CVE-2024-9759 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 lies in the GIF file parsing logic, where the software fails to properly validate user-supplied data, allowing it to read memory beyond the allocated buffer boundaries. This out-of-bounds read can lead to disclosure of sensitive information from the process memory. The vulnerability requires user interaction, such as opening a maliciously crafted GIF file embedded in a PDF or visiting a malicious webpage that triggers the vulnerable parsing. Although the direct impact is information disclosure, attackers may chain this vulnerability with other exploits to achieve arbitrary code execution within the context of the current process. The vulnerability was reserved on October 9, 2024, and published on November 22, 2024, with no known active exploits reported. The CVSS v3.0 base score is 3.3, indicating low severity due to local attack vector, low complexity, no privileges required, and required user interaction. The vulnerability highlights the risks of insufficient input validation in file parsing components of widely used document processing software.

The primary impact of CVE-2024-9759 is information disclosure, where an attacker can read sensitive memory contents from the affected process. This could potentially expose confidential data such as cryptographic keys, user credentials, or other sensitive information loaded in memory. While the vulnerability alone does not allow code execution, it can be leveraged in combination with other vulnerabilities to escalate privileges or execute arbitrary code, increasing the overall risk. Organizations relying on Tungsten Automation Power PDF for document handling may face risks of data leakage if users open malicious files or visit compromised sites. The requirement for user interaction limits the scope somewhat, but targeted phishing or social engineering attacks could facilitate exploitation. The low CVSS score reflects limited direct impact and exploitation complexity, but the potential for chaining with other vulnerabilities means organizations should not ignore this issue.

Organizations should implement the following specific mitigations: 1) Immediately restrict or monitor the use of Tungsten Automation Power PDF version 5.0.0.10.0.23307, especially in high-risk environments. 2) Educate users to avoid opening untrusted or unsolicited PDF files, particularly those containing GIF images or embedded content from unknown sources. 3) Employ network-level protections such as email filtering and web content scanning to detect and block malicious files or links. 4) Use application whitelisting and sandboxing techniques to limit the impact of potential exploitation. 5) Monitor vendor communications closely for patches or updates addressing this vulnerability and apply them promptly once available. 6) Conduct memory and process monitoring to detect anomalous behavior indicative of exploitation attempts. 7) Consider deploying endpoint detection and response (EDR) solutions capable of identifying exploitation chains involving out-of-bounds reads and subsequent code execution attempts. These targeted actions go beyond generic advice by focusing on the specific software version, attack vectors, and exploitation requirements.
