This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. Authentication is not required to exploit this vulnerability.

The specific flaw exists within the DBVisitor.dll component. Multiple SOAP requests implemented by the component are vulnerable to SQL Injection. These flaws allow an attacker to execute arbitrary SQL statements in the context of the web service and to exfiltrate data (including the account names and password hashes) from the vulnerable product.
