CVE-2021-40850Network attack vector

Unauthenticated database compromise via web service SQL injection

Published Dec 17, 2021 · Updated Sep 16, 2024

SQL injection in TCMAN GIM 8.0 and 11.0 allows remote attackers to compromise database data through crafted web service requests. Several methods in /PC/WebService.asmx incorporate request-controlled input into database queries without neutralizing SQL syntax, although the affected methods and parameters are undisclosed. No authentication or user interaction is required; the published impact assessment covers database disclosure, modification, and service interruption.
