This lets the attacker add extra headers to HTTP responses or even make the browser ignore the original content and process injected content instead.

The attacker can terminate legitimate content prematurely, inject their own headers, and inject new content that includes JavaScript. Therefore, CRLF injections may be very dangerous. Read more about cross-site scripting XSS and its potential consequences. The most efficient way to detect CRLF injections is by using an automated web vulnerability scanner, for example, Acunetix.

You can, of course, also find them manually through manual penetration testing, but it consumes much more time and resources. Acunetix will find many different types of vulnerabilities for you. See what Acunetix Premium can do for you. You can also encode the data that you pass into HTTP headers. Read more about the principles of building secure code.

Closing this question glosses over fundamental differences between the questions and perpetuates misinformation. AdrianMcCarthy It's a problem with the way close votes act as answers in a way; an answer claiming the two were the same could be downvoted and then greyed out as very, very wrong, but it only takes 4 agreeing votes comparable to upvotes to have a very wrong close happen, with no way to counter the vote until after it's happened.

This formulation of the question is admittedly better, but it is still for all practical purposes the same question. Korpela: No, it really isn't. Show 2 more comments. Active Oldest Votes.

The superior LFCR option is sadly missing. Flimm yes, backslash is the commonly designated character to "escape" what follows it.

Manu Manu Even today we can still see this mechanical logic in any inktjet-printer I love to understand since I hate to learn. My other memory-tricks are: "mac? That's not what it says. Adrian Will you take persona experience?

Adrian 2 Don't forget, this was in the electro-mechanical era, where each character did exactly one function.

Five data bits, between one start bit and one-and-a-half stop bits. How can you have half a bit? By waiting half a bit time before starting to send the next character, to give the print head time to return to center.
