CVE-2024-47810
CVE-2024-47810 is a use-after-free vulnerability in Foxit Reader that allows for arbitrary code execution. By embedding malicious Javascript in a PDF, attackers can exploit how Foxit Reader handles 3D page objects, leading to memory corruption. The SVRS score is 40, indicating a moderate risk, but potential for significant impact if successfully exploited.
CVE-2024-47810 highlights a critical flaw in Foxit Reader (version 2024.3.0.26795). This use-after-free vulnerability (CWE-416) can be triggered when a user opens a specially crafted PDF containing malicious JavaScript. Successful exploitation leads to arbitrary code execution, granting an attacker significant control over the affected system. While the CVSS score is 0, the SVRS of 40 suggests a moderate level of real-world risk, further evidenced by the "In The Wild" tag, indicating active exploitation. Organizations using Foxit Reader should apply available patches immediately to mitigate this serious threat.
Description
CVE-2024-47810 is a use-after-free vulnerability impacting Foxit Reader 2024.3.0.26795.
