Published: 11 February 2025
Summary
CVE-2025-0908 is a high-severity Out-of-bounds Read (CWE-125) vulnerability in Pdf-Xchange Pdf-Xchange Editor. Its CVSS base score is 8.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Drive-by Compromise (T1189); ranked at the 36.1th percentile by exploit likelihood (below the median); 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-16 (Memory Protection).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Timely flaw remediation through patching PDF-XChange Editor directly eliminates the out-of-bounds read vulnerability in U3D file parsing.
Information input validation ensures proper bounds checking and validation of user-supplied U3D data before parsing, addressing the root cause of the buffer over-read.
Memory protection mechanisms like address space layout randomization and data execution prevention mitigate information disclosure and potential code execution from the out-of-bounds read.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Vulnerability is triggered by user opening crafted U3D/PDF file (T1204.002) or visiting malicious site (T1189), enabling client-side exploitation (T1203) and memory disclosure that can chain to code execution.
NVD Description
PDF-XChange Editor U3D File Parsing Out-Of-Bounds Read Information Disclosure Vulnerability. This vulnerability allows remote attackers to disclose sensitive information on affected installations of PDF-XChange Editor. User interaction is required to exploit this vulnerability in that the target must visit a…

malicious page or open a malicious file. The specific flaw exists within the parsing of U3D files. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process. Was ZDI-CAN-25557.
Deeper analysisAI
CVE-2025-0908 is an out-of-bounds read information disclosure vulnerability in PDF-XChange Editor, stemming from inadequate validation of user-supplied data during U3D file parsing. This flaw enables a read access past the end of an allocated buffer, potentially exposing sensitive information from affected installations. It is classified under CWE-125 and carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).
Remote attackers can exploit the vulnerability by inducing a target user to visit a malicious webpage or open a malicious file containing a specially crafted U3D file. Exploitation requires user interaction but no privileges, allowing disclosure of sensitive memory contents. Attackers can further leverage this issue in combination with other vulnerabilities to achieve arbitrary code execution within the context of the PDF-XChange Editor process.
Details on the vulnerability were disclosed by the Zero Day Initiative in advisory ZDI-25-063, originally tracked as ZDI-CAN-25557, available at https://www.zerodayinitiative.com/advisories/ZDI-25-063/.
