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
Certain WSO2 products allow unrestricted file upload with resultant remote code execution. The attacker must use a /fileupload endpoint with a Content-Disposition directory traversal sequence to reach a directory under the web root, such as a ../../../../repository/deployment/server/webapps directory. This affects WSO2 API Manager 2.2.0 up to 4.0.0, WSO2 Identity Server 5.2.0 up to 5.11.0, WSO2 Identity Server Analytics 5.4.0, 5.4.1, 5.5.0 and 5.6.0, WSO2 Identity Server as Key Manager 5.3.0 up to 5.11.0, WSO2 Enterprise Integrator 6.2.0 up to 6.6.0, WSO2 Open Banking AM 1.4.0 up to 2.0.0 and WSO2 Open Banking KM 1.4.0, up to 2.0.0.

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

WSO2 products contain an unrestricted file upload vulnerability in /fileupload endpoints. Attackers exploit this by including directory traversal sequences (../../../) in the Content-Disposition header to write malicious files (e.g., JSP webshells) to web-accessible directories under the web root, specifically the repository/deployment/server/webapps folder, achieving remote code execution.

MitigationApply vendor-provided security patches or upgrade to fixed versions; if patching is immediately unavailable, block or restrict access to /fileupload endpoints via WAF rules or network segmentation, and ensure uploaded files in web-accessible directories cannot be executed.

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 WSO2 product and version
    Locate the version file in your WSO2 installation (typically in the product's root directory or repository/conf/etc), or query the admin console/metadata endpoint for the running version
    Affected if The installed version falls within any of these ranges: API Manager 2.2.0-4.0.0, Enterprise Integrator 6.2.0-6.6.0, Identity Server 5.2.0-5.11.0, Identity Server Analytics 5.4.0/5.4.1/5.5.0/5.6.0, Identity Server as Key Manager 5.3.0-5.10.0, Open Banking AM 1.3.0-2.0.0, Open Banking IAM 2.0.0, or Op
  2. Verify /fileupload endpoint exposure
    Attempt a local curl request to the fileupload endpoint (e.g., POST to /fileupload/toolsAny) or check your reverse proxy/firewall rules to determine if these endpoints are accessible from untrusted networks
    Affected if The /fileupload endpoints are reachable from outside trusted networks without authentication controls
  3. Inspect webapps directory for unauthorized files
    Examine the webapps directory (repository/deployment/server/webapps or similar deployment path) for unexpected .jsp files with suspicious names, especially those not deployed through standard WSO2 tooling
    Affected if Unexpected .jsp files exist in the webapps directory that were not intentionally deployed by administrators
  4. Review access logs for exploitation patterns
    Search HTTP access logs (found in repository/logs/http_access_*.log) for requests to /fileupload endpoints containing directory traversal sequences (../) in Content-Disposition headers or unusual file extensions
    Affected if Logs contain POST requests to /fileupload with ../../ sequences in headers or uploaded .jsp files to non-standard paths

You are affected if you run any WSO2 product version within the listed ranges AND your /fileupload endpoints are network-accessible, or if you find unexpected JSP files in your webapps directory or exploitation attempts in your logs.

Upgrade available Upgrade to a release after 6.6.0
Interim mitigation

Apply vendor-provided security patches or upgrade to fixed versions; if patching is immediately unavailable, block or restrict access to /fileupload endpoints via WAF rules or network segmentation, and ensure uploaded files in web-accessible directories cannot be executed.

Recommended fix High confidence

Upgrade to the latest stable release of your WSO2 product (e.g., API Manager 4.0.1+, EI 6.6.1+, IS 5.11.1+, IS Analytics 5.7.0+, IS as KM 5.11.1+, Open Banking AM/KM 2.0.1+)

  1. 1. Identify the specific WSO2 product and current version from the affected list (API Manager, Enterprise Integrator, Identity Server, etc.)
  2. 2. Determine the appropriate fixed version for your product: API Manager upgrade to 4.0.1 or later; Enterprise Integrator upgrade to 6.6.1 or later; Identity Server upgrade to 5.11.1 or later; Identity Server Analytics upgrade to 5.7.0 or later; Identity Server as Key Manager upgrade to 5.11.1 or later; Open Banking AM upgrade to 2.0.1 or later; Open Banking KM upgrade to 2.0.1 or later
  3. 3. Review WSO2 security advisories at security.docs.wso2.com for any specific patch requirements for your exact version
  4. 4. Create a backup of the current installation including repository/deployment directory
  5. 5. Test the upgrade in a staging environment before production deployment
  6. 6. Upgrade the production environment to the fixed version
  7. 7. Verify the /fileupload endpoints no longer accept directory traversal sequences (../) in Content-Disposition headers
  8. 8. After upgrade, confirm web applications deploy correctly in repository/deployment/server/webapps
