Is XSS possible via CSS injection?
They are closely related to cross-site scripting (XSS) vulnerabilities but often trickier to exploit. Being able to inject arbitrary CSS into the victim’s browser may enable various attacks, including: Using CSS selectors to read parts of the HTML source, which may include sensitive data such as anti-CSRF tokens.
How does arbitrary code execution work?
When a particular vulnerability allows an attacker to execute “arbitrary code”, it typically means that the bad guy can run any command on the target system the attacker chooses. This could mean that the attacker triggers code already on the box, invoking a program or DLL by exploiting the vulnerability.
What is a CSS injection vulnerability?
