Cross Site Scripting

Understanding the vulnerability and payload

Cross Site Scripting:

1) Is a type of web application software vulnerability

2) It allows code injection by malicious web users into the web pages viewed by other users.

3) An exploited cross-site scripting vulnerability can be used by attackers to bypass access controls and gain access to unauthroized resources.

Application Security Training can help you protect your applications from malicious hackers.

Security measures built into applications and a sound application security routine minimize the likelihood that hackers will be able to manipulate applications and access, steal, modify, or delete sensitive data. Once an afterthought in software design, security is becoming an increasingly important concern during development as applications become more frequently accessible over networks and are, as a result, vulnerable to a wide variety of threats.

Actions taken to ensure application security are sometimes called countermeasures. The most basic software countermeasure is an application firewall that limits the execution of files or the handling of data by specific installed programs. The most common hardware countermeasure is a router that can prevent the IP address of an individual computer from being directly visible on the Internet. Other countermeasures include conventional firewalls, encryption/decryption programs, anti-virus programs, spyware detection/removal programs, and biometric authentication systems

Networks still face many challenges but advancements in network security have made networks less exploitable. As networks become more secure, the comparatively insecure application layer becomes an attractive target for hackers. These are just a few of the exploitable vulnerabilities and attack methods common to applications at InfoSec Institute.
* SQL injection

* Cross-site scripting (XSS) This flaw has become the most popular among attackers, according to a recent study

* Buffer overflow

* Data Recovery InfoSec Institute

* Directory traversal

* Denial of Service (DoS)

* Man-in-the-middle

* Session hijacking
