CVE-2018-15617
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 · uneditedA vulnerability in the "capro" (Call Processor) process component of Avaya Aura Communication Manager could allow a remote, unauthenticated user to cause denial of service. Affected versions include 6.3.x, all 7.x versions prior to 7.1.3.2, and all 8.x versions prior to 8.0.1.
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 · high confidenceA remote, unauthenticated attacker can send specially crafted requests to the capro (Call Processor) process in Avaya Aura Communication Manager, causing the process to fail and resulting in denial of service for call processing capabilities.

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 Avaya Aura Communication Manager versionAccess the system via CLI or admin interface and run 'show version' or check system properties to obtain the installed Communication Manager version numberAffected if the version falls within 6.3.0.1-6.3.17.0, 7.0-7.1.3.1, or 8.0-8.0.0 ranges
-
Verify capro process is enabledConfirm the capro (Call Processor) process is running on the system via process list or service status commandAffected if the capro process is active and handling call processing requests
-
Check network accessibility of the capro serviceDetermine if the capro service port is exposed to untrusted networks by reviewing firewall rules, network interfaces, and listening servicesAffected if the capro service port is reachable from external or untrusted networks without proper filtering
-
Confirm unauthenticated access is possibleVerify that the capro process accepts requests without requiring authentication by reviewing service configurationAffected if the capro service accepts unauthenticated requests (default behavior for this vulnerability)
A system is affected if it runs a vulnerable Avaya Aura Communication Manager version within the listed ranges with the capro process exposed to the network.

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 data7.1.3.28.0.1
Upgrade Avaya Aura Communication Manager to version 7.1.3.2 or later for 7.x branches, or 8.0.1 or later for 8.x branches. For 6.3.x systems, upgrade to a supported version. Apply during a planned maintenance window with backups and failover measures in place.
