Despite the same source policy and other security measures, cyber criminals have found ways to use session cookies to bypass the policy. This is because each time you open the browser, a session cookie is created to confirm that it is a web site user and allow you to move seamlessly from one page to another. The
Session cookies store login credentials (including WordPress sites), credit card information, shipping details, and other sensitive data. The working principle is as follows: For example, you would like to log in to an online bank account. When the web site is opened, a session cookie is created. If it is not a session cookie, you must log in to your online bank account every time you switch pages. It is not uncommon for a user’s browser to have a vulnerability. If present, the cyber criminal will use the code inserted into the user input to steal the session cookie. In this way, hackers can steal cookies on all websites opened in the user’s browser. You can then use these cookies to log in to a user account, pretend to be a user and steal financial data. The
Why is cross site scripting dangerous? Inter site scripting is one of the most common high-risk word press vulnerabilities. Unlike other security vulnerabilities, XSS attacks are very common because they are very complex to resolve. Even with built-in protection, it is easy to make mistakes, making cross site scripting possible. In the HTML or JavaScript of a web page, a single error may make the website vulnerable to scripting attacks between sites. Male attackers find ways to maliciously exploit XSS vulnerabilities, which can steal account vouchers and financial data, and facilitate phishing fraud. They can also spread computer worms or remotely access users’ computers. In addition, through XSS attacks, hackers can: The
XSS attacks that search for and exploit computer controlled intranet applications by remotely spreading malicious code in user accounts are generally considered more dangerous than SQL injection. However, combined with social engineering, scripts between websites can enable cyber criminals to perform highly dangerous intelligent attacks, including Trojan horse implantation, key recording, phishing, ID theft and forgery of requests between websites. To counter XSS attacks, large IT companies will launch a special error reporting program. These programs are implemented in many organizations and provide compensation or recognition for users who report XSS vulnerabilities in scripts. In this way, the company is investing in network security to allow other developers to identify errors. Google has also launched a game to practice sending XSS bugs. The
Male XSS attack type cross site script attacks have three main types: reflection, storage and DOM based XSS. To better understand how XSS works, let’s look at each type of XSS vulnerability. XSS vulnerability (persistent or type I) saved by saved cross site scripts occurs when user input is stored in a database, comment field, visitor log, or other target server. Victims can then search the data stored in the web application (rendering unsafe data in the browser). In this way, when a hacker performs an attack, the XSS filter of the browser will not display the payload. If the victim visits the affected page, the payload may be accidentally triggered. The
The XSS vulnerability reflected by the reflected cross site script (also known as non persistent or type II) occurs when a web application immediately returns user input from search results, error messages, or other responses. In this case, the user input data will not be saved, but reflected. Hackers can insert malicious XSS scripts. Different from the saved XSS, the reflected XSS
