CVE-2014-2166
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 · uneditedThe SIP implementation in Cisco TelePresence TC Software 4.x and TE Software 4.x allows remote attackers to cause a denial of service (device reload) via crafted SIP packets, aka Bug ID CSCto70562.
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 SIP implementation in Cisco TelePresence TC Software 4.x and TE Software 4.x contains a vulnerability where specially crafted SIP packets sent to the device cause a denial of service via forced device reload. This is a remote, unauthenticated network-based attack targeting the SIP protocol handler.

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 installed Cisco TelePresence software versionAccess the device via its web interface or API and locate the software version information, typically found in the system status or diagnostics section. Alternatively, use the device's command-line interface and query the current software version.Affected if The installed version matches one of the following: TC Software 4.0.0, 4.0.1, 4.0.4, 4.1.1, 4.1.2, 4.2.0, 4.2.1, 4.2.2, 4.2.3, 4.2.4; or TE Software 4.1.0, 4.1.1, 4.1.2, 4.1.3
-
Determine if SIP protocol handling is enabledAccess the device configuration and locate the SIP settings. Check whether the SIP feature or profile is activated on the device. This is typically found in the device's network or protocol configuration settings.Affected if SIP is enabled or configured on the device, as the vulnerability resides in the SIP implementation and requires SIP to be active for the attack to trigger the reload.
-
Assess network exposure of the SIP serviceReview the device's network configuration and firewall rules to determine if the SIP port (typically UDP/TCP 5060) is accessible from untrusted or external network segments. Verify whether the device accepts SIP packets from unauthenticated or unknown sources.Affected if The SIP service is reachable from untrusted network sources or the device is directly exposed to the network without restrictive access controls, enabling remote unauthenticated attackers to send malicious SIP packets.
The device is affected if it runs any of the listed TC or TE software versions AND has SIP enabled AND is accessible to remote attackers on 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 dataApply the Cisco patch for this vulnerability (refer to Cisco bug ID CSCto70562). If patching is delayed, implement network segmentation to restrict SIP traffic to trusted sources and reduce attack surface.
