AJAX TESTING

1. AJAX Vulnerabilities
Asynchronous Javascript and XML (AJAX) is one of the latest techniques used by web application developers to provide a user experience similar to that of a local application. Since AJAX is still a new technology, there are many security issues that have not yet been fully researched. Some of the security issues in AJAX include:
• Increased attack surface with many more inputs to secure
• Exposed internal functions of the application
• Client access to third-party resources with no built-in security and encoding mechanisms
• Failure to protect authentication information and sessions
• Blurred line between client-side and server-side code, resulting in security mistakes
2. How to test AJAx
Because most attacks against AJAX applications are analogs of attacks against traditional web applications, testers should refer to other sections of the testing guide to look for specific parameter manipulations to use in order to discover vulnerabilities. The challenge with AJAX-enabled applications is often finding the endpoints that are the targets for the asynchronous calls and then determining the proper format for requests.

Authorization Testing

Image
1. Testing for Path Traversal First, we test if it is possible to find a way to execute a path traversal attack and access reserved information About input vector: 2. Testing for bypassing authorization schema This kind of test focuses on verifying how the authorization schema has been implemented for each role/privilege to get access to reserved functions/resources. 3. Testing for Privilege Escalation During this phase, the tester should verify that it is not possible for a user to modify his or her privileges/roles inside the application in ways that could allow privilege escalation attacks.

Bypass HTML Field Restrictions

This time I learn about Bypass HTML Field Restrictions. I bypass the html form . In order to pass this lesson , I must submit the form with each field containing the value of unallowed . I have to submit an invalid value for all six fields in one delivery form provided . that is : select field which has two choices , radio button which has two choices , input field which retricted to 5 character, and disableinput field with a form that can not be filled . And this some way that I have tried to bypass it : First I submibt that form as usual and I did not find any change Then I tried to intercept request by webscarab, I change values that not provided there. but I not find any changes too. I studied again after it there are only 5 fields in the request when the procedure mentioned there are 6 fields . then I add a new field that is itself disableinput field , the parameter I get from the source web page . but I not find
