In this lab, i learned about the flaw of web application and how it is exploited. Beside that, we learn exploit web application vulnerabilities and prevention method that can be taken to overcome web
application vulnerabilities. Vulnerabilities is intersection of three elements.That is a system susceptibility or flaw, attacker access to the flaw, and attacker capability to exploit the flaw.
Many application employ a tiered architecture and a failure to different tiers properly often leaves an application vulnerable. So it enable the attacker who has found a defect in one component to quickly compromises the entire. When threats arises in shared hosting environment, defects and malicious code in one application can sometimes be exploited to compromise the environment itself and other applications running within it.

Sometimes this vulnerabilities always target the web server that running. This vulnerabilities in web server are broadly composed of defects in their configuration and security flaws within the web server software.

A few reason why vulnerabilities occured is complex systems so the probability of flaws increase, peopele like using common, well-known code, software, operating systems, and/or hardware increases the probability an attacker has or can find the knowledge and tools to exploit the flaw
, more physical connections, privileges, ports, protocols, and services and time each of those are accessible increase vulnerability, weak password, the fundamental operating system design flaws, internet Website Browsing, Software bugs, Unchecked user input and so on. (wikipedia website)
