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-based management interface of Cisco IOS and Cisco IOx Software could allow an unauthenticated, remote attacker to view confidential information that is displayed without authenticating to the device. Affected Products: This vulnerability affects Cisco IOS Software and Cisco IOx Software running on IR829, IR809, IE4K, and CGR1K platforms. More Information: CSCvb20897. Known Affected Releases: 1.0(0).
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 confidenceAn information disclosure vulnerability in the web-based management interface of Cisco IOS and IOx Software allows unauthenticated remote attackers to view confidential information without authenticating to the device. The vulnerability affects specific industrial router platforms (IR829, IR809, IE4K, CGR1K) running affected software versions.

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 device modelUse the command 'show version' or physically identify the router model. Valid affected models are: IR829, IR809, IE4K, and CGR1K.Affected if The device is an IR829, IR809, IE4K, or CGR1K industrial router
-
Identify IOx software versionExecute 'show iox' or 'show version | include IOx' to determine the installed IOx version.Affected if The IOx version is exactly 1.0(0)
-
Check if web management interface is enabledRun 'show running-config | include ip http' or 'show ip interface' to see if the HTTP/HTTPS management server is configured.Affected if HTTP server or HTTP secure-server is enabled in the configuration
-
Verify network exposure of web interfaceReview interface configurations and ACLs using 'show access-lists' and 'show ip interface brief' to determine if the web interface is reachable from outside the trusted network.Affected if The web-based management interface is accessible from untrusted networks
A device is affected if it is an IR829, IR809, IE4K, or CGR1K router running Cisco IOx version 1.0(0) with the HTTP/HTTPS management interface enabled and 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 dataApply the Cisco patch or upgrade to a fixed software release. If no patch is immediately available, restrict network access to the web-based management interface using ACLs or firewall rules to prevent unauthorized external access.
