for filter circumvention did not uncover any methods to successfully achieve Remote Code Execution. All enumerated endpoints were investigated for bypasses of the described protections without success success in a form of a compromise. • Quite a few of the mentioned endpoints allow execution of the SQL statements either as the Database administrator or the Application user. The testers sought to escalate In this realm, it is possible to supply additional Vitess runtime options during the execution of the SQL statements via special ‘/*vt+’ directives; nothing particularly wrong with those extensions
