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 crafted HTTP packet with a missing HTTP URI can create a denial-of-service condition in Softing Secure Integration Server V1.22.

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

A denial-of-service vulnerability exists in Softing Secure Integration Server V1.22 where the server fails to properly handle HTTP requests lacking a URI component. When the server processes a specially crafted HTTP packet with a missing URI, it enters a denial-of-service condition, potentially making the service unavailable.

MitigationApply available patches or updates from Softing for Secure Integration Server V1.22. Until a patch is available, consider implementing network-level filtering to block malformed HTTP requests or deploying the server behind a reverse proxy that validates HTTP request structure.

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 installed Softing product
    Locate Softing Secure Integration Server, Edgeaggregator, Edgeconnector, OPC, UAGates, or OPC UA C++ SDK installations on the system. Check installed programs, services, or application directories for Softing components.
    Affected if Any Softing product from the affected list is installed on the system.
  2. Determine installed version
    Access the product's version information through its UI, service properties, or check the binary/dll version properties. For Secure Integration Server, verify the exact version number.
    Affected if The installed version matches exactly: Secure Integration Server 1.22, Edgeaggregator 3.1, Edgeconnector 3.1, OPC 5.2, OPC UA C++ SDK 6, or UAGates 1.74.
  3. Verify HTTP service is exposed
    Confirm the Softing service exposes an HTTP interface. Check network listeners, firewall rules, or service configuration for HTTP port availability (common ports: 80, 443, 8080, 8443).
    Affected if The product runs an HTTP service that accepts external or internal HTTP connections.
  4. Test HTTP request handling
    Send a raw HTTP request without a URI component (for example: 'GET / HTTP/1.1\r\nHost: target\r\n\r\n' with the '/' and path removed) to the service endpoint and observe the response or service availability.
    Affected if The service becomes unresponsive, crashes, or fails to properly respond after receiving an HTTP request with a missing URI component.
  5. Check service stability
    Monitor the Softing service process for unexpected termination or inability to accept new connections after processing malformed HTTP traffic.
    Affected if The service enters a denial-of-service condition and cannot recover without restart.

The environment is affected if a Softing product version 1.22 (Secure Integration Server), 3.1 (Edgeaggregator/Edgeconnector), 5.2 (OPC), 6 (OPC UA C++ SDK), or 1.74 (UAGates) is installed with an exposed HTTP interface that fails when processing requests lacking a URI component.
