CVE-2024-27343 is a security vulnerability classified as CWE-125 (Out-of-bounds Read) found in Kofax Power PDF version 5.0.0.57. The flaw arises from insufficient validation of user-supplied data during PDF file parsing, which allows an attacker to read memory beyond the intended buffer boundaries. This out-of-bounds read can lead to disclosure of sensitive information residing in adjacent memory areas. The vulnerability requires user interaction, such as opening a maliciously crafted PDF file or visiting a malicious webpage that triggers the vulnerable parsing logic. Although the immediate impact is limited to information disclosure, the vulnerability can be leveraged in combination with other vulnerabilities to execute arbitrary code within the context of the current process, potentially leading to full compromise. The CVSS v3.0 base score is 3.3, reflecting a low severity primarily due to the requirement for user interaction and the limited scope of confidentiality impact. No patches or official fixes have been linked yet, and no active exploitation has been reported. The vulnerability was initially reported by the Zero Day Initiative (ZDI) under the identifier ZDI-CAN-22929. The affected product is widely used in enterprise and professional environments for PDF document handling, making awareness and mitigation important.

The primary impact of CVE-2024-27343 is the unauthorized disclosure of sensitive information from the memory of affected systems running Kofax Power PDF 5.0.0.57. While the vulnerability alone does not allow code execution, it can be chained with other vulnerabilities to escalate privileges or execute arbitrary code, increasing the risk of full system compromise. Organizations relying on Kofax Power PDF for document processing may face risks of data leakage, especially if users open untrusted or malicious PDF files. This can lead to exposure of confidential information, intellectual property, or credentials stored in memory. The requirement for user interaction limits the attack surface but does not eliminate risk, particularly in environments where users frequently handle external documents. The lack of known exploits in the wild reduces immediate threat but does not preclude future exploitation attempts. Overall, the vulnerability poses a low to moderate risk depending on the environment and presence of additional vulnerabilities.

To mitigate CVE-2024-27343 effectively, organizations should: 1) Immediately restrict or monitor the use of Kofax Power PDF 5.0.0.57 in high-risk environments until a vendor patch is available. 2) Educate users about the risks of opening PDF files from untrusted or unknown sources, emphasizing caution with email attachments and downloads. 3) Implement application whitelisting and sandboxing for PDF readers to limit the impact of potential exploitation. 4) Employ network-level protections such as email filtering and web content scanning to detect and block malicious PDF files. 5) Monitor vendor communications closely for security updates or patches and apply them promptly once released. 6) Conduct regular memory and process monitoring on endpoints running Kofax Power PDF to detect anomalous behavior indicative of exploitation attempts. 7) Consider alternative PDF readers with a stronger security track record if patching is delayed. These steps go beyond generic advice by focusing on user behavior, layered defenses, and proactive monitoring tailored to this specific vulnerability.
