CVE-2025-41407 is a high-severity SQL Injection vulnerability (CWE-89) identified in Zoho Corporation's ManageEngine ADAudit Plus product, specifically affecting versions below 8511. The vulnerability exists in the OU (Organizational Unit) History report feature, where improper neutralization of special elements in SQL commands allows an attacker with at least low privileges (PR:L) to inject malicious SQL code. The vulnerability has a CVSS v3.1 base score of 8.3, indicating a high impact on confidentiality and integrity, with a low impact on availability. The attack vector is network-based (AV:N), requiring no user interaction (UI:N), and the scope remains unchanged (S:U). Exploitation could allow an attacker to access, modify, or exfiltrate sensitive data stored in the backend database, potentially leading to unauthorized disclosure of audit logs or other critical information. Although no known exploits are currently reported in the wild, the vulnerability's nature and ease of exploitation (low attack complexity) make it a significant risk. The lack of available patches at the time of publication emphasizes the need for immediate mitigation efforts. Given that ADAudit Plus is widely used for auditing and monitoring Active Directory environments, exploitation could undermine the integrity of security monitoring and compliance reporting.

For European organizations, the impact of this vulnerability is substantial. ADAudit Plus is commonly deployed in enterprises and public sector organizations to monitor Active Directory changes, user activities, and security events. Successful exploitation could lead to unauthorized access to sensitive audit data, compromising the confidentiality and integrity of security logs. This could hinder incident response, compliance with GDPR and other regulatory frameworks, and potentially allow attackers to cover their tracks by modifying audit records. The vulnerability could also be leveraged as a foothold for further lateral movement within the network, increasing the risk of broader compromise. Given the critical role of ADAudit Plus in security operations, European organizations relying on this tool face increased risk of data breaches and regulatory penalties if the vulnerability is exploited.

1. Immediate upgrade to ManageEngine ADAudit Plus version 8511 or later once available, as this will contain the official patch addressing the SQL injection vulnerability. 2. Until patching is possible, restrict network access to the ADAudit Plus web interface to trusted IP addresses and internal networks only, minimizing exposure to potential attackers. 3. Implement Web Application Firewall (WAF) rules to detect and block SQL injection attempts targeting the OU History report endpoints. 4. Conduct thorough audit and monitoring of ADAudit Plus logs for unusual query patterns or access anomalies that could indicate exploitation attempts. 5. Review and enforce the principle of least privilege for ADAudit Plus user accounts, ensuring that only necessary users have access to the vulnerable functionality. 6. Engage in proactive vulnerability scanning and penetration testing focused on ADAudit Plus to identify any signs of exploitation or related weaknesses. 7. Prepare incident response plans specifically addressing potential compromise of audit data and ensure backups of audit logs are securely maintained and regularly tested for integrity.
