CVE-2017-12264
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 Web Admin Interface of Cisco Meeting Server could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. The vulnerability is due to insufficient bound checks performed by the affected software. An attacker could exploit this vulnerability by sending a malicious HTTP packet to the affected system. A successful exploit could allow the attacker to cause a reload of the Web Admin Server. Cisco Bug IDs: CSCve89149.
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 denial of service vulnerability in the Cisco Meeting Server Web Admin Interface allows unauthenticated remote attackers to send malicious HTTP packets that trigger insufficient bound checks, causing the Web Admin Server to reload. The vulnerability requires no authentication and is exploited via specially crafted HTTP requests.

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 Cisco Meeting Server is deployedIdentify if Cisco Meeting Server software is running on the system. Check for CMS-related processes such as callbridge, webadmin, or the cms command-line tool. On the server, run 'ps aux | grep -i cms' or list installed packages.Affected if Cisco Meeting Server is installed and running on the system
-
Verify Web Admin Interface is enabledDetermine if the Web Admin service is active and listening for connections. Use netstat or ss to check if port 443, 8443, or the configured admin port is in LISTEN state, for example: 'ss -tlnp | grep -E "(443|8443)"' or check the CMS configuration.Affected if Web Admin Interface is enabled and listening on a network port
-
Assess network exposure of Web Admin InterfaceReview firewall rules, network ACLs, or cloud security group configurations to determine if the Web Admin port is open to untrusted IP addresses or broad network ranges. Check for rules allowing traffic from 0.0.0.0/0 or non-internal subnets.Affected if Web Admin Interface is reachable from untrusted or public IP addresses
-
Look for evidence of service restartsReview system logs and Web Admin service logs for unplanned reloads or crashes. Check timestamps for sudden Web Admin restarts that were not initiated by administrators.Affected if Unexplained Web Admin service reloads are occurring
A system is vulnerable if Cisco Meeting Server is running with the Web Admin Interface enabled and exposed to untrusted network access.

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 dataApply the Cisco patch for bug CSCve89149. As an interim measure, restrict network access to the Web Admin Interface to trusted IP addresses or networks to reduce attack surface.
