Description

An SQL injection vulnerability in Advantech iView 5.7.04.6469. The specific flaw exists within the ConfigurationServlet endpoint, which listens on TCP port 8080 by default. An unauthenticated remote attacker can craft a special column_value parameter in the setConfiguration action to bypass checks in com.imc.iview.utils.CUtils.checkSQLInjection() to perform SQL injection. For example, the attacker can exploit the vulnerability to retrieve the iView admin password.

• CWE-89Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
