Is cross site request forgery?
Cross-Site Request Forgery (CSRF) is an attack that forces authenticated users to submit a request to a Web application against which they are currently authenticated. CSRF attacks exploit the trust a Web application has in an authenticated user.
Which method can be used to prevent the cross site request forgery?
challenge token
The most popular method to prevent Cross-site Request Forgery is to use a challenge token that is associated with a particular user and that is sent as a hidden value in every state-changing form in the web app.
What are prerequisites for a successful cross site request forgery exploit?
For a CSRF attack to be possible, three key conditions must be in place:
- A relevant action. There is an action within the application that the attacker has a reason to induce.
- Cookie-based session handling.
- No unpredictable request parameters.
Which is an example of cross site request forgery?
Cross-site request forgery (CSRF or XSRF) is an attack that tricks the victim’s browser into performing an unwanted action on the victim’s behalf. For example, this type of attack could result in transferring funds, changing a password, or purchasing an item. For more information about CSRF, see Cross-Site Request Forgery Attack Explained.
SharePoint 2010 prevents developers from performing state-changing operations on a GET request. For example, a Microsoft ASP.NET page is not allowed to update the contents of a list item or web property when the list item or web property is fetched by using a GET.
This list addresses aspects of cross-site scripting (XSS), cross-site request forgery (CSRF or XSRF), elevation of privilege, denial of service, and information disclosure. Cross-site scripting (XSS) attacks exploit vulnerabilities in webpage validation by injecting client-side script code.
What makes an application susceptible to a cross site scripting attack?
Common vulnerabilities that make your web applications susceptible to cross-site scripting attacks include failing to properly validate input, failing to encode output, and trusting the data retrieved from a shared database. The following sections describe these vulnerabilities and provide recommendations.
