CVE-2025-49484 is a SQL injection vulnerability classified under CWE-89, found in the JS Jobs component for Joomla versions 1.0.0 through 1.4.1. The vulnerability arises from improper neutralization of special elements in SQL commands, specifically through the 'cvid' parameter used in the employee application feature. Low-privilege users can exploit this flaw to inject arbitrary SQL commands, potentially allowing unauthorized data access, data modification, or disruption of service. The CVSS 4.0 score of 8.7 reflects the vulnerability's high impact and ease of exploitation, as it requires no user interaction and no elevated privileges beyond low-level access. The vulnerability affects the confidentiality, integrity, and availability of the underlying database and web application. Although no public exploits have been reported yet, the nature of SQL injection vulnerabilities makes them prime targets for attackers. Joomla websites using the JS Jobs component for recruitment or job listing functionalities are at risk, especially if they have not updated to patched versions. The lack of available official patches at the time of publication necessitates immediate attention to alternative mitigation strategies such as input validation, use of prepared statements, or disabling the vulnerable feature temporarily.

For European organizations, this vulnerability poses a significant risk to the security of their Joomla-based job portals and recruitment platforms. Exploitation could lead to unauthorized disclosure of sensitive applicant data, manipulation or deletion of job listings, and potential defacement or downtime of websites. This could result in reputational damage, regulatory penalties under GDPR due to data breaches, and operational disruptions. Organizations relying on the JS Jobs component for critical HR functions may face business continuity challenges. The vulnerability's exploitation could also serve as a foothold for further network intrusion or lateral movement within corporate environments. Given the high adoption of Joomla in Europe and the importance of online recruitment, the impact is amplified in sectors such as public administration, large enterprises, and recruitment agencies. The absence of known exploits currently provides a window for proactive mitigation before widespread attacks occur.

1. Immediately upgrade the JS Jobs component to a version beyond 1.4.1 once an official patch is released by joomsky.com or Joomla maintainers. 2. Until a patch is available, implement strict input validation and sanitization on the 'cvid' parameter to block malicious SQL payloads. 3. Employ parameterized queries or prepared statements in the application code to prevent SQL injection. 4. Restrict access to the employee application feature to trusted users or IP ranges where feasible. 5. Monitor web server and database logs for unusual or suspicious SQL queries targeting the 'cvid' parameter. 6. Conduct regular security audits and penetration testing focused on Joomla components and plugins. 7. Consider temporarily disabling the JS Jobs component if it is not critical to operations. 8. Educate development and IT teams about secure coding practices and the risks of SQL injection. 9. Deploy Web Application Firewalls (WAFs) with rules specifically designed to detect and block SQL injection attempts targeting Joomla plugins. 10. Maintain up-to-date backups of affected systems to enable rapid recovery in case of compromise.
