[R1] Advantech WebAccess SQL Injection



Tenable discovered a new authenticated SQL injection vulnerability in Advantech WebAccess while researching the patches for TRA-2017-04. The SQL injection can be found in /WaExlViewer/rmTemplate.aspx in the method deleteTemplateByTemplateName.
public void deleteTemplateByTemplateName(string templateName)
        if (this.conn.State == ConnectionState.Open)
            string cmdText = "DELETE FROM rRptTemplate WHERE TemplateName='" + templateName + "'";
            OleDbCommand oleDbCommand = new OleDbCommand(cmdText, this.conn);
            OleDbDataReader oleDbDataReader = oleDbCommand.ExecuteReader();
    catch (Exception ex)
Furthermore, Tenable realized that the authentication bypass detailed in CVE-2017-5152 was not properly patched. An unauthenticated remote attacker can combine these vulnerabilities to obtain the administrator password for the web interface.
