CVE-2024-5302 is a critical vulnerability identified in Kofax Power PDF version 5.0.0.57, classified under CWE-787 (Out-of-bounds Write). The vulnerability stems from insufficient validation of user-supplied data during the parsing of PDF files, which leads to a write operation beyond the bounds of an allocated buffer. This memory corruption flaw can be exploited remotely by an attacker who convinces a user to open a specially crafted malicious PDF file or visit a malicious webpage containing such a file. The out-of-bounds write can corrupt memory, allowing the attacker to execute arbitrary code within the context of the current process, potentially leading to full system compromise depending on user privileges. The vulnerability requires user interaction but does not require prior authentication, increasing its risk profile. The CVSS v3.0 score of 7.8 reflects high impact on confidentiality, integrity, and availability, with low attack complexity and no privileges required. Although no known exploits are currently in the wild, the vulnerability was reported by the Zero Day Initiative (ZDI) and is publicly disclosed, indicating that attackers may develop exploits soon. The affected product, Kofax Power PDF, is widely used in enterprise environments for document management and PDF processing, making this vulnerability a significant concern for organizations relying on this software for secure document handling.

The potential impact of CVE-2024-5302 is substantial for organizations using Kofax Power PDF, particularly version 5.0.0.57. Successful exploitation allows remote attackers to execute arbitrary code, which can lead to full system compromise, data theft, or disruption of services. Since the vulnerability affects PDF parsing, a common vector for document-based attacks, it can be leveraged in phishing campaigns or drive-by downloads. The requirement for user interaction (opening a malicious file) means social engineering is a likely component of attacks. The compromise could result in loss of confidentiality (exposure of sensitive documents), integrity (alteration of files or system settings), and availability (system crashes or ransomware deployment). Given the widespread use of PDF documents in business workflows, this vulnerability could affect a broad range of sectors including finance, government, legal, and healthcare. The absence of known public exploits currently provides a window for mitigation, but the risk of exploitation will increase as proof-of-concept code or weaponized exploits emerge.

Organizations should immediately assess their use of Kofax Power PDF version 5.0.0.57 and plan to upgrade to a patched version once available. Until a patch is released, implement strict controls on PDF file handling, including disabling automatic opening of PDF files from untrusted sources and employing email filtering to block suspicious attachments. Use endpoint protection solutions capable of detecting anomalous behavior related to memory corruption exploits. Educate users about the risks of opening unsolicited or unexpected PDF files, emphasizing caution with email attachments and links. Employ application whitelisting to restrict execution of unauthorized code and consider sandboxing PDF reader applications to limit the impact of potential exploits. Monitor network and endpoint logs for unusual activity indicative of exploitation attempts. Coordinate with Kofax support for updates and advisories. Additionally, implement network segmentation to limit lateral movement if a system is compromised.
