CVE-2013-1236
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 · uneditedCisco TelePresence Supervisor MSE 8050 before 2.3(1.31) allows remote attackers to cause a denial of service (CPU consumption or device reload) by establishing TCP connections at a high rate, aka Bug IDs CSCuf76076 and CSCuf79763.
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 denial of service vulnerability in Cisco TelePresence Supervisor MSE 8050 firmware versions before 2.3(1.31) allows unauthenticated remote attackers to exhaust CPU resources or trigger device reload by establishing TCP connections at an abnormally high rate.

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 the device firmware versionAccess the Cisco TelePresence Supervisor MSE 8050 administrative interface or use the CLI command 'show version' to retrieve the current firmware versionAffected if The installed firmware version is 2.2(1.17) or earlier, or if the device is any version prior to 2.3(1.31)
-
Verify network accessibility of the deviceScan the network to confirm the TelePresence Supervisor is reachable via TCP on its management or signaling ports from network segments accessible to untrusted usersAffected if The device accepts TCP connections from untrusted or external network segments without strict access controls
-
Check for upstream rate-limiting controlsInspect upstream network devices (firewalls, routers, IDS/IPS) for rate-limiting rules or connection throttling configured to limit the TCP connection rate toward the TelePresence SupervisorAffected if No rate-limiting or connection rate controls are implemented on inbound TCP traffic to the device
A user is affected if their Cisco TelePresence Supervisor MSE 8050 is running firmware version 2.2(1.17) or earlier, is network-accessible to untrusted parties, and lacks upstream connection rate limiting.

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 dataUpgrade Cisco TelePresence Supervisor MSE 8050 firmware to version 2.3(1.31) or later. As an interim control, implement rate-limiting on upstream network devices to restrict incoming TCP connection rates.
