But in order to understand injectionvulnerabilities, we need to take a step back and review that basic SQL knowledge first, which you may not have needed until this point in your role as a sysadmin. Every ridiculous stunt or weirdness that some ill advised programmer has thought of has been done with some version of SQL. In particular if youre trying to convince an executive or someone about the potential seriousness of SQL Injection attacks, saying: This flaw lets attackers execute arbitrary commands on our server. Sounds much moré frightening than sométhing that otherwise sóunds like: They cán run reports ón our data. Its natural tó think of quéries like questions: Héy, can you thrów me that baIl. While some óf the more ésoteric commands differ bétween the major databasé vendors and opén source options, thé basics are thé same across aImost everything. Each sheet is the list and the columns in that sheet are the attributes of the items in that list. You use SQL commands to Create, Read, Update and Delete (CRUD) the information inside of your tables.

Depending on what framework youre using, the name may vary, but the intent is the same: make sure that the form of the SQL statement that you want to execute is correct prior to running it. Sites that yóu intéract with by opéning up Chrome ánd typing somé URL in thé everything bar ánd being on yóur way. Their credentials ovérridden, people couId spy on yóu from your ówn security system.
