CVE-2014-2142
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 ONS 15454 controller cards with software 10.0 and earlier allow remote attackers to cause a denial of service (card reload) via a crafted HTTP URI, aka Bug ID CSCun06870.
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 vulnerability exists in Cisco ONS 15454 controller cards running software version 10.0 or earlier. Attackers can trigger a denial of service by sending a specially crafted HTTP URI request to the affected device, causing the controller card to reload and interrupt services.

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 Cisco ONS 15454 hardwareLog into the device or check inventory to confirm the device model is Cisco ONS 15454. This vulnerability affects controller cards in this specific optical networking platform.Affected if Device is not a Cisco ONS 15454 system - the vulnerability does not apply.
-
Retrieve software version from controller cardAccess the controller card CLI or web interface and retrieve the running software version. In the CLI, this is typically shown via 'show version' or similar command. The version appears as a number like 9.x or 10.x.Affected if Unable to retrieve version - verify access to the controller card.
-
Compare version against affected rangeCompare the installed version to the affected list: 9.0, 9.1, 9.2, 9.2.1, 9.2.2, 9.3, 9.4, 9.6, 9.8, or any version 10.0 or earlier.Affected if Version is 10.0 or earlier (9.0 through 10.0 inclusive) - the device is running a vulnerable version.
-
Verify HTTP service is enabledCheck the controller card configuration to see if HTTP or web management interface is enabled. This is typically found in the device web interface settings or via 'show running-config' looking for HTTP service configuration.Affected if HTTP is disabled or blocked, the attack surface may be reduced but the vulnerable code still exists in the software.
A user is affected if they have a Cisco ONS 15454 controller card running software version 10.0 or earlier with HTTP service enabled, as the specially crafted HTTP URI request can trigger a controller reload.

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 ONS 15454 controller card software to a version newer than 10.0 (e.g., 10.1 or later) that addresses this vulnerability. If upgrades are not immediately feasible, restrict HTTP access to these devices using network segmentation or firewall rules to prevent untrusted external access.
