CVE-2024-9754 is a security vulnerability classified as CWE-125 (Out-of-bounds Read) affecting Tungsten Automation Power PDF version 5.0.0.10.0.23307. The vulnerability resides in the PDF file parsing component, where insufficient validation of user-supplied data leads to reading memory beyond the bounds of allocated objects. This flaw can cause disclosure of sensitive information from the process memory, potentially leaking confidential data. Although the vulnerability itself does not directly allow code execution, it can be exploited in combination with other vulnerabilities to execute arbitrary code within the context of the application. The attack vector is local with user interaction required, meaning the victim must open a crafted malicious PDF file or visit a malicious webpage that triggers the vulnerability. The CVSS v3.0 base score is 3.3, reflecting low severity due to limited confidentiality impact and no integrity or availability impact. The vulnerability was assigned by ZDI (ZDI-CAN-24471) and published on November 22, 2024. No patches or known exploits are currently available, but the risk remains for users of the affected Power PDF version. The vulnerability highlights the importance of robust input validation in PDF parsing to prevent memory safety issues.

The primary impact of CVE-2024-9754 is information disclosure, where attackers can read sensitive data from the memory of the affected process. This could include fragments of documents, credentials, or other confidential information processed by Power PDF. While the vulnerability alone does not compromise system integrity or availability, the potential to chain this flaw with other vulnerabilities raises the risk of arbitrary code execution, which could lead to full system compromise. Organizations relying on Tungsten Automation Power PDF for document handling may face data leakage risks, especially if users open untrusted PDF files. The requirement for user interaction and local access reduces the likelihood of widespread automated exploitation but does not eliminate targeted attacks. The absence of known exploits currently limits immediate risk, but the vulnerability should be addressed promptly to prevent future exploitation. Sensitive sectors such as finance, legal, and government that frequently handle confidential PDFs are particularly at risk.

To mitigate CVE-2024-9754, organizations should: 1) Immediately restrict the use of affected Power PDF versions (5.0.0.10.0.23307) and monitor for official patches or updates from Tungsten Automation. 2) Implement strict policies to prevent users from opening PDF files from untrusted or unknown sources, including email attachments and web downloads. 3) Employ endpoint security solutions capable of detecting and blocking malicious PDF files or suspicious behaviors related to PDF parsing. 4) Educate users about the risks of opening unsolicited or suspicious PDF documents and encourage verification before opening. 5) Use application whitelisting to limit execution of unauthorized software and sandbox PDF viewers where possible to contain potential exploits. 6) Monitor network and endpoint logs for unusual activity that could indicate exploitation attempts. 7) Consider alternative PDF processing tools with a strong security track record until a patch is available. These steps go beyond generic advice by focusing on user behavior, application controls, and layered defenses tailored to the vulnerability's characteristics.
