CVE-2019-1631
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 Integrated Management Controller (IMC) could allow an unauthenticated, remote attacker to access potentially sensitive system usage information. The vulnerability is due to a lack of proper data protection mechanisms. An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected device. A successful exploit could allow an attacker to view sensitive system data.
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 vulnerability in Cisco IMC web-based management interface allows unauthenticated remote attackers to access sensitive system usage information via crafted HTTP requests. The root cause is insufficient data protection mechanisms in the web interface.

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 IMC installationAccess the system's management interface CLI or check firmware version using `show version` or `ipmitool -I lanplus -H <imc_ip> -U admin -P <password> raw` commands to retrieve version informationAffected if The system is running Cisco Integrated Management Controller (any version)
-
Identify Cisco UCS versionCheck the Cisco Unified Computing System version via IMC interface or CLI using `show version` or through the UCS Manager if availableAffected if The UCS version is exactly 4.0(1c)hs3
-
Verify web-based management interface is enabledCheck IMC configuration for web interface status via CLI: `scope ipmi` then `show detail` or via IMC web UI under 'Server' > 'Summary' > 'Management Interfaces'Affected if The Cisco IMC web-based management interface is enabled and accessible
-
Confirm web interface network exposureReview network access controls, firewall rules, or ACLs protecting the IMC web interface (typically ports 80/443 or 4433). Use `show network` or `show ipmi access` from IMC CLIAffected if The IMC web interface is reachable from untrusted networks (not restricted to trusted IPs)
Your environment is affected if you run Cisco IMC (any version) or UCS version 4.0(1c)hs3 with the web-based management 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 relevant Cisco firmware/software update for Cisco IMC that addresses this vulnerability. If immediate patching is not possible, restrict network access to the management interface to trusted IPs only.
