The vulnerability identified as CVE-2018-7767 resides within Schneider Electric U.motion Builder software prior to version 1.3.4, specifically within the editobject.php script. This represents a critical security flaw that exposes the application to unauthorized data manipulation through malicious input processing. The affected software is widely used in industrial automation environments for configuring and managing building automation systems, making it a potentially significant target for attackers seeking to compromise industrial control systems.
The technical flaw manifests as a SQL injection vulnerability in the SQLite database query processing where the type input parameter is not properly sanitized or validated before being incorporated into database operations. This allows an attacker to inject malicious SQL code through the type parameter, potentially enabling unauthorized access to the underlying database structure. The vulnerability stems from inadequate input validation and parameterized query construction, which are fundamental security practices that should prevent such injection attacks. According to CWE classification, this corresponds to CWE-89 SQL Injection, a well-documented weakness that has been consistently ranked among the top security risks in the OWASP Top Ten.
The operational impact of this vulnerability extends beyond simple data theft or manipulation, particularly in industrial control environments where U.motion Builder is deployed. An attacker who successfully exploits this vulnerability could potentially gain unauthorized access to the database containing configuration information, user credentials, or other sensitive operational data. The implications are particularly concerning in building automation contexts where system integrity and security are paramount for maintaining safe and efficient operations. The vulnerability could enable attackers to modify system configurations, escalate privileges, or even disrupt building automation services that rely on the integrity of the underlying database.
Mitigation strategies for this vulnerability should focus on immediate software updates to version 1.3.4 or later, which would contain the necessary patches to address the SQL injection flaw. Organizations should also implement network segmentation to limit access to the affected systems and ensure that only authorized personnel can interact with the U.motion Builder software. Additionally, implementing proper input validation and parameterized queries in the application code would serve as defensive measures against similar vulnerabilities. From an ATT&CK framework perspective, this vulnerability aligns with techniques such as T1071.004 Application Layer Protocol and T1190 Exploit Public-Facing Application, highlighting the need for proper application security controls and regular vulnerability assessments. Organizations should also consider implementing database activity monitoring and access controls to detect and prevent unauthorized database access attempts. The vulnerability underscores the importance of secure coding practices and regular security updates in industrial control systems where the stakes of security breaches can be particularly high.
