Published: 11 February 2025
Summary
CVE-2024-12547 is a high-severity Out-of-bounds Write (CWE-787) vulnerability in Tungstenautomation Power Pdf. Its CVSS base score is 8.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Client Execution (T1203); ranked in the top 34.5% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2024-12547 is an out-of-bounds write vulnerability in the JPF file parsing component of Tungsten Automation Power PDF, enabling remote code execution. The issue stems from a lack of proper validation of user-supplied data within JPF files, resulting in a write past the end of an allocated object. This flaw affects installations of Tungsten Automation Power PDF and was disclosed as ZDI-CAN-25560.
Remote attackers can exploit the vulnerability by inducing a target user to visit a malicious web page or open a malicious file, as user interaction is required. No privileges are needed (PR:N), and exploitation occurs over the network (AV:N) with low complexity (AC:L). Successful attacks allow arbitrary code execution in the context of the current process, with impacts including high confidentiality, integrity, and availability (C:H/I:H/A:H). The vulnerability carries a CVSS v3.1 base score of 8.8 and maps to CWE-787 (Out-of-bounds Write).
Details on the vulnerability, including mitigation recommendations, are provided in the Zero Day Initiative advisory ZDI-24-1681 at https://www.zerodayinitiative.com/advisories/ZDI-24-1681/.
