CVE-2025-0908
Published: 11 February 2025
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.
Security Summary
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/.
