Apache Struts 2.0.0 through 2.3.4 allows remote attackers to cause a denial of service (CPU consumption) via a long parameter name, which is processed as an OGNL expression.

The token check mechanism in Apache Struts 2.0.0 through 2.3.4 does not properly validate the token name configuration parameter, which allows remote attackers to perform cross-site request forgery (CSRF) attacks by setting the token name configuration parameter to a session attribute.

Apache Struts 2 before 2.2.3.1 evaluates a string as an OGNL expression during the handling of a conversion error, which allows remote attackers to modify run-time data values, and consequently execute arbitrary code, via invalid input to a field.

Multiple cross-site scripting (XSS) vulnerabilities in Apache Struts 1.3.10 allow remote attackers to inject arbitrary web script or HTML via (1) the name parameter to struts-examples/upload/upload-submit.do, or the message parameter to (2) struts-cookbook/processSimple.do or (3) struts-cookbook/processDyna.do.

Multiple cross-site scripting (XSS) vulnerabilities in Apache Struts 2.0.14 and 2.2.3 allow remote attackers to inject arbitrary web script or HTML via the (1) name or (2) lastName parameter to struts2-showcase/person/editPerson.action, or the (3) clientName parameter to struts2-rest-showcase/orders.

Apache Struts 2.3.1.2 and earlier, 2.3.19-2.3.23, provides interfaces that do not properly restrict access to collections such as the session and request collections, which might allow remote attackers to modify run-time data values via a crafted parameter to an application that implements an affected interface, as demonstrated by the SessionAware, RequestAware, ApplicationAware, ServletRequestAware, ServletResponseAware, and ParameterAware interfaces. NOTE: the vendor disputes the significance of this report because of an "easy work-around in existing apps by configuring the interceptor."

The DebuggingInterceptor component in Apache Struts before 2.3.1.1, when developer mode is used, allows remote attackers to execute arbitrary commands via unspecified vectors. NOTE: the vendor characterizes this behavior as not "a security vulnerability itself.

The ParameterInterceptor component in Apache Struts before 2.3.1.1 does not prevent access to public constructors, which allows remote attackers to create or overwrite arbitrary files via a crafted parameter that triggers the creation of a Java object.

The CookieInterceptor component in Apache Struts before 2.3.1.1 does not use the parameter-name whitelist, which allows remote attackers to execute arbitrary commands via a crafted HTTP Cookie header that triggers Java code execution through a static method.

The ExceptionDelegator component in Apache Struts before 2.2.3.1 interprets parameter values as OGNL expressions during certain exception handling for mismatched data types of properties, which allows remote attackers to execute arbitrary Java code via a crafted parameter.

XWork 2.2.1 in Apache Struts 2.2.1, and OpenSymphony XWork in OpenSymphony WebWork, allows remote attackers to obtain potentially sensitive information about internal Java class paths via vectors involving an s:submit element and a nonexistent method, a different vulnerability than CVE-2011-1772.3.

Multiple cross-site scripting (XSS) vulnerabilities in component handlers in the javatemplates (aka Java Templates) plugin in Apache Struts 2.x before 2.2.3 allow remote attackers to inject arbitrary web script or HTML via an arbitrary parameter value to a .action URI, related to improper handling of value attributes in (1) FileHandler.java, (2) HiddenHandler.java, (3) PasswordHandler.java, (4) RadioHandler.java, (5) ResetHandler.java, (6) SelectHandler.java, (7) SubmitHandler.java, and (8) TextFieldHandler.java.

Multiple cross-site scripting (XSS) vulnerabilities in XWork in Apache Struts 2.x before 2.2.3, and OpenSymphony XWork in OpenSymphony WebWork, allow remote attackers to inject arbitrary web script or HTML via vectors involving (1) an action name, (2) the action attribute of an s:submit element, or (3) the method attribute of an s:submit element.

Apache Tiles 2.1 before 2.1.2, as used in Apache Struts and other products, evaluates Expression Language (EL) expressions twice in certain circumstances, which allows remote attackers to conduct cross-site scripting (XSS) attacks or obtain sensitive information via unspecified vectors, related to the (1) tiles:putAttribute and (2) tiles:insertTemplate JSP tags.

Multiple cross-site scripting (XSS) vulnerabilities in Apache Struts 2.0.x before 2.0.11.1 and 2.1.x before 2.1.1 allow remote attackers to inject arbitrary web script or HTML via vectors associated with improper handling of (1) " (double quote) characters in the href attribute of an s:a tag and (2) parameters in the action attribute of an s:url tag.

Cross-site scripting (XSS) vulnerability in Apache Struts before 1.2.9-162.31.1 on SUSE Linux Enterprise (SLE) 11, before 1.2.9-108.2 on SUSE openSUSE 10.3, before 1.2.9-198.2 on SUSE openSUSE 11.0, and before 1.2.9-162.163.2 on SUSE openSUSE 11.1 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors related to "insufficient quoting of parameters."

Multiple cross-site scripting (XSS) vulnerabilities in Dojo 0.4.1 and 0.4.2, as used in Apache Struts and other products, allow remote attackers to inject arbitrary web script or HTML via unspecified vectors involving (1) xip_client.html and (2) xip_server.html in src/io/.

Multiple directory traversal vulnerabilities in Apache Struts 2.0.x before 2.0.12 and 2.1.x before 2.1.3 allow remote attackers to read arbitrary files via a ..%252f (encoded dot dot slash) in a URI with a /struts/ path, related to (1) FilterDispatcher in 2.0.x and (2) DefaultStaticContentLoader in 2.1.x.

ParametersInterceptor in OpenSymphony XWork 2.0.x before 2.0.6 and 2.1.x before 2.1.2, as used in Apache Struts and other products, does not properly restrict # (pound sign) references to context objects, which allows remote attackers to execute Object-Graph Navigation Language (OGNL) statements and modify server-side context objects, as demonstrated by use of a \u0023 representation for the # character.

Struts support in OpenSymphony XWork before 1.2.3, and 2.x before 2.0.4, as used in WebWork and Apache Struts, recursively evaluates all input as an Object-Graph Navigation Language (OGNL) expression when altSyntax is enabled, which allows remote attackers to cause a denial of service (infinite loop) or execute arbitrary code via form input beginning with a "%{" sequence and ending with a "}" character.
