CVE-2025-0904
Published: 11 February 2025
Description
PDF-XChange Editor XPS 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 XPS 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-25422.
Security Summary
CVE-2025-0904 is an out-of-bounds read information disclosure vulnerability in PDF-XChange Editor, specifically within the parsing of XPS files. The flaw stems from insufficient validation of user-supplied data, allowing a read access 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-125 (Out-of-bounds Read).
Remote attackers can exploit this vulnerability to disclose sensitive information, but exploitation requires user interaction, such as the target visiting a malicious web page or opening a malicious file. While primarily enabling information disclosure, attackers can leverage this issue in conjunction with other vulnerabilities to achieve arbitrary code execution in the context of the affected process.
