This is a normal XSS JavaScript injection, and most likely to get caught but I suggest trying it first (the quotes are not required in any modern browser so they are omitted here): Please note that input filtering is an incomplete defense for XSS which these tests can be used to illustrate.

This cheat sheet lists a series of XSS attacks that can be used to bypass certain XSS defensive filters. We wanted to create short, simple guidelines that developers could follow to prevent XSS, rather than simply telling developers to build apps that could protect against all the fancy tricks specified in rather complex attack cheat sheet, and so the OWASP Cheat Sheet Series was born. The very first OWASP Prevention Cheat Sheet, the Cross Site Scripting Prevention Cheat Sheet, was inspired by RSnake's XSS Cheat Sheet, so we can thank RSnake for our inspiration. That site now redirects to its new home here, where we plan to maintain and enhance it. The initial contents of this article were donated to OWASP by RSnake, from his seminal XSS Cheat Sheet, which was at. This article is focused on providing application security testing professionals with a guide to assist in Cross Site Scripting testing.

To encode and decode data with Base64, you can take advantage of the two helper functions atob() and btoa() in Javascript. For example with SAP HANA XS Advanced, you can quickly build an OData service to receive images via JSON. Although there will be a 37 bloat in space requirements, it can be useful to encode images in Base64. When you encode your images in Base64, your images can be transferred and saved as text.

How to Encode Data with Base64 in Javascript How to use Python 3 to convert your images to Base64 encoding.

If you are transferring a big BLOB (Binary Large Object File) across the internet, it’s actually mandatory to encode the data using Base64.
