injections are very well researched when it comes to MSSQL and Oracle. But in MySQL I noticed that this topic is not well researched. I thought of researching about this topic based on my experiences in SQL injections. For this purpose we can take advantage of functions such as load_file() and select … into outfile/dumpfile. Apart from that we can also steal NetNTLM hashes and perform SMB relay attacks. All this is possible only in MySQL under Windows.
What is Out-of-Band Injection?
These attacks involve in alternative channels to extract data from the server. It might be HTTP(S) requests, DNS resolutions, file systems, E-mails, etc depending on the functionality of the back-end technology.
