CVE-2006-1547
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 · uneditedActionForm in Apache Software Foundation (ASF) Struts before 1.2.9 with BeanUtils 1.7 allows remote attackers to cause a denial of service via a multipart/form-data encoded form with a parameter name that references the public getMultipartRequestHandler method, which provides further access to elements in the CommonsMultipartRequestHandler implementation and BeanUtils.
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 confidenceCVE-2006-1547 is a vulnerability in Apache Struts before version 1.2.9 that allows remote attackers to cause a denial of service by exploiting a multipart/form-data encoded form. The vulnerability arises from a parameter name that references the public getMultipartRequestHandler method, leading to further access to elements in the CommonsMultipartRequestHandler implementation and BeanUtils.

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 checksWork through these to decide whether this CVE applies to you.
-
Check installed version of Apache StrutsRun the command to check the version of Apache Struts installed in your environmentAffected if The installed version is less than 1.2.9
-
Inspect multipart/form-data handlingReview the configuration files or code to see if multipart/form-data handling is enabledAffected if Multipart/form-data handling is enabled
-
Verify usage of getMultipartRequestHandlerSearch the codebase for references to the getMultipartRequestHandler methodAffected if The method getMultipartRequestHandler is referenced in the application code
You are affected if you are using Apache Struts version less than 1.2.9 with multipart/form-data handling enabled.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped1.2.9
To remediate this vulnerability, upgrade to Apache Struts version 1.2.9 or later. Additionally, review and sanitize input parameters in multipart/form-data requests to prevent exploitation.
Struts 1.2.9 or later
- 1. Identify the current Apache Struts version in use by checking project dependencies or library files.
- 2. Download Apache Struts version 1.2.9 or later from the official Apache Struts repository (archive.apache.org or struts.apache.org).
- 3. Replace the struts-core-*.jar file in your application's WEB-INF/lib directory with the new version.
- 4. Update any build configuration files (pom.xml, build.gradle, etc.) to reference Struts 1.2.9 or newer.
- 5. Rebuild and redeploy the application.
- 6. Verify the application functions correctly and test the multipart form functionality.
Generated from the published advisory — verify against the referenced sources before acting.
