如何獲取360站長邀請碼,360網站安全站長邀請碼html
首先360可以提供一個這樣平臺去檢測仍是不錯的。可是當體檢出來 看到漏洞報告,覺得360會像windows上360安全衛士同樣幫咱們打好補丁。可是實際發現漏洞是要本身修復,而且php和asp aspx有360提供的補丁或者解決方案(想要看這些方案以前要申請爲站長可是須要邀請碼 這個能夠在頁面 頁面左下角 360主機衛士感恩卡里面領取)。java
進入修復方案後發現java幾乎沒有提供一些建議,只能本身處理。開始使用搜索引擎搜索 java防止xss攻擊代碼。linux
http://www.yihaomen.com/article/java/409.htmweb
查到了這個方案spring
. 能夠採用spring 裏面提供的工具類來實現.
一, 第一種方法。shell
public class XSSFilter implements Filter { @Override public void init(FilterConfig filterConfig) throws ServletException { } @Override public void destroy() { } @Override public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { chain.doFilter(new XSSRequestWrapper((HttpServletRequest) request), response); } }
再實現 ServletRequest 的包裝類windows
import java.util.regex.Pattern; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletRequestWrapper; public class XSSRequestWrapper extends HttpServletRequestWrapper { public XSSRequestWrapper(HttpServletRequest servletRequest) { super(servletRequest); } @Override public String[] getParameterValues(String parameter) { String[] values = super.getParameterValues(parameter); if (values == null) { return null; } int count = values.length; String[] encodedValues = new String[count]; for (int i = 0; i < count; i++) { encodedValues[i] = stripXSS(values[i]); } return encodedValues; } @Override public String getParameter(String parameter) { String value = super.getParameter(parameter); return stripXSS(value); } @Override public String getHeader(String name) { String value = super.getHeader(name); return stripXSS(value); } private String stripXSS(String value) { if (value != null) { // NOTE: It's highly recommended to use the ESAPI library and uncomment the following line to // avoid encoded attacks. // value = ESAPI.encoder().canonicalize(value); // Avoid null characters value = value.replaceAll("", ""); // Avoid anything between script tags Pattern scriptPattern = Pattern.compile("<script>(.*?)</script>", Pattern.CASE_INSENSITIVE); value = scriptPattern.matcher(value).replaceAll(""); // Avoid anything in a src='...' type of expression scriptPattern = Pattern.compile("src[\r\n]*=[\r\n]*\\\'(.*?)\\\'", Pattern.CASE_INSENSITIVE | Pattern.MULTILINE | Pattern.DOTALL); value = scriptPattern.matcher(value).replaceAll(""); scriptPattern = Pattern.compile("src[\r\n]*=[\r\n]*\\\"(.*?)\\\"", Pattern.CASE_INSENSITIVE | Pattern.MULTILINE | Pattern.DOTALL); value = scriptPattern.matcher(value).replaceAll(""); // Remove any lonesome </script> tag scriptPattern = Pattern.compile("</script>", Pattern.CASE_INSENSITIVE); value = scriptPattern.matcher(value).replaceAll(""); // Remove any lonesome <script ...> tag scriptPattern = Pattern.compile("<script(.*?)>", Pattern.CASE_INSENSITIVE | Pattern.MULTILINE | Pattern.DOTALL); value = scriptPattern.matcher(value).replaceAll(""); // Avoid eval(...) expressions scriptPattern = Pattern.compile("eval\\((.*?)\\)", Pattern.CASE_INSENSITIVE | Pattern.MULTILINE | Pattern.DOTALL); value = scriptPattern.matcher(value).replaceAll(""); // Avoid expression(...) expressions scriptPattern = Pattern.compile("expression\\((.*?)\\)", Pattern.CASE_INSENSITIVE | Pattern.MULTILINE | Pattern.DOTALL); value = scriptPattern.matcher(value).replaceAll(""); // Avoid javascript:... expressions scriptPattern = Pattern.compile("javascript:", Pattern.CASE_INSENSITIVE); value = scriptPattern.matcher(value).replaceAll(""); // Avoid vbscript:... expressions scriptPattern = Pattern.compile("vbscript:", Pattern.CASE_INSENSITIVE); value = scriptPattern.matcher(value).replaceAll(""); // Avoid onload= expressions scriptPattern = Pattern.compile("onload(.*?)=", Pattern.CASE_INSENSITIVE | Pattern.MULTILINE | Pattern.DOTALL); value = scriptPattern.matcher(value).replaceAll(""); } return value; } }
還須要到web.xml裏面配置安全
<filter> <filter-name>XSSFilter</filter-name> <filter-class>com.shanheyongmu.XSSFilter</filter-class> </filter> <filter-mapping> <filter-name>XSSFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
放上去以後 出現了 Java.lang.UnsupportedClassVersionError仍是classnotfound 項目跑起來就是首頁404。 而後考慮了下linux環境是jdk 1.6而編譯的都是maven3.3.0之後版本以及使用的jdk 1.7 版本問題(版本切換步驟能夠參考【maven學習總結】裏面的execption ,版本以前工做中遇到過因此有印象) 從新換jdk和eclipse設置jdk都是1.6以後編譯。不報錯了shell上,可是用360快速檢測我已修復,仍是存在漏洞。因而繼續百度
http://www.what21.com/programming/java/javaweb-summary/xss3.html 發現了不一樣的XssFilter寫法,嘗試以後仍是失敗。
https://my.oschina.net/wanglu/blog/267069 Springmvc安全 ,嘗試以後失敗,固然有些人視圖解析器不一樣 無加spring 的form標籤 沒法嘗試。
http://www.cnblogs.com/Mainz/archive/2012/11/01/2749874.html 來到了本篇 本篇有3種解決方法
第二種方法
web.xml加上:
<context-param> <param-name>defaultHtmlEscape</param-name> <param-value>true</param-value> </context-param>
Forms加上:不少人對forms究竟是哪裏不理解你能夠 加在<form>標籤以前 或者body以前
<form:input path="someFormField" htmlEscape="true" />
可是<spring:htmlEscape defaultHtmlEscape="true" />在jsp視圖解析中仍是能夠的,而且這個添加方法 能夠不改變原有項目。
所有部署完成後,遺憾的是仍是體檢有原有漏洞。
從這篇獲得了答案 而且修復了 http://huangpengpeng.iteye.com/blog/2091798

因爲嘗試較多,也比較混亂,也不肯定哪一個適用各位的狀況,只能多查多參考。

遺憾的是配置文件很難找 我在csdn找到了antisamy.xml,你們能夠基於搜索關鍵字 Antisamy項目實現防XSS攻擊多查查 。
