CVE-2024-43107
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 · uneditedImproper Certificate Validation (CWE-295) in the Gallagher Milestone Integration Plugin (MIP) permits unauthenticated messages (e.g. alarm events) to be sent to the Plugin. This issue effects Gallagher MIPS Plugin v4.0 prior to v4.0.32, all versions of v3.0 and prior.
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 confidenceThe Gallagher Milestone Integration Plugin (MIP) fails to properly validate SSL/TLS certificates (CWE-295), allowing attackers to send unauthenticated messages such as alarm events to the plugin by presenting invalid or forged certificates. This enables spoofing of legitimate alarm events and potential disruption of security monitoring workflows.

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.
-
Verify Gallagher MIP is installedCheck system for the Gallagher Milestone Integration Plugin - look for MIP software in Programs and Features, services, or installed applications listAffected if The plugin is present on the system
-
Identify MIP version numberOpen the MIP application or check its About/Properties window to find the installed version number, or query the Windows Registry under HKLM\SOFTWARE\Gallagher\MIP for the Version valueAffected if Version displays a number lower than 4.0.32 or cannot be determined (indicating very old installation)
-
Confirm SSL/TLS integration is enabledExamine MIP configuration settings or logs to verify SSL/TLS communication with Milestone is configured and activeAffected if SSL/TLS is enabled - the certificate validation flaw only applies when encrypted communication is in use
-
Compare version to affected rangeCompare the installed version against known affected versions: any version prior to 4.0.32 (including all v3.x and earlier releases) is vulnerableAffected if Installed version is 4.0.31 or lower, or version cannot be verified and the product is known to be v3.0 or older
The environment is affected if the Gallagher MIP version is 4.0.31 or lower (v3.0 or prior) and SSL/TLS integration with Milestone is configured and enabled.

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.
dbcve · scopedUpgrade the Gallagher MIPS Plugin to version 4.0.32 or later to obtain the proper certificate validation fix. Organizations running v3.0 or prior should plan an upgrade path to v4.0.32.
v4.0.32 or later
- Identify the current version of the Gallagher Milestone Integration Plugin (MIP) by checking the plugin documentation or system configuration
- If the installed version is v4.0 prior to v4.0.32, or any version of v3.0 or prior, upgrade the plugin to version v4.0.32 or later
- After upgrading, verify that the new version is running by checking the plugin version in the Milestone system
- Test that alarm events and other communications are functioning correctly with the updated plugin
