CVE-2019-10123 in ESEL-Server 67
Summary
by MITRE
SQL Injection in Advanced InfoData Systems (AIS) ESEL-Server 67 (which is the backend for the AIS logistics mobile app) allows an anonymous attacker to execute arbitrary code in the context of the user of the MSSQL database. The default user for the database is the 'sa' user.

The vulnerability identified as CVE-2019-10123 represents a critical SQL injection flaw within the Advanced InfoData Systems (AIS) ESEL-Server 67 component, which serves as the backend infrastructure for the AIS logistics mobile application. This vulnerability exists in the server-side processing of user inputs, specifically within the database interaction layer where unvalidated input parameters are directly incorporated into SQL query constructions without proper sanitization or parameterization mechanisms. The flaw affects the MSSQL database backend system and exposes a fundamental weakness in input validation and query construction practices that has been classified under CWE-89, which specifically addresses SQL injection vulnerabilities in software systems.
The technical exploitation of this vulnerability enables an anonymous attacker to inject malicious SQL code through improperly validated input fields within the ESEL-Server 67 application. When the application processes these malicious inputs, the SQL injection payload gets executed within the context of the database user account, which by default is configured as the 'sa' (system administrator) account for the MSSQL database. This privileged account access provides the attacker with extensive capabilities including but not limited to data extraction, modification, or deletion of database contents, potential privilege escalation within the database environment, and possible lateral movement within the network infrastructure depending on the database server's access controls and network configuration.
The operational impact of this vulnerability extends beyond simple data compromise as it represents a severe threat to the overall security posture of organizations utilizing AIS logistics solutions. The default 'sa' user account configuration creates a particularly dangerous scenario where any successful exploitation immediately grants the attacker administrative privileges over the entire database system. This vulnerability aligns with ATT&CK technique T1071.005, which covers application layer protocol usage, and T1046, network service scanning, as exploitation typically involves reconnaissance and targeting of the database server. Organizations using this system face risks of complete database compromise, data breaches, and potential system-wide infiltration that could affect supply chain operations and logistics management systems.
Mitigation strategies for CVE-2019-10123 should prioritize immediate implementation of proper input validation and parameterized query construction techniques to prevent SQL injection attacks. The most effective remediation involves updating the ESEL-Server 67 software to the patched version provided by Advanced InfoData Systems, as this addresses the root cause of the vulnerability. Additionally, organizations should implement database access controls by changing the default 'sa' account password, disabling unnecessary database accounts, and implementing principle of least privilege access. Network segmentation and firewall rules should be configured to restrict direct database access from untrusted networks, while database auditing and monitoring should be enabled to detect suspicious activities. The vulnerability also highlights the importance of regular security assessments and penetration testing to identify similar injection vulnerabilities in legacy systems, particularly those that have not received regular security updates or patches.
