CVE-2025-32466 is a medium-severity SQL Injection vulnerability affecting the RSMediaGallery component versions 1.7.4 through 2.1.7 for the Joomla content management system. The vulnerability arises due to improper neutralization of special elements in SQL commands (CWE-89) within the dashboard component of RSMediaGallery. Specifically, user-supplied input is not adequately sanitized before being stored and rendered. This flaw allows an attacker to inject malicious JavaScript code into text fields or other input points. When a user with access to the dashboard views the crafted input, the injected JavaScript executes in their browser context, effectively combining SQL injection with a stored cross-site scripting (XSS) attack vector. The CVSS 4.0 score is 6.7, reflecting a medium severity with network attack vector, low attack complexity, no privileges required, but user interaction needed and high impact on confidentiality. The vulnerability does not appear to have known exploits in the wild yet, and no patches have been linked at the time of publication. The issue is critical because it can lead to unauthorized data access or manipulation via SQL injection, and also session hijacking or further compromise through the XSS payload execution in privileged users' browsers. Given that Joomla is widely used for website content management, and RSMediaGallery is a popular media gallery extension, this vulnerability could be leveraged to compromise websites that use these versions of the component, especially those with multiple users accessing the dashboard.

For European organizations, this vulnerability poses a significant risk especially to those relying on Joomla-based websites with the RSMediaGallery component installed. Successful exploitation could lead to unauthorized disclosure or modification of sensitive data stored in the backend databases, undermining confidentiality and integrity. The injected JavaScript executed in the dashboard users’ browsers could facilitate session hijacking, privilege escalation, or deployment of further malware, potentially leading to full site compromise. This is particularly concerning for organizations handling personal data subject to GDPR, as data breaches could result in regulatory penalties and reputational damage. Additionally, websites serving as customer portals, intranets, or content management platforms could face operational disruptions. The requirement for user interaction (dashboard user clicking the crafted text) somewhat limits automated exploitation but does not eliminate risk, especially in environments with multiple administrators or editors. The medium CVSS score reflects these factors but the combined SQL injection and stored XSS vector increases the threat level beyond typical SQL injection alone.

1. Immediate mitigation should involve upgrading the RSMediaGallery component to a version where this vulnerability is patched once available. Since no patch links are currently provided, organizations should monitor vendor advisories closely. 2. As a temporary measure, restrict dashboard access to trusted users only and enforce strict user permissions to minimize exposure. 3. Implement Web Application Firewall (WAF) rules tailored to detect and block SQL injection patterns and suspicious input targeting the dashboard component. 4. Conduct input validation and sanitization on all user inputs at the application level, especially for text fields in the dashboard, to neutralize special characters before storage. 5. Enable Content Security Policy (CSP) headers to reduce the impact of any injected JavaScript by restricting script execution sources. 6. Regularly audit Joomla extensions for vulnerabilities and remove or replace unsupported or unmaintained components. 7. Educate administrators and users with dashboard access about the risk of clicking on untrusted or unexpected content within the dashboard interface. 8. Monitor logs for unusual database queries or dashboard activity that could indicate attempted exploitation.
