CVE-2025-63694 identifies an SQL Injection vulnerability in DzzOffice version 2.3.7 and earlier, specifically within the explorer/groupmanage functionality. SQL Injection vulnerabilities occur when untrusted input is improperly sanitized and directly incorporated into SQL queries, allowing attackers to alter the intended query logic. This can lead to unauthorized data retrieval, modification, or deletion, and in some cases, full system compromise if the database server is leveraged to execute further commands. The affected component, explorer/groupmanage, likely handles group management features, which may include user roles, permissions, or shared resources. Exploiting this vulnerability typically involves an attacker sending specially crafted input to the vulnerable parameter, which the backend database processes without adequate filtering. No CVSS score has been assigned yet, and no public exploits are known, but the vulnerability is published and reserved by MITRE as of late 2025. The absence of patches at the time of reporting suggests organizations must implement interim mitigations such as input validation and database access restrictions. The vulnerability impacts confidentiality and integrity primarily, as attackers could access or alter sensitive group management data. The ease of exploitation is moderate to high since SQL Injection often does not require authentication or complex conditions. The scope is limited to installations of DzzOffice up to version 2.3.7, but given the software’s use in document and group management, the impact can be significant. Organizations should monitor for unusual database activity and prepare for patch application once available.

For European organizations, this vulnerability poses a significant risk to the confidentiality and integrity of sensitive data managed within DzzOffice, particularly in environments handling regulated or personal data subject to GDPR. Unauthorized access or modification of group management data could lead to privilege escalation, unauthorized data disclosure, or disruption of collaboration workflows. Public sector entities, educational institutions, and enterprises using DzzOffice for document and group management are especially vulnerable. The lack of known exploits reduces immediate risk, but the potential for future exploitation remains high. Data breaches resulting from this vulnerability could lead to regulatory penalties, reputational damage, and operational disruptions. Given the critical role of group management in access control, exploitation could cascade into broader system compromise. The vulnerability’s presence in a widely used collaboration platform increases the attack surface across multiple sectors in Europe.

1. Monitor vendor communications closely and apply official patches or updates for DzzOffice as soon as they become available. 2. Implement strict input validation and sanitization on all user-supplied data, especially in the explorer/groupmanage module, to prevent malicious SQL payloads. 3. Restrict database user permissions to the minimum necessary, avoiding use of high-privilege accounts for application database connections. 4. Employ Web Application Firewalls (WAFs) with SQL Injection detection rules tailored to DzzOffice traffic patterns. 5. Conduct regular security audits and penetration testing focusing on injection flaws in web applications. 6. Monitor logs for anomalous database queries or errors indicative of injection attempts. 7. Segment and isolate critical systems to limit lateral movement in case of compromise. 8. Educate developers and administrators on secure coding practices and the risks of SQL Injection. 9. Consider temporary mitigations such as disabling or restricting access to the vulnerable explorer/groupmanage functionality if feasible until patches are applied.
