CVE-2019-12000
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 · uneditedHPE has found a potential Remote Access Restriction Bypass in HPE MSE Msg Gw application E-LTU prior to version 3.2 when HTTPS is used between the USSD and an external USSD service logic application. Update to version 3.2 and update the HTTPS configuration as described in the HPE MSE Messaging Gateway Configuration and Operations Guide.
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 confidenceThis is a Remote Access Restriction Bypass vulnerability in HPE MSE Messaging Gateway application E-LTU versions prior to 3.2. The vulnerability manifests when HTTPS is configured between the USSD (Unstructured Supplementary Service Data) component and an external USSD service logic application, where the HTTPS configuration fails to properly restrict remote access, potentially allowing unauthorized access to messaging gateway 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 checksWork through these to decide whether this CVE applies to you.
-
Confirm HPE MSE Messaging Gateway E-LTU installation and versionLocate the HPE MSE Messaging Gateway installation directory and check the version information, typically found in the product documentation, about screen, or version file within the installation folderAffected if The installed version is below 3.2
-
Identify if USSD component is configuredAccess the HPE MSE Messaging Gateway administrative console or configuration files and look for USSD (Unstructured Supplementary Service Data) component settingsAffected if USSD component is configured and enabled in the environment
-
Verify HTTPS configuration between USSD and external serviceExamine the HPE MSE Messaging Gateway configuration files or admin interface for HTTPS settings associated with the USSD component connection to external USSD service logic applicationsAffected if HTTPS is configured for the USSD component communication pathway
-
Inspect remote access restriction settings in HTTPS configReview the HTTPS configuration for the USSD pathway and check whether remote access restriction controls are properly defined and enforcedAffected if The HTTPS configuration lacks proper remote access restrictions or allows unrestricted access
Environment is affected if HPE MSE Messaging Gateway E-LTU version is below 3.2 AND USSD component is configured with HTTPS to an external service but remote access restrictions are not properly enforced in the HTTPS 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 data3.2
Update HPE MSE Messaging Gateway to version 3.2 and reconfigure HTTPS settings according to the HPE MSE Messaging Gateway Configuration and Operations Guide to ensure proper access restrictions are enforced.
