CVE-2015-4207
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 WebEx Meeting Center places a meeting's access number in a URL, which allows remote attackers to obtain sensitive information and bypass intended attendance restrictions by visiting a meeting-registration page, aka Bug ID CSCus62147.
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 confidenceCisco WebEx Meeting Center incorrectly places meeting access numbers directly in URL parameters. This exposes sensitive meeting credentials which can be captured from browser history, proxy logs, or referrer headers. Attackers can use these exposed access numbers to bypass attendance restrictions and gain unauthorized access to meeting registration pages.

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 WebEx Meeting Center installationCheck if Cisco WebEx Meeting Center is deployed in your environment by reviewing installed software, web server configurations, or service inventory for 'Cisco WebEx Meeting Center'Affected if Cisco WebEx Meeting Center is present in the environment
-
Inspect browser history for meeting URLsReview browser history or saved bookmarks for WebEx meeting URLs that may contain access numbers in query parameters (look for patterns like '?accessnumber=' or '?meeting=' in URLs containing 'webex' domain)Affected if Browser history contains WebEx URLs with meeting credentials exposed in URL parameters
-
Review proxy and web server logsExamine proxy server logs, web server access logs, or WAF logs for incoming requests to WebEx URLs where access numbers or meeting IDs appear as URL query parametersAffected if Logs contain WebEx meeting URLs with sensitive identifiers in URL query strings
-
Check referrer header logsInspect server logs that capture HTTP referrer headers for instances where WebEx URLs with access numbers in parameters were passed to third-party sitesAffected if Referrer logs show WebEx meeting URLs with exposed access numbers being sent to external sites
-
Verify URL-based authentication configurationReview WebEx configuration to determine if meeting access numbers and credentials are being passed via URL parameters rather than POST-based or session-based authenticationAffected if WebEx is configured to pass meeting access credentials through URL query parameters
A user is affected if Cisco WebEx Meeting Center is deployed and meeting access credentials are exposed in URL parameters that can be captured from browser history, proxy logs, or referrer headers.

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 Cisco's vendor patch for this vulnerability (CSCus62147) to ensure access numbers are not exposed in URLs. Consider using POST-based authentication or session tokens instead of URL parameters for meeting access.
