CVE-2017-12297
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 Cisco WebEx Meeting Center could allow an authenticated, remote attacker to initiate connections to arbitrary hosts, aka a "URL Redirection Vulnerability." The vulnerability is due to insufficient access control for HTTP traffic directed to the Cisco WebEx Meeting Center. An attacker could exploit this vulnerability by sending a malicious URL to the Cisco WebEx Meeting Center. An exploit could allow the attacker to connect to arbitrary hosts. Cisco Bug IDs: CSCvf63843.
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 confidenceThis is a Server-Side Request Forgery (SSRF) vulnerability in Cisco WebEx Meeting Center where insufficient access controls on HTTP traffic allow an authenticated attacker to send malicious URLs that cause the server to initiate connections to arbitrary hosts. The attacker can leverage this to potentially reach internal services, perform port scanning, or attack internal systems that the WebEx server can access.

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 installed Cisco WebEx Meeting Center versionAccess the WebEx administrative interface or check system documentation to locate the installed version number of Cisco WebEx Meeting CenterAffected if The installed version matches one of the following: t30, t31, t32, t32.3, t32.4, t32.6, t32.7, or t32.8
-
Confirm WebEx Meeting Center service is activeVerify that the Cisco WebEx Meeting Center application is running and accessible on the networkAffected if The service is running and the version falls within the affected versions listed above
-
Review HTTP request handling configurationExamine the WebEx Meeting Center configuration files or administrative settings related to URL handling and HTTP request processingAffected if The server allows arbitrary URL inputs from authenticated users without proper validation or restrictions
-
Audit outbound network connections from the WebEx serverUse network monitoring tools or firewall logs to review outbound HTTP/HTTPS connections initiated by the WebEx serverAffected if Outbound connections are made to unexpected or internal hosts that were not initiated by legitimate meeting activities
-
Check authentication and access control settingsReview user authentication settings and access control policies within the WebEx administrative console to determine if unauthenticated or low-privilege users can submit URL requestsAffected if Authenticated users have the ability to submit arbitrary URLs through the WebEx service without sufficient restrictions
A system is affected if it is running Cisco WebEx Meeting Center version t30, t31, t32, t32.3, t32.4, t32.6, t32.7, or t32.8, and the WebEx service is accessible to authenticated users who can submit HTTP requests.

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 vendor patch from Cisco (Bug ID CSCvf63843) when available, or upgrade to a fixed version of Cisco WebEx Meeting Center. Until patched, monitor outbound connections from the WebEx server for anomalous behavior.
