Jsp servlet url rewriting asp

This seems to be a popular theme on IIS.

A CSRF attack works because browser requests automatically include any credentials associated with the site, such as the user's session cookie, IP address, etc.

Therefore, if the user is authenticated to the site, the site cannot distinguish between the forged or legitimate request sent by the victim. The impact of a successful CSRF attack is limited to the capabilities exposed by the vulnerable application.

Impacts of successful CSRF exploits vary greatly based on the privileges of each victim. When targeting a normal user, a successful CSRF attack can compromise end-user data and their associated functions. If the targeted end user is an administrator account, a CSRF attack can compromise the entire web application.

The task then executes with or without the user's knowledge, either directly or by using a Cross-Site Scripting flaw. For example, see Samy MySpace Worm. However, any cross-site scripting vulnerability can be used to defeat all CSRF mitigation techniques available in the market today except mitigation techniques that involve user interaction and described later in this cheatsheet.

This is because an XSS payload can simply read any page on the site using an XMLHttpRequest direct DOM access can be done, if on same page and obtain the generated token from the response, and include that token with a forged request. If for any reason you violate, you would also need to protect those resources, which is mostly achieved with default form tag [GET method], href, and src attributes.

As a defense-in-depth measure, consider implementing one mitigation from Defense in Depth Mitigations section you can choose the mitigation that fits your ecosystem considering the issues mentioned under them.

These defense-in-depth mitigation techniques are not recommended to be used by themselves without token based mitigation for mitigating CSRF in your applications. You can select any algorithm per your organizational needs.

Strict key rotation and token lifetime policies should be maintained. Policies can be set according to your organizational needs. Synchronizer Token Pattern Any state changing operation requires a secure random token e.

About this task

A CSRF token should be unique per user session, large random value, and also generated by a cryptographically secure random number generator. The server rejects the requested action if the CSRF token fails validation. In order to facilitate a "transparent but visible" CSRF solution, developers are encouraged to adopt a pattern similar to Synchronizer Token Pattern The original intention of this synchronizer token pattern was to detect duplicate submissions in forms.

The synchronizer token pattern requires the generation of random "challenge" tokens that are associated with the user's current session. These challenge tokens are then inserted within the HTML forms and calls associated with sensitive server-side operations. It is the responsibility of the server application to verify the existence and correctness of this token.

By including a challenge token with each request, the developer has a strong control to verify that the user actually intended to submit the desired requests.

Inclusion of a required security token in HTTP requests associated with sensitive business functions helps mitigate CSRF attacks as successful exploitation assumes the attacker knows the randomly generated token for the target victim's session.

This is analogous to the attacker being able to guess the target victim's session identifier. The following describes a general approach to incorporate challenge tokens within the request.

The value of this token must be randomly generated such that it cannot be guessed by an attacker. Consider leveraging the java.

SecureRandom class for Java applications to generate a sufficiently long random token. Alternative generation algorithms include the use of bit BASE64 encoded hashes.The following is a sample file that can be used in IIS6 managed handler configurations. It will prepare IIS6 to send jsp and cfm requests to tomcat via the connector.

Update: We recently launched a service that significantly helps you understand, troubleshoot, and improve IIS and benjaminpohle.com web benjaminpohle.com you regularly troubleshoot IIS errors, manage Windows Servers, or tune benjaminpohle.com performance, definitely check out the demo at benjaminpohle.com when we look at the long history of media darlings, all gift wrapped for us, be they Glen Greenwald, or names like Pilger or Assange, we peek behind the curtain for handlers and may well safely assume they are all “CIA thugs” of one type or another.

The following is a sample file that can be used in IIS6 managed handler configurations. It will prepare IIS6 to send jsp and cfm requests to tomcat via the connector. benjaminpohle.com is the site of veteran server troubleshooter Charlie Arehart, who serves the community with consulting, tuning, and configuration support and training.

He's also a frequent author and speaker. Here you'll find such resources as his blog, past articles and presentations, UGTV, CF, and more. Usually, we use a servlet container such as Tomcat or Jetty to deploy and run our web application separately.

While using Spring Boot it includes an embedded tomcat and all you have to do is, a Maven build that converts your whole application into an executable jar.
