as ZDI-CAN-22020, indicating credible discovery and responsible disclosure. The lack of a patch at the time of publication necessitates immediate risk mitigation. This vulnerability is critical for organizations relying on Kofax Power PDF for document management, especially those processing JP2 images embedded in PDFs or other documents.

The impact of CVE-2024-5511 is significant for organizations using Kofax Power PDF, particularly version 5.0.0.57. Successful exploitation allows remote attackers to execute arbitrary code with the privileges of the user running the application, potentially leading to full system compromise. This can result in data theft, unauthorized access to sensitive documents, 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 JP2 files or links. Organizations in sectors such as finance, legal, government, and healthcare that rely heavily on PDF document workflows are at heightened risk. The absence of known public exploits currently limits immediate widespread exploitation, but the high severity and ease of exploitation once a malicious file is opened make this a critical threat to address proactively.

1. Monitor Kofax communications and security advisories closely for official patches or updates addressing CVE-2024-5511 and apply them promptly once available. 2. Until patches are released, restrict or disable the opening of JP2 (JPEG 2000) image files within Kofax Power PDF where possible, or configure the software to disable automatic rendering of embedded images. 3. Implement strict email and web filtering to block or quarantine suspicious files, especially those containing JP2 images or unknown attachments. 4. Educate users about the risks of opening unsolicited or unexpected PDF files and encourage verification of file sources. 5. Employ endpoint detection and response (EDR) tools to monitor for anomalous behavior indicative of exploitation attempts. 6. Use application whitelisting and least privilege principles to limit the impact of potential code execution. 7. Consider sandboxing or opening PDFs in isolated environments to contain potential exploits. 8. Maintain up-to-date backups and incident response plans to recover quickly from any compromise.
