Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Multiple open redirect vulnerabilities in Apache Struts 2.0.0 through 2.3.15 allow remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via a URL in a parameter using the (1) redirect: or (2) redirectAction: prefix.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Apache Struts 2 versions 2.0.0 through 2.3.15 contain open redirect vulnerabilities in the redirect: and redirectAction: prefix parameters. Attackers can craft malicious URLs that redirect users to arbitrary external websites, enabling phishing campaigns. The vulnerability stems from insufficient validation of user-supplied redirect targets.

MitigationUpgrade Apache Struts 2 to version 2.3.15.1 or later, which contains the patched version. If immediate patching is not feasible, implement URL validation at the application proxy or web application firewall layer to block suspicious redirect patterns.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify Apache Struts 2 library version
    Locate the struts2-core.jar file in your application WEB-INF/lib directory. Check the MANIFEST.MF file inside the JAR for the Implementation-Version attribute, or use your build system/pom.xml to confirm the Struts version dependency.
    Affected if The installed version is between 2.0.0 and 2.3.15 inclusive.
  2. Verify use of redirect result types
    Search your struts.xml, struts-default.xml, and action Java classes for occurrences of 'redirect:' or 'redirectAction:' result type declarations.
    Affected if The application uses redirect: or redirectAction: result types in any action configuration.
  3. Inspect redirect parameter handling in application code
    Review action classes and interceptors that process the 'redirect:' or 'redirectAction:' parameters. Check if user-supplied input (query parameters, form inputs) is used to build the redirect target without validation.
    Affected if User-controlled input can influence the redirect target without server-side validation allowing arbitrary external URLs.
  4. Check web server or WAF logs for suspicious redirect patterns
    Review access logs for URLs containing redirect: or redirectAction: parameters with external domains (http://, https://) or patterns like 'redirect:http'.
    Affected if Requests with external URLs in redirect parameters are being processed by the application.

You are affected if your Apache Struts 2 version is between 2.0.0 and 2.3.15 and your application uses redirect: or redirectAction: result types with user-influenced redirect targets.

Mitigation

Upgrade Apache Struts 2 to version 2.3.15.1 or later, which contains the patched version. If immediate patching is not feasible, implement URL validation at the application proxy or web application firewall layer to block suspicious redirect patterns.
