Apache Struts Jakarta Multipart parser allows for malicious file upload using the Content-Type value, leading to remote code execution.
Forced OGNL evaluation, when evaluated on raw user input in tag attributes, may lead to remote code execution. Affected software : Apache Struts 2.0.0 - Struts 2.5.25.
Improper neutralization of special elements used in an expression language statement ('Expression Language Injection') vulnerability in Apache Struts. If the application is configured to use the legacy RESTful action mapper, a crafted request can inject an OGNL expression that may lead to remote code execution. Struts 7 is affected only when the OGNL allowlist is disabled; it is enabled by default. Applications using the default action mapper, the restful2 mapper, or the Struts REST plugin are not affected.
This issue affects Apache Struts: from 2.0.0 through 2.3.37, from 2.5.0 through 2.5.33, from 6.0.0 through 6.11.0, from 7.0.0 through 7.3.0.
Users are recommended to upgrade to version 6.12.0 or 7.4.0, which fixes the issue.
Apache Struts 2.0.0 through 2.3.15 allows remote attackers to execute arbitrary OGNL expressions via a parameter with a crafted (1) action:, (2) redirect:, or (3) redirectAction: prefix.
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.
The Struts 1 plugin in Apache Struts 2.1.x and 2.3.x might allow remote code execution via a malicious field value passed in a raw message to the ActionMessage.
An attacker can manipulate file upload params to enable paths traversal and under some circumstances this can lead to uploading a malicious file which can be used to perform Remote Code Execution. Users are recommended to upgrade to versions Struts 2.5.33 or Struts 6.3.0.2 or greater to fix this issue.
Microsoft Power Platform Connector Spoofing Vulnerability
File upload logic in Apache Struts is flawed. An attacker can manipulate file upload params to enable paths traversal and under some circumstances this can lead to uploading a malicious file which can be used to perform Remote Code Execution.
This issue affects Apache Struts: from 2.0.0 before 6.4.0.
Users are recommended to upgrade to version 6.4.0 at least and migrate to the new file upload mechanism https://struts.apache.org/core-developers/file-upload . If you are not using an old file upload logic based on FileuploadInterceptor your application is safe.

A vulnerability introduced by forcing parameter inclusion in the URL and Anchor Tag allows remote command execution, session access and manipulation and XSS attacks.
both the s:url and s:a tag provide an includeParams attribute.
The main scope of that attribute is to understand whether includes http request parameter or not.
The allowed values of includeParams are:
none - include no parameters in the URL (default) get - include only GET parameters in the URL all - include both GET and POST parameters in the URL
A request that included a specially crafted request parameter could be used to inject arbitrary OGNL code into the stack, afterward used as request parameter of an URL or A tag , which will cause a further evaluation.
The second evaluation happens when the URL/A tag tries to resolve every parameters present in the original request. This lets malicious users put arbitrary OGNL statements into any request parameter (not necessarily managed by the code) and have it evaluated as an OGNL expression to enable method execution and execute arbitrary methods, bypassing Struts and OGNL library protections.
The issue was originally addressed by Struts 2.3.14.1 and Security Announcement S2-013. However, the solution introduced with 2.3.14.1 did not address all possible attack vectors, such that every version of Struts 2 before 2.3.14.2 is still vulnerable to such attacks.
An unspecified SQL Injection vulnerability in Ivanti Endpoint Manager released prior to 2022 SU 5 allows an attacker with access to the internal network to execute arbitrary SQL queries and retrieve output without the need for authentication. Under specific circumstances, this may also lead to RCE on the core server.
Concurrent execution using shared resource with improper synchronization ('race condition') vulnerability in Apache Struts. Where a localized message formats a date or time argument, the formatter retained for that message by the application-wide text provider is used by concurrently served requests without isolation, so a value belonging to one user can appear in another user's response, or the rendering can fail and surface as a server error. Applications whose localized messages format no date or time arguments are not affected.
This issue affects Apache Struts: from 2.0.0 through 2.3.37, from 2.5.0 through 2.5.33, from 6.0.0 through 6.11.0, from 7.0.0 through 7.3.0.
Users are recommended to upgrade to version 6.12.0 or 7.4.0, which fixes the issue.
