When everyone is emphasizing how good HTML5 is, and all are focusing on HTML5/css3, HTML5 is also exposed to several possible security issues, this is a series of complications behind HTML5's excellent standards, but it does not affect the impact of HTML5 standards on the future. We only need to know and prevent them. The following content does not use any special sequence. We will introduce five methods th

At the same time, because the encrypted data returned by the MCrypt function is a binary data, saving to

Even a web developer at the 11th stream level knows that "do not modify data based on the content of the GET request" does not comply. If the data of all update operations is checked to see if it is a POST request, will there be a mental attack like using URL? Attackers did not even use csrf/XSS to be slightly more intelligent. A few months ago, although the content displayed on the home page was tested XSS too much, but the XSS (Android mobile client) can be successfully displayed on the d

A security issue of struts 1.x is worth noting. Because the previous mode was passed in by the front-end page data through actionform, The excute method in the action was received, and this problem does not exist. However, if you define instance variables directly in action, the problem is very high. The reason is actually very simple:To ensure thread-safe, the Struts framework creates only one action instance for each action class in the life cycl

malicious use of the site. Although it sounds like a cross-site script (XSS), it is very different from XSS and is almost at odds with the way it is attacked. XSS leverages trusted users within the site, while CSRF leverages trusted sites by disguising requests from trusted users. Compared to XSS attacks, csrf attacks are often less prevalent (and therefore have very few resources to protect against them) and are difficult to guard against, so they are considered more dangerous than XSS.For exa
