Summary
by MITRE • 10/03/2025
A stored Cross-Site Scripting (XSS) vulnerability has been discovered in Emlog Pro 2.5.19. The vulnerability exists due to insufficient validation of SVG file uploads in the /admin/media.php component, allowing attackers to upload malicious SVG files containing JavaScript code that executes when the uploaded file is viewed.

The stored cross-site scripting vulnerability identified as CVE-2025-60448 represents a critical security flaw in Emlog Pro version 2.5.19 that undermines the application's defensive mechanisms against malicious content injection. This vulnerability specifically targets the media file upload functionality within the administrative interface, creating a persistent threat vector that can be exploited by attackers to compromise user sessions and execute unauthorized commands. The flaw stems from inadequate input sanitization and validation processes that fail to properly inspect or filter SVG file content, allowing malicious actors to embed executable JavaScript code within otherwise legitimate media uploads.
The technical implementation of this vulnerability leverages the inherent characteristics of SVG (Scalable Vector Graphics) files which can contain embedded scripting elements and external references that execute when rendered by web browsers. When an attacker uploads a malicious SVG file through the /admin/media.php component, the application stores the file without sufficient validation of its content structure. The vulnerability operates at the intersection of web application security and file upload validation, where SVG files are treated as safe media assets but can contain JavaScript execution contexts that bypass traditional security filters. This represents a classic case of insufficient data validation and sanitization that aligns with CWE-79 (Cross-Site Scripting) and CWE-20 (Improper Input Validation) classifications within the Common Weakness Enumeration framework.
The operational impact of this vulnerability extends beyond simple script execution, as it creates a persistent threat that can affect multiple users who view the malicious content within the application's media gallery or administrative interface. When victims access pages containing the compromised SVG files, their browsers execute the embedded JavaScript code, potentially leading to session hijacking, credential theft, or redirection to malicious sites. Attackers can leverage this vulnerability to establish persistent backdoors, harvest user credentials, or perform additional attacks through the compromised sessions. The stored nature of this XSS flaw means that the malicious code remains active even after the initial upload, creating a long-term threat that can be exploited repeatedly by different users without requiring additional upload attempts.
Security professionals should consider this vulnerability in the context of the MITRE ATT&CK framework, particularly within the T1566 (Phishing) and T1059 (Command and Scripting Interpreter) techniques, where attackers can use stored XSS to execute malicious scripts and establish footholds within target environments. The vulnerability's exploitation requires minimal privileges since it targets the administrative upload functionality, making it particularly dangerous for content management systems where administrators have elevated access rights. Organizations should implement immediate mitigations including strict SVG content validation, removal of JavaScript execution capabilities from SVG files, and comprehensive input sanitization processes. Additionally, network-based security controls such as web application firewalls and content filtering systems should be configured to detect and block suspicious SVG file patterns, while regular security audits should verify that all file upload mechanisms properly validate content integrity and prevent malicious code execution.
