CVE-2026-3785 identifies a SQL injection vulnerability in EasyCMS, a content management system, affecting all versions up to 1.6. The vulnerability resides in an unspecified function within the /RbacnodeAction.class.php file, part of the Request Parameter Handler component. The attack vector involves manipulation of the _order parameter, which is improperly sanitized before being used in SQL queries. This improper input validation enables remote attackers to inject arbitrary SQL commands, potentially leading to unauthorized data access, data modification, or database compromise. The vulnerability can be exploited remotely without requiring authentication or user interaction, increasing its risk profile. The CVSS 4.0 base score is 5.3 (medium severity), reflecting the ease of exploitation and moderate impact on confidentiality, integrity, and availability. Despite public availability of an exploit, no active exploitation has been confirmed. The vendor has not issued a patch or responded to disclosure, leaving users exposed. The lack of a patch necessitates that users apply alternative mitigations such as input filtering, web application firewalls, and monitoring for suspicious database activity. This vulnerability highlights the critical need for secure coding practices and timely vendor response in CMS platforms.

The SQL injection vulnerability in EasyCMS can have significant impacts on organizations using this CMS. Successful exploitation could allow attackers to bypass authentication controls, retrieve sensitive data such as user credentials or proprietary content, modify or delete database records, and potentially escalate privileges within the CMS environment. This compromises the confidentiality, integrity, and availability of the affected systems. Given that EasyCMS is used to manage web content, exploitation could lead to website defacement, data breaches, or further pivoting into internal networks. The remote and unauthenticated nature of the exploit increases the attack surface, making it easier for attackers to target vulnerable installations. The absence of vendor patches prolongs exposure, increasing the window of opportunity for attackers. Organizations relying on EasyCMS may face reputational damage, regulatory penalties, and operational disruptions if exploited.

1. Implement strict input validation and sanitization on the _order parameter at the web application or proxy level to block malicious SQL payloads. 2. Deploy a Web Application Firewall (WAF) with rules specifically designed to detect and block SQL injection attempts targeting EasyCMS parameters. 3. Restrict database user permissions to the minimum necessary, preventing unauthorized data manipulation even if injection occurs. 4. Monitor database logs and web server logs for unusual queries or access patterns indicative of SQL injection attempts. 5. Isolate EasyCMS installations in segmented network zones to limit lateral movement if compromised. 6. Consider migrating to alternative CMS platforms with active security support if vendor patching remains unavailable. 7. Regularly back up CMS data and test restoration procedures to mitigate data loss from potential attacks. 8. Engage in threat intelligence sharing to stay informed about emerging exploits targeting EasyCMS. 9. If feasible, conduct code audits and apply manual patches or input filtering in the affected PHP files until official fixes are released.
