Cross-site request forgery, also known as one-click attack or session riding and abbreviated as CSRF (sometimes pronounced sea-surf) or XSRF, is a type of malicious exploit of a website where unauthorized commands are transmitted from a user that the web application trusts. There are many ways in which a malicious website can transmit such commands; specially-crafted image tags, hidden forms, and JavaScript XMLHttpRequests, for example, can all work without the user's interaction or even knowledge. Unlike cross-site scripting (XSS), which exploits the trust a user has for a particular site, CSRF exploits the trust that a site has in a user's browser.

ActiveUS20110154473A1Digital data protectionMultiple digital computer combinationsThird partyCross-site request forgery
The present solution described herein is directed towards systems and methods to prevent cross-site request forgeries based on web form verification using unique identifiers. The present solution tags each form from a server that is served out in the response with a unique and unpredictable identifier. When the form is posted, the present solution enforces that the identifier being returned is the same as the one that was served out to the user. This prevents malicious unauthorized third party users from submitting a form on a user's behalf since they cannot guess the value of this unique identifier that was inserted.

Preventing Cross-Site Request Forgery (CSRF) security attacks on a server in a client-server environment. In one aspect, this comprises embedding a nonce and a script in all responses from the server to the client wherein, when executed, the script adds the nonce to each request from the client to the server; sending the response with the nonce and the script to the client; and verifying that each request from the client includes the nonce sent by the server from the server to the client. The script preferably modifies all objects, including dynamically generated objects, in a server response that may generate future requests to the server to add the nonce to the requests. The server verifies the nonce value in a request and optionally confirms the request with the client if the value is not the same as the value previously sent by the server. Server-side aspects might be embodied in the server or a proxy between the server and the client.

Method and system for preventing cross-site request forgery attack
The invention is applicable for the technical field of network safety, and provides a method and a system for preventing a cross-site request forgery attack. The method comprises the steps that: a client generates an HTTP request when page information of a browser is received; the client performs filtration treatment on cookie information in the HTTP request based on a strategy document obtained from a server-side; the client sends the HTTP request after subjected to the filtration treatment to the server-side. In the method and the system for preventing the cross-site request forgery attack, the strategy document is provided by the server-side, the server-side defines requests from which pages the service-side expects to receive exactly, and the client performs authenticity judgment on the HTTP request based on the strategy document, so that requests which are not allowed by the strategy document are guaranteed to not carry cookie of a user, requests which the server-side does not expect to receive cannot be sent by the client, and the network safety of the client is guaranteed.

Method and device for cross-sit request forgery (CSRF) defense authentication
The invention discloses a method and device for CSRF authentication. The method comprises the following steps: acquiring a secure password needed for this data interaction and sending data interaction requests to the server. The secure password is obtained by a login request sent to the server, which includes the user name and password required for the login. The data interaction request carries authentication information needed for the data interaction and the authentication information is used to indicate that the server authenticates the validity of the data interaction request, wherein the authentication information is determined according to the secure password. By adopting the method provided by the CSRF authentication defense method and device, not only can the protection of the CSRF attack be effectively realized, but also the tamper proof effect is achieved. To a certain extent, the CSRF defense authentication method and device can protect replay attacks and is more versatile.

Guarding against cross-site request forgery (CSRF) attacks
Cross-Site Request Forgery attacks are mitigated by a CSRF mechanism executing at a computing entity. The CSRF mechanism is operative to analyze information associated with an HTTP request for a resource. The HTTP request typically originates as an HTTP redirect from another computing entity, such as an enterprise Web portal. Depending on the nature of the information associated with the HTTP request, the HTTP request may be rejected because the CSRF mechanism determines that the request is or is likely associated with a CSRF attack. To facilitate this determination, the approach leverages a new type of “referer” attribute, a trustedReferer, which indicates that the request originates from a server that has previously established a trust relationship with the site at which the CSRF mechanism executes. The trustedReferer attribute typically is set by the redirecting entity, and in an HTTP request header field dedicated for that attribute.

Cross-site request forgery (CSRF) vulnerability detection
ActiveUS20180351986A1Error detection/correctionDigital data protectionCross-site request forgeryVirtualization
Embodiments detect cross-site request forgery (CSRF) attacks by monitoring, mutation, and analysis of suspect requests that are received by an application server. An engine observes UI interaction, HTTP traffic, and server-side changes in order to create an initial list of CSRF candidates (e.g., HTTP requests that could indicate a CSRF vulnerability). Embodiments may feature a virtualized server-side platform including sensors deployed for application persistence monitoring. Using inter-trace analysis, these CSRF candidates are de-composed into their semantic components (e.g., parameter values and classes). By performing value mutation operations on these components and repeated replay of the resulting HTTP requests, CSRF candidates are tested to see if the underlying HTTP request could be utilized in the context of a CSRF attack. Subsequent validation and exploitability assessment may reduce the initial list of suspect candidate requests to only those exploitable cases for which a proof-of-vulnerability demonstration exploit can be created.

Method and system for authenticating a rich client to a web or cloud application
ActiveUS9699168B2Digital data processing detailsUser identity/authority verificationCross-site request forgeryApplication server
A rich client performs single sign-on (SSO) to access a web- or cloud-based application. According to the described SSO approach, the rich client delegates to its native application server the task of obtaining a credential, such as a SAML assertion. The native server, acting on behalf of the user, obtains an assertion from a federated identity provider (IdP) that is then returned to the rich client. The rich client provides the assertion to a cloud-based proxy, which presents the assertion to an identity manager to attempt to prove that the user is entitled to access the web- or cloud-based application using the rich client. If the assertion can be verified, it is exchanged with a signed token, such as a token designed to protect against cross-site request forgery (CSRF). The rich client then accesses the web- or cloud-based application making a REST call that includes the signed token. The application, which recognizes the request as trustworthy, responds to the call with the requested data.

A secure client-server connection method compatible with RESTful (REpresentational State Transfer) APIs (Application Programming Interface) that is resistant to cross-site scripting (XSS) and cross-site request forgery (CSRF) attacks. The server generates a token for the client and a random value which it pairs with the token. The random value is hashed. The hash value is transmitted to the client contained in the token and the random value is transmitted to the client contained in an HTTPOnly cookie. Even if an attacker steals the token and / or the hash, security is maintained, since the server verifies communications from the client by validating the token on the basis of its hash value. Validation is performed by the server hashing the random value contained in the HTTPOnly cookie paired with the token to obtain a further hash value, and checking that this further hash value matches the token's hash value.