A local code execution issue exists in Apache Struts2 when processing malformed XSLT files, which could let a malicious user upload and execute arbitrary files.
Internet Connection Sharing (ICS) Remote Code Execution Vulnerability
Internet Connection Sharing (ICS) Remote Code Execution Vulnerability
Denial of Service vulnerability in Apache Struts, file leak in multipart request processing causes disk exhaustion.
This issue affects Apache Struts: from 2.0.0 through 6.7.4, from 7.0.0 through 7.0.3.
Users are recommended to upgrade to version 6.8.0 or 7.1.1, which fixes the issue.
ActionServlet.java in Apache Struts 1 1.x through 1.3.10 does not properly restrict the Validator configuration, which allows remote attackers to conduct cross-site scripting (XSS) attacks or cause a denial of service via crafted input, a related issue to CVE-2015-0899.
Apache Struts REST Plugin uses an XStreamHandler with an instance of XStream for deserialization without any type filtering, which can lead to remote code execution when deserializing XML payloads.
Missing XML Validation vulnerability in Apache Struts, Apache Struts.
This issue affects Apache Struts: from 2.0.0 before 2.2.1; Apache Struts: from 2.2.1 through 6.1.0.
Users are recommended to upgrade to version 6.1.1, which fixes the issue.
A vulnerability in Apache Struts 1 ActionForm allowing unintended remote operations against components on server memory, such as Servlets and ClassLoader, was found.

Apache Struts 2.3.19 to 2.3.20.2, 2.3.21 to 2.3.24.1, and 2.3.25 to 2.3.28, when Dynamic Method Invocation is enabled, allow remote attackers to execute arbitrary code via method: prefix, related to chained expressions.
Apache Struts contains a Remote Code Execution when using results with no namespace and it's upper actions have no or wildcard namespace. The same flaw exists when using a url tag with no value, action set, and it's upper actions have no or wildcard namespace.
Windows MSHTML Platform Remote Code Execution Vulnerability
Impact The vulnerability may allow a remote attacker to request data from internal resources that are not publicly available only by manipulating the processed input stream.
Patches If you rely on XStream's default blacklist of the Security Framework, you will have to use at least version 1.4.15.
Workarounds The reported vulnerability does not exist running Java 15 or higher.
No user is affected, who followed the recommendation to setup XStream's Security Framework with a whitelist! Anyone relying on XStream's default blacklist can immediately switch to a whilelist for the allowed types to avoid the vulnerability.
Users of XStream 1.4.14 or below who still insist to use XStream default blacklist - despite that clear recommendation - can use a workaround depending on their version in use.
Users of XStream 1.4.14 can simply add two lines to XStream's setup code: Java xstream.denyTypes(new String[]{ "jdk.nashorn.internal.objects.NativeString" }); xstream.denyTypesByRegExp(new String[]{ ".\\.ReadAllStream\\$FileStream" });
Users of XStream 1.4.14 to 1.4.13 can simply add three lines to XStream's setup code: Java xstream.denyTypes(new String[]{ "javax.imageio.ImageIO$ContainsFilter", "jdk.nashorn.internal.objects.NativeString" }); xstream.denyTypes(new Class[]{ java.lang.ProcessBuilder.class }); xstream.denyTypesByRegExp(new String[]{ ".\\.ReadAllStream\\$FileStream" }); Users of XStream 1.4.12 to 1.4.7 who want to use XStream with a black list will have to setup such a list from scratch and deny at least the following types: javax.imageio.ImageIO$ContainsFilter, java.beans.EventHandler, java.lang.ProcessBuilder, jdk.nashorn.internal.objects.NativeString.class, java.lang.Void and void and deny several types by name pattern. Java xstream.denyTypes(new String[]{ "javax.imageio.ImageIO$ContainsFilter", "jdk.nashorn.internal.objects.NativeString" }); xstream.denyTypes(new Class[]{ java.lang.ProcessBuilder.class, "jdk.nashorn.internal.objects.NativeString", java.beans.EventHandler.class, java.lang.ProcessBuilder.class, java.lang.Void.class, void.class }); xstream.denyTypesByRegExp(new String[]{ ".\\$LazyIterator", "javax\\.crypto\\..", ".\\.ReadAllStream\\$FileStream" }); Users of XStream 1.4.6 or below can register an own converter to prevent the unmarshalling of the currently know critical types of the Java runtime. It is in fact an updated version of the workaround for CVE-2013-7285: Java xstream.registerConverter(new Converter() { public boolean canConvert(Class type) { return type != null && (type == java.beans.EventHandler.class || type == java.lang.ProcessBuilder.class || type.getName().equals("javax.imageio.ImageIO$ContainsFilter") || type.getName().equals("jdk.nashorn.internal.objects.NativeString") || type == java.lang.Void.class || void.class || Proxy.isProxy(type)) || type.getName().startsWith("javax.crypto.") || type.getName().endsWith("$LazyIterator") || type.getName().endsWith(".ReadAllStream$FileStream")); }
