Description

Advantech iView ConfigurationServlet SQL Injection Information Disclosure Vulnerability. This vulnerability allows remote attackers to disclose sensitive information on affected installations of Advantech iView. Authentication is not required to exploit this vulnerability. The specific flaw exists within the ConfigurationServlet servlet, which listens on TCP port 8080 by default. When parsing the column_value element, the process does not properly validate a user-supplied string before using it to construct SQL queries. An attacker can leverage this vulnerability to disclose stored credentials, leading to further compromise. Was ZDI-CAN-17863.

• 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.
