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
A vulnerability classified as critical has been found in Software AG WebMethods 10.11.x/10.15.x. Affected is an unknown function of the file wm.server/connect/. The manipulation leads to improper access controls. It is possible to launch the attack remotely. To access a file like /assets/ a popup may request username and password. By just clicking CANCEL you will be redirected to the directory. If you visited /invoke/wm.server/connect, you'll be able to see details like internal IPs, ports, and versions. In some cases if access to /assets/ is refused, you may enter /assets/x as a wrong value, then come back to /assets/ which we will show the requested data. It appears that insufficient access control is depending on referrer header data. VDB-247158 is the identifier assigned to this vulnerability. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.

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 · moderate confidence

Improper access control vulnerability in Software AG WebMethods allows unauthenticated remote attackers to bypass authentication by manipulating HTTP referrer headers or canceling authentication prompts. The vulnerability affects the wm.server/connect/ endpoint and allows access to sensitive internal information including IPs, ports, and version details.

MitigationUntil vendor patch is available, implement network segmentation to restrict access to affected endpoints, deploy WAF rules to detect and block referrer header manipulation attempts, and consider disabling or restricting access to the wm.server/connect/ endpoint if not required for business functions.

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 Software AG WebMethods installation
    Locate WebMethods installation directories or check for webMethods-related services running on the server. Common installation paths include /opt/softwareag or C:\SoftwareAG on Windows.
    Affected if Software AG WebMethods is present on the system
  2. Check WebMethods version
    Access the WebMethods admin console or check version files within the installation directory. The version is typically displayed in the admin UI or in product-specific configuration files.
    Affected if Installed version falls within 10.11.0 through 10.11.4 or 10.15.0 through 10.15.4
  3. Verify wm.server/connect endpoint accessibility
    Attempt to access the wm.server/connect/ endpoint via HTTP/HTTPS request to the WebMethods server (e.g., http://<server>/wm.server/connect/). Check if the endpoint responds without requiring authentication.
    Affected if The endpoint is accessible and responds to unauthenticated requests
  4. Test for authentication bypass
    Send a request to the wm.server/connect/ endpoint with a manipulated HTTP Referrer header or by canceling authentication prompts. Observe if sensitive information (IPs, ports, version details) is returned without proper authentication.
    Affected if The endpoint returns sensitive internal information without successful authentication

A system is affected if it runs Software AG WebMethods versions 10.11.0-10.11.4 or 10.15.0-10.15.4 with the wm.server/connect/ endpoint exposed and accessible without proper authentication.

Upgrade available Upgrade to a release after 10.15.4
Interim mitigation

Until vendor patch is available, implement network segmentation to restrict access to affected endpoints, deploy WAF rules to detect and block referrer header manipulation attempts, and consider disabling or restricting access to the wm.server/connect/ endpoint if not required for business functions.

Recommended fix Moderate confidence

WebMethods 10.15.5 or later stable release

  1. 1. Identify all WebMethods instances running versions 10.11.x (up to 10.11.4) or 10.15.x (up to 10.15.4) in the environment
  2. 2. Review the current access control configuration for the /wm.server/connect/ and /assets/ endpoints
  3. 3. Implement network-level restrictions to limit access to sensitive endpoints, allowing only trusted IP ranges or VPN-accessible networks
  4. 4. If available from Software AG support, request the security hotfix for this vulnerability
  5. 5. Plan an upgrade to the latest stable WebMethods release (beyond 10.15.4) which should include the fix for this improper access control issue
  6. 6. After upgrade, verify that authentication is properly enforced on /wm.server/connect/ and /assets/ endpoints - cancelling the auth dialog should not grant access
  7. 7. Test that internal information (IPs, ports, versions) is no longer exposed without valid authentication
Caveat Review Software AG release notes for migration path from 10.11.x or 10.15.x to ensure compatibility with custom integrations and dependencies