public Object unmarshal(HierarchicalStreamReader reader, UnmarshallingContext context) { throw new ConversionException("Unsupported type due to security reasons."); }
public void marshal(Object source, HierarchicalStreamWriter writer, MarshallingContext context) { throw new ConversionException("Unsupported type due to security reasons."); } }, XStream.PRIORITYLOW); For more information If you have any questions or comments about this advisory: Open an issue in XStream Contact us at XStream Google Group
Denial of Service vulnerability in Apache Struts, file leak in multipart request processing causes disk exhaustion.
This issue affects Apache Struts: from 2.0.0 through 6.7.0, from 7.0.0 through 7.0.3.
Users are recommended to upgrade to version 6.8.0 or 7.1.1, which fixes the issue.
Apache Commons BeanUtils, as distributed in lib/commons-beanutils-1.8.0.jar in Apache Struts 1.x through 1.3.10 and in other products requiring commons-beanutils through 1.9.2, does not suppress the class property, which allows remote attackers to "manipulate" the ClassLoader and execute arbitrary code via the class parameter, as demonstrated by the passing of this parameter to the getClass method of the ActionForm object in Struts 1.
Uncontrolled resource consumption vulnerability in the JSON plugin of Apache Struts. When an application is configured to populate actions from a JSON request body, the plugin reads that body into memory without bounding how much it will accept, so a single request can exhaust the heap and deny service to other users. The plugin's configurable JSON input length limit does not bound this read. The JSON plugin is an optional component; applications that do not use it, or use it without enabling JSON request-body handling, are not affected.
This issue affects Apache Struts: from 2.1.8 through 2.3.37, from 2.5.0 through 2.5.33, from 6.0.0 through 6.10.0, from 7.0.0 through 7.2.1.
Users are recommended to upgrade to version 6.11.0 or 7.3.0, which fixes the issue.
Allocation of resources without limits or throttling vulnerability in Apache Struts. When no fixed locale is configured, the locale used for localized-text lookups is taken from the incoming request, allowing an unauthenticated remote client to cause the framework's internal localized-text caches to grow without bound and exhaust the Java heap, denying service to other users. Applications that configure a fixed locale are not affected.
This issue affects Apache Struts: from 2.0.0 through 2.3.37, from 2.5.0 through 2.5.33, from 6.0.0 through 6.10.0, from 7.0.0 through 7.2.1.
Users are recommended to upgrade to version 6.11.0 or 7.3.0, which fixes the issue.
Uncontrolled resource consumption vulnerability in Apache Struts. An application that exposes an endpoint collecting Content Security Policy violation reports reads the submitted report into memory without bounding how much it will accept, so a single request can exhaust the heap and deny service to other users. Such endpoints are ordinarily reachable without authentication. The core distribution maps no such endpoint by default; applications that do not collect violation reports are not affected.
This issue affects Apache Struts: from 6.0.0 through 6.10.0, from 7.0.0 through 7.2.1.
Users are recommended to upgrade to version 6.11.0 or 7.3.0, which fixes the issue.
It was found that the fix for CVE-2014-0094 was incomplete. The Struts 2 ParametersInterceptor was updated to block access to the 'class' parameter, but not all forms in which this parameter can be specified were blocked. A remote attacker could use this flaw to manipulate the ClassLoader used by the application server running Struts 2. This could lead to arbitrary remote code execution under certain conditions.
This flaw is reported to affect Struts 2.0.0 through to Struts 2.3.16.1. It is corrected in 2.3.16.2.
