Misconfigured caching can lead to various vulnerabilities. For example, attackers may use badly-configured intermediate servers (reverse proxies, load balancers, or cache proxies) to gain access to sensitive data. Another way to exploit caching is through Web Cache Poisoning attacks. The browser cache may look like…

Session Token in URL Vulnerability
The HTTP protocol and web servers are stateless by nature. This means that there is no way for them to track user activity. The web server treats every request as a new one. For this reason, browsers and web servers need to use session tokens….
Common Injection Attack Types, Examples, Prevention
Injection Attacks Injection attacks refer to a broad class of attack vectors. In an injection attack, an attacker, sometimes with the use of automated hacking software, supplies untrusted input to a program. This input gets processed by an interpreter as part of a command or…
What is Code Injection (Remote Code Execution)
Code Injection or Remote Code Execution (RCE) enables the attacker to execute malicious code as a result of an injection attack. Code Injection attacks are different than Command Injection attacks. Attacker capabilities depend on the limits of the server-side interpreter (for example, PHP, Python, and…
