Advantech WebAccess SQL Injection
An attacker using SQL injection may use arguments to construct queries without proper sanitization. The DBVisitor.dll is exposed through SOAP interfaces, and the exposed functions are vulnerable to SOAP injection. This may allow unexpected SQL action and access to records in the table of the software database or execution of arbitrary code.
