CVE-2013-2115: Struts2 core Code Injection Vulnerability
HIGHCVE-2013-2115 is a HIGH (CVSS 8.1) code injection vulnerability (CWE-94: Improper Control of Generation of Code ('Code Injection')) affecting Struts2 core libraries in the Maven ecosystem. The issue involves code injection in apache struts. Remediation is available by upgrading affected packages to version 2.3.14.2.
CVE-2013-2115 at a Glance
Security Impact
CVSS: 8.1
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H).
How to Fix CVE-2013-2115
To remediate this vulnerability, upgrade all affected Struts2 core dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
<dependency>
<groupId>org.apache.struts</groupId>
<artifactId>struts2-core</artifactId>
<version>2.3.14.2</version>
</dependency>
<dependency>
<groupId>org.apache.struts.xwork</groupId>
<artifactId>xwork-core</artifactId>
<version>2.3.14.2</version>
</dependency>
Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:tree -Dincludes=org.apache.struts
How to Check if You Are Affected
To determine whether your Java application is affected by CVE-2013-2115, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=org.apache.struts
Analyze the terminal output to locate any version of Struts2 core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.3.14.2), your application is affected.
Note: The mvn dependency:tree -Dincludes=org.apache.struts command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In Struts2 core, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

"details" : "A vulnerability introduced by forcing parameter inclusion in the URL and Anchor Tag allows remote command execution, session access and manipulation and XSS attacks.\n\nboth the s:url and s:a tag provide an includeParams attribute.\n\nThe main scope of that attribute is to understand whether includes http request parameter or not.\n\nThe allowed values of includeParams are:\n\n none - include no parameters in the URL (default)\n get - include only GET parameters in the URL\n all - include both GET and POST parameters in the URL\n\nA 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.\n\nThe second evaluation happens when the URL/A tag tries to resolve every parameters present in the original request.\nThis 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.\n\nThe issue was originally addressed by Struts 2.3.14.1 and Security Announcement [S2-013](https://cwiki.apache.org/confluence/display/WW/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.",
