Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Flaw remediation directly mitigates the out-of-bounds write vulnerability by applying vendor patches to the U3D file parsing component in PDF-XChange Editor.
Memory protection safeguards such as DEP and ASLR prevent exploitation of the out-of-bounds write for remote code execution even if the software flaw remains unpatched.
Information input validation enforces bounds checking on U3D file data, addressing the lack of proper validation of user-supplied data during parsing.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Out-of-bounds write enables RCE via crafted U3D in malicious file or web page, directly mapping to user execution and drive-by vectors.
NVD Description
PDF-XChange Editor U3D File Parsing Out-Of-Bounds Write Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code 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 write past the end of an allocated object. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-25748.
Deeper analysisAI
CVE-2025-0910 is an out-of-bounds write vulnerability in the U3D file parsing component of PDF-XChange Editor, enabling remote code execution. The flaw stems from insufficient validation of user-supplied data during U3D file processing, allowing a write past the end of an allocated object. This affects installations of PDF-XChange Editor, with 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) and is associated with CWE-787 (Out-of-bounds Write). The vulnerability was originally tracked as ZDI-CAN-25748.
Remote attackers can exploit this vulnerability by tricking a target user into visiting a malicious web page or opening a malicious file containing a specially crafted U3D payload. No privileges are required (PR:N), and exploitation occurs over the network (AV:N) with low complexity (AC:L), though user interaction is necessary (UI:R). Successful exploitation allows the attacker to execute arbitrary code in the context of the PDF-XChange Editor process, potentially leading to high confidentiality, integrity, and availability impacts (C:H/I:H/A:H) within the affected scope (S:U).
The Zero Day Initiative has published an advisory at https://www.zerodayinitiative.com/advisories/ZDI-25-065/ addressing this vulnerability.
