Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly addresses the lack of proper validation of user-supplied data in U3D file parsing to prevent out-of-bounds reads.
Requires timely flaw remediation through patching PDF-XChange Editor to fix the specific U3D parsing vulnerability.
Implements memory protection mechanisms to mitigate impacts of out-of-bounds reads, such as information disclosure and potential code execution.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Out-of-bounds read in PDF parsing enables client-side exploitation (info disclosure or chained RCE) via malicious file opened by user.
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 object. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process. Was ZDI-CAN-25957.
Deeper analysisAI
CVE-2025-0911 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 object, 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 without privileges can exploit this vulnerability by inducing a target user to visit a malicious webpage or open a malicious file, as user interaction is required. Exploitation primarily results in sensitive information disclosure, but the issue can be leveraged in conjunction with other vulnerabilities to execute arbitrary code within the context of the PDF-XChange Editor process.
The Zero Day Initiative has published advisory ZDI-25-066, which details the vulnerability (originally tracked as ZDI-CAN-25957) and was published on 2025-02-11.
