WebScarab is a proxy tool. It can intercept the communication process of the web browser and analyze the content so that you can easily modify it. For example, if I send a submit request, webScarab first intercepts the content and does not rush to the Real Server. Instead, a window pops up to allow you to modify the content. After the modification is completed, it is submitted to the server. If some restrictions are imposed on the webpage input box, for example, the length limit and Number For

Sometimes a character is like a ghost, and we cannot feel it. For example, the earlier version of Firefox ignores 0x80, while the earlier version of IE ignores 0x00. This is undoubtedly a headache, because for the filter, the script is not equals[0x00]cript. For example, some characters in the position will be ignored in chrome (which can be used now ):
Sometimes it will not only exist silently
Previously, I introduced Brute Force, which is the most common type of web attacks. Today I will introduce command injection attacks.
The so-called web command attack means that the data entered by all users in the system is used without strict filtering, thus leaving hackers with a chance.
I am not very familiar with web command attacks. Let me introduce two links to web command attacks.

We have made statistics on common vulnerabilities, and found that the proportion of unauthorized operations is the highest. Basically, we have found these vulnerabilities on the platforms we have tested, this includes arbitrary user information query and deletion. The most serious vulnerability occurs in account security, including resetting any user password and brute-force cracking of verification
On SendSafely.com we make heavy use of latest new JavaScript APIs introduced with HTML5. We encrypt files, calculate checksums and upload data using pure JavaScript. moving logic like this down to the browser, however, makes the threat of Cross-Site Scripting (XSS) even greater than before. in order to prevent XSS vulnerabilities, our site makes liberal use of pretty aggressive client-side and server-side encoding APIs. these APIs are based on the owasp
