CVE-2014-8034
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 Meetings Server 1.5 presents the same CAPTCHA challenge for each login attempt, which makes it easier for remote attackers to obtain access via a brute-force approach of guessing usernames, aka Bug ID CSCuj40321.
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 Meetings Server 1.5 uses a static CAPTCHA that does not change between login attempts. Attackers can solve the CAPTCHA once and reuse the same challenge-response pair for unlimited brute-force attempts, enabling username enumeration and potential unauthorized 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.
-
Confirm Cisco WebEx Meetings Server installationIdentify if Cisco WebEx Meetings Server is installed in your environment. This is typically a web-based conferencing platform that would be accessible via its web portal URL.Affected if The product is not Cisco WebEx Meetings Server, then this CVE does not apply.
-
Check installed versionDetermine the exact version number of the installed Cisco WebEx Meetings Server. Consult your product documentation for the appropriate command or admin interface to retrieve version information.Affected if The version is 1.5 exactly, then the product is in the affected version range.
-
Test CAPTCHA behavior between login attemptsAttempt multiple login attempts to the WebEx Meetings Server login page. For each attempt, observe whether the CAPTCHA image and its challenge value change. Submit the same solved CAPTCHA value repeatedly to see if it remains valid across multiple attempts.Affected if The CAPTCHA image and challenge remain identical across different login attempts, and the same solved CAPTCHA value can be reused, indicating a static CAPTCHA that does not change between attempts.
-
Verify CAPTCHA session bindingExamine whether the CAPTCHA challenge is bound to the session and invalidated after each login attempt. Attempt to use a previously solved CAPTCHA after closing and reopening the browser session.Affected if The CAPTCHA does not change or invalidate after each login attempt or session, confirming the static CAPTCHA vulnerability.
You are affected if you have Cisco WebEx Meetings Server version 1.5 installed and the CAPTCHA challenge remains static across multiple login attempts without generating a new challenge for each attempt.

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 dynamic CAPTCHA generation that presents a new challenge for each login attempt. The CAPTCHA token/validation should be tied to the session and invalidated after each use.
