CVE-2014-3304
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 · uneditedThe OutlookAction Class in Cisco WebEx Meetings Server allows remote attackers to enumerate user accounts by entering crafted URLs and examining the returned messages, aka Bug ID CSCuj81722.
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 confidenceThe OutlookAction Class in Cisco WebEx Meetings Server contains a user enumeration vulnerability. Remote attackers can submit crafted URLs containing potential usernames and differentiate valid from invalid accounts by analyzing the distinct error messages or responses returned by the server, allowing complete user enumeration.

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 Meetings Server installationCheck for running processes or services related to WebEx, or look for web server responses on common ports (443, 4443) that identify themselves as Cisco WebEx Meetings ServerAffected if The server is running and accessible on the network
-
Locate the OutlookAction endpointAttempt to access the /OutlookAction or similar WebEx client endpoints by submitting HTTP requests to the serverAffected if The server responds to OutlookAction or WebEx client-related URLs with any response
-
Test for user enumeration via differential responsesSubmit crafted requests with multiple potential usernames (e.g., different email formats or known internal usernames) and analyze the HTTP response codes, error messages, or response timing for differences between valid and invalid accountsAffected if The server returns distinct error messages, different HTTP status codes, or measurably different responses for valid usernames versus invalid ones
-
Verify uniform error handling is not implementedCompare error responses from the OutlookAction endpoint for both valid and invalid usernames to confirm they are not identicalAffected if Error responses differ between valid and invalid usernames, indicating the vulnerability is present
The environment is affected if Cisco WebEx Meetings Server is running and the OutlookAction endpoint returns distinguishable responses for valid versus invalid usernames, allowing user enumeration.

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 dataImplement uniform error responses that return identical messages regardless of user validity, or deploy rate limiting and account lockout policies to mitigate automated enumeration attempts. Apply vendor patches when available.
