CVE-2023-52335Network attack vector

Credential disclosure via unvalidated column_value SQL construction

Published Nov 22, 2024 · Updated Dec 5, 2024

SQL injection in ConfigurationServlet in Advantech iView 5.7.04 allows remote attackers to disclose stored credentials. The servlet parses the column_value element and inserts its unvalidated user-supplied string into constructed SQL queries. The servlet listens on TCP port 8080 by default, requires no authentication, and exposes credentials that enable further compromise.
