The vulnerability identified as CVE-2018-7765 resides within Schneider Electric U.motion Builder software, specifically in the track_import_export.php component that handles data import and export operations. This flaw affects versions prior to v1.3.4 and represents a critical security weakness that could enable unauthorized access to sensitive operational data. The vulnerability stems from improper input validation within the software's database interaction layer, where user-supplied parameters are directly incorporated into SQL queries without adequate sanitization or parameterization.
The technical implementation of this vulnerability manifests through the object_id input parameter which is processed within an SQLite database query. When an attacker provides malicious input through this parameter, the software fails to properly escape or validate the data before incorporating it into the database command. This creates an environment where SQL injection attacks can be executed, potentially allowing attackers to manipulate database operations, extract confidential information, or even execute arbitrary commands on the underlying system. The vulnerability is classified as a classic SQL injection flaw that operates at the database interface level where user input directly influences query construction.
The operational impact of CVE-2018-7765 extends beyond simple data compromise, particularly within industrial control environments where Schneider Electric U.motion Builder is commonly deployed. Attackers could exploit this vulnerability to access sensitive operational data including project configurations, user credentials, and system parameters that are crucial for maintaining industrial process integrity. The implications are particularly severe in environments where operational technology systems are connected to corporate networks, as successful exploitation could provide attackers with a foothold for lateral movement and potentially lead to disruption of critical industrial processes. This vulnerability affects the confidentiality and integrity of industrial control system data, making it a significant concern for organizations operating in critical infrastructure sectors.
Organizations should prioritize immediate remediation by upgrading to Schneider Electric U.motion Builder version 1.3.4 or later, which includes proper input validation and parameterization of database queries. Additional mitigations include implementing network segmentation to limit access to affected systems, deploying web application firewalls to detect and block malicious SQL injection attempts, and conducting thorough input validation reviews for all database interaction points. The vulnerability aligns with CWE-89 which specifically addresses SQL injection flaws, and represents a technique commonly mapped to ATT&CK tactic TA0006 (Credential Access) and TA0005 (Defense Evasion) where attackers leverage database vulnerabilities to extract credentials or manipulate system data. Security teams should also consider implementing database activity monitoring and regular vulnerability assessments to identify similar weaknesses in other industrial control system components.
