CVE-2019-0404
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 · uneditedSAP Enable Now, before version 1911, leaks information about network configuration in the server error messages, leading to Information Disclosure.
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 confidenceSAP Enable Now versions before 1911 contain an information disclosure vulnerability where server error messages reveal network configuration details about the system. This exposure could provide attackers with valuable intelligence about the target environment's network topology and configuration.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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.
-
Identify installed SAP Enable Now versionLocate the version information in the SAP Enable Now administrative interface, installation directory, or by querying the server's about/version endpoint. Common locations include the management console or server metadata files.Affected if The version displayed is earlier than 1911 (for example, 1905, 10.5, etc.)
-
Compare version to affected rangeVerify the exact version number against the threshold. Versions before 1911 are affected; version 1911 and later are not.Affected if The installed version is any release prior to 1911 in the version numbering scheme used by SAP Enable Now
-
Trigger test error and inspect responseGenerate a deliberate error condition on the SAP Enable Now server (such as an invalid request or malformed input) and capture the server's error response. Inspect the error message content for network details.Affected if The returned error message contains internal IP addresses, hostnames, network paths, server names, or other network configuration information that should not be externally visible
You are affected if SAP Enable Now is installed at a version earlier than 1911 AND server error responses expose network configuration details about the system.
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.
From vendor data1911
Upgrade SAP Enable Now to version 1911 or later to obtain the patch. Additionally, review custom error handling configurations to ensure server responses do not expose sensitive network information.
