toolkits:ZAP (Zed Attack Proxy project) is a penetration testing tool that looks for vulnerabilities in WEB applications. One of ZAP's design goals is to make it easy to use, making it easy for developers and testers who are not experts in the security field to use it. ZAP provides automatic scanning and a set of manual test Toolsets.The Xenotix XSS Exploit Framework is an advanced cross-site scripting vulnerability detection and exploit framework th

1. Dependency-check can check for known, publicly disclosed vulnerabilities in project dependency packages. Currently good support for Java and. NET; Ruby, node. js, andPython are in the experimental phase, and C + + is supported only through (autoconf and CMake). The owasp2017 Top10 is mainly available for a9-using components with known vulnerabilities. Solution to the problem2, Dependency-check has command line interface, MAVEN plugin, Jenkins plug-ins and so on. The core function is to detect

Injection Injection flaws, such as SQL, OS, and LDAP injection, occur when untrusted data are sent to an interpreter as part of a COM Mand or query. The attacker ' s hostile data can trick the interpreter into executing unintended commands or accessing unauthorized data. Cross Site Scripting (XSS) XSS flaws occur whenever an application takes untrusted data

SummaryHTML injection is a type of injection issue this occurs when a user are able to control an input point and are able to injec T arbitrary (any) HTML code into a vulnerable web page. This vulnerability can has many consequences (consequences), like disclosure of a user's session cookies that could is used to Imper Sonate (imitation) The victim, or, more generally, it can allow the attacker to modify the page content seen by the victims.This vulnerability occurs when the user input was not c

trusted website page, and the user's account theft often leads to significant losses, so it is also a huge hazard.3. Cross-site request forgeryCross-site Request forgery (Cross-siterequest forgery,csrf), as the owasp organization of the 2007 proposed ten security breaches of the five, it is also a derivative of XSS attacks. The so-called cross-site request forgery is the way an attacker injects a script us

In some cases, we cannot use any ready-made XSS Code and are all filtered out. Therefore, we need to make some judgments and guesses on the filtering rules. Then use some targeted skills to adapt to or bypass the rules. In this example, we use the log function of QQ space/QQ alumni as an example to guess simple filtering rules, and then use the flash containing addCallback to construct a storage-type XSS. D

The Crosssite Scripting (cross-site scripting attack) in the OWASP Top 10 security threat allows an attacker to inject malicious script into the Web site through a browser.
