Web Security (1): cross-site scripting (XSS) and security-related xss
IntroductionCross-Site Scripting (XSS) attacks are not abbreviated to Cascading Style Sheet (CSS). Therefore, XSS attacks are abbreviated to Cross-Site Scripting (XSS) attacks. A malicious attacker inserts
What is feature vector, feature value, matrix decomposition?
[1. mathematical significance of features]First, we examine a linear change. For example, the elliptic equation in the X and Y coordinate systems can be written as x ^ 2/A ^ 2 + y ^ 2/B ^ 2 = 1, after the coordinate system rotates the origin, the elliptic equation will undergo transformation. We can multiply the (x, y) of the original coordinate system by a matrix to obtain a new (x', y') representation, written as an operator in the f
When an XSS occurs in a blind input box, when an XSS session expires, or when the session expires, the cookie statement is incorrect. Go to the background and reset any user password. How many images of the website will all be suspended? How many websites will be implicated? I started school again and had a lot of thoughts. There are still more than 1000 days before the college entrance examination. I miss

Html is a very interesting language ..
The xss code in the bbs posting area of cmseasy performs a complete filtering of the html code in
function xss_clean($data) { if (empty($data)) { return $data; } if (is_array($data)) { foreach ($data as $key => $value)
Php xss filtering and xss Filtering
XSS, also known as CSS (Cross Site Script), is a Cross-Site scripting attack. A malicious attacker inserts malicious html code into a Web page. When a user browses this page, the html code embedded in the Web page is executed, in this way, some people are attacked.

how to attack targets and use loads. You have multiple options:* System Calibration *:These options are useful for XSS attacks with filters and or repeat the code used:--hash if the target repeats content, the hash is detected every time(Useful for predicting results that may be wrong)--heuristic heuristic settings detect that those scripts will be filtered:;\/* Select Attack vector (s) *:These options are used in special
