CVE-2024-9749 is a security vulnerability classified as CWE-125 (Out-of-bounds Read) found in Tungsten Automation Power PDF version 5.0.0.10.0.23307. The flaw exists in the PDF file parsing component where the software fails to properly validate user-supplied data, leading to reading beyond the allocated memory boundaries. This can cause disclosure of sensitive information from memory, potentially leaking confidential data. The vulnerability requires user interaction, such as opening a crafted malicious PDF file or visiting a malicious webpage that triggers the vulnerable parsing routine. Although the direct impact is limited to information disclosure, attackers may combine this vulnerability with other exploits to achieve arbitrary code execution within the context of the affected process. The attack vector is local (AV:L), meaning the attacker must have the ability to convince the user to open a malicious file or visit a malicious page. No privileges are required (PR:N), but user interaction is necessary (UI:R). The vulnerability does not affect integrity or availability directly. No patches were listed at the time of publication, and no known exploits have been observed in the wild. The vulnerability was tracked by the Zero Day Initiative as ZDI-CAN-24465 and published on November 22, 2024.

The primary impact of CVE-2024-9749 is the potential disclosure of sensitive information from the memory space of the Power PDF application. This could include data such as document contents, user credentials, or other sensitive information loaded in memory. While the vulnerability itself does not allow direct code execution or system compromise, it lowers the barrier for attackers to chain this flaw with other vulnerabilities to escalate privileges or execute arbitrary code. For organizations, this could lead to data leakage, loss of confidentiality, and potential compromise of systems if combined with further exploits. The requirement for user interaction limits large-scale automated exploitation, but targeted attacks against high-value users or organizations remain a concern. The low CVSS score reflects the limited scope and complexity of exploitation, but the risk increases if attackers develop reliable exploit chains. Organizations relying on Tungsten Automation Power PDF for document handling may face risks to sensitive information confidentiality and should prioritize mitigation to prevent potential escalation.

1. Monitor Tungsten Automation’s official channels for security patches addressing CVE-2024-9749 and apply updates promptly once released. 2. Implement strict policies to restrict opening PDF files from untrusted or unknown sources, especially in environments where sensitive data is handled. 3. Employ endpoint security solutions capable of detecting and blocking malicious PDF files or suspicious file parsing behavior. 4. Educate users about the risks of opening unsolicited or suspicious PDF documents and visiting untrusted websites. 5. Use application whitelisting or sandboxing techniques to isolate the Power PDF application and limit the impact of potential exploitation. 6. Consider alternative PDF readers with a strong security track record if patching is delayed or unavailable. 7. Conduct regular security assessments and penetration tests focusing on document handling workflows to identify and remediate related risks. 8. Monitor network traffic for unusual activity that could indicate exploitation attempts involving PDF files.
