CVE-2025-69210 in facturascripts
Summary
by MITRE • 12/30/2025
FacturaScripts is open-source enterprise resource planning and accounting software. Prior to version 2025.7, a stored cross-site scripting (XSS) vulnerability exists in the product file upload functionality. Authenticated users can upload crafted XML files containing executable JavaScript. These files are later rendered by the application without sufficient sanitization or content-type enforcement, allowing arbitrary JavaScript execution when the file is accessed. Because product files uploaded by regular users are visible to administrative users, this vulnerability can be leveraged to execute malicious JavaScript in an administrator’s browser session. Version 2025.7 fixes the issue.

The vulnerability identified as CVE-2025-69210 affects FacturaScripts, an open-source enterprise resource planning and accounting platform that serves as a comprehensive business management solution. This security flaw resides within the file upload functionality of the application, specifically targeting the handling of XML files that users can submit to the system. The vulnerability represents a critical security weakness that undermines the integrity of the application's data processing mechanisms and exposes users to potential malicious exploitation.
The technical implementation of this vulnerability stems from insufficient input validation and sanitization within the file upload module. When authenticated users upload XML files, the system fails to properly validate the content type or sanitize the file contents before rendering them in the user interface. This stored XSS vulnerability allows attackers to embed malicious JavaScript code within XML files that are subsequently executed when the files are accessed by other users. The flaw is particularly concerning because the application's architecture permits regular users to upload files that become visible to administrative users, creating a direct pathway for privilege escalation through session hijacking.
The operational impact of this vulnerability extends beyond simple data corruption or display manipulation. Attackers can leverage this weakness to execute arbitrary JavaScript code within the browser context of administrative users, potentially leading to complete session compromise, data exfiltration, or further lateral movement within the application environment. The stored nature of this vulnerability means that malicious payloads persist in the system and can affect multiple users over time, making it particularly dangerous in multi-user environments where administrative privileges are involved. This vulnerability directly maps to CWE-79 which categorizes cross-site scripting flaws, and aligns with ATT&CK technique T1566.001 for initial access through malicious file uploads.
Mitigation strategies for this vulnerability should focus on immediate implementation of proper input validation and content-type enforcement mechanisms. Organizations should ensure that all file uploads undergo rigorous sanitization processes that strip or encode potentially dangerous content, particularly JavaScript code and executable elements. The fix implemented in version 2025.7 addresses this by introducing proper content validation and sanitization routines that prevent the execution of malicious scripts during file rendering. Additionally, administrators should implement strict access controls and monitoring of file upload activities, while regular security audits should verify that all user-uploaded content is properly validated before being processed or displayed. The vulnerability also underscores the importance of principle of least privilege implementation, where user upload capabilities should be restricted and monitored to prevent abuse.
