CVE-2025-0902 is a high-severity vulnerability found in PDF-XChange Editor, specifically within the parsing of XPS files. This vulnerability allows remote attackers to disclose sensitive information on affected installations of the software. User interaction is required for exploitation, as the target must either visit a malicious webpage or open a malicious file.
The specific flaw results from a lack of proper validation of user-supplied data, which can lead to reading past the end of an allocated object. Attackers may leverage this flaw in conjunction with other vulnerabilities to execute arbitrary code within the context of the current process. Given the potential for serious consequences, organizations must address this vulnerability urgently.
The vulnerability has been classified with a CVSS score of 8.8, indicating a high level of severity. This rating reflects the significant risk to organizations, as successful exploitation could lead to data exposure and possible compromise of sensitive information.
Organizations should prioritize patching immediately. With user interaction required for exploitation, awareness and training can also help reduce the risk associated with this vulnerability.
Vulnerability Details
CVE-2025-0902 is classified as an out-of-bounds read information disclosure vulnerability in PDF-XChange Editor. The vulnerability exists due to improper validation of user-supplied data during XPS file parsing. This can result in sensitive information disclosure.
The CVSS score for this vulnerability is 8.8, indicating high severity. The attack vector is classified as network-based, with low complexity and no required privileges. User interaction is required for exploitation, and the impacts on confidentiality, integrity, and availability are all rated as high.
The vulnerability affects all versions of PDF-XChange Editor prior to 10.4.2.390. The specific weakness is classified under CWE-125.
Technical Analysis
The root cause of CVE-2025-0902 stems from the improper validation of user-supplied data during the parsing of XPS files. This vulnerability allows an attacker to read data beyond the allocated buffer, potentially exposing sensitive information stored in memory.
The attack vector is network-based, requiring the target user to either visit a malicious website or open a malicious XPS file. The attack complexity is low, as it does not require any specific conditions or advanced skills to exploit.
No special privileges are required for exploitation, which further increases the risk associated with this vulnerability. User interaction is necessary, as the exploitation relies on the victim engaging with the malicious content.
The confidentiality, integrity, and availability impacts are all rated as high, indicating that successful exploitation can lead to significant breaches of sensitive data and overall system compromise.
Risk & Impact Analysis
Organizations are at significant risk due to CVE-2025-0902, as successful exploitation can lead to unauthorized access to sensitive information. The requirement for user interaction does not significantly mitigate the risk, as phishing attacks and social engineering tactics can be employed to trick users into triggering the vulnerability.
The potential blast radius is substantial, particularly for organizations that utilize PDF-XChange Editor in environments where sensitive data is processed. Given the high CVSS score and the fact that exploitation can lead to serious data breaches, this vulnerability should be addressed in priority patch cycles.
Risk to organizations includes the possibility of data exposure, regulatory fines, and reputational damage. Organizations should conduct risk assessments to evaluate their exposure and implement necessary controls to mitigate the associated risks.
