CVE-2015-4057
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 "Plug-in for VMware vCenter" in VCE Vision Intelligent Operations before 2.6.5 sends a cleartext HTTP response upon a request for the Settings screen, which allows remote attackers to discover the admin user password by sniffing the network.
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 VMware vCenter plug-in in VCE Vision Intelligent Operations before version 2.6.5 transmits the admin user password in cleartext HTTP when accessing the Settings screen, allowing remote attackers on the same network to intercept and discover the password via traffic sniffing.

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.
-
Check installed VCE Vision Intelligent Operations versionAccess the VCE Vision Intelligent Operations admin interface or check the installed package version through the vCenter plug-in management panel. Look for the version number displayed in the About or System Information section.Affected if The installed version is 2.6.4 or earlier.
-
Verify network protocol used for Settings accessObserve the URL when navigating to the Settings screen in the VCE Vision plug-in. Check if the connection uses HTTP (http://) instead of HTTPS (https://).Affected if The Settings screen is accessed over plain HTTP rather than encrypted HTTPS.
-
Inspect browser or network trace for cleartext credentialsUse browser developer tools or a network packet capture tool (such as Wireshark) to monitor network traffic when accessing the Settings screen. Look for HTTP POST or GET requests containing the admin password in cleartext.Affected if HTTP traffic contains the admin user password in plaintext within request parameters or body.
-
Check vCenter plug-in configuration for SSL/TLS enforcementExamine the VCE Vision plug-in configuration settings within vCenter to determine if HTTPS enforcement is enabled or if HTTP fallback is permitted.Affected if HTTPS is not enforced or HTTP is allowed as a valid connection method for the plug-in.
You are affected if VCE Vision Intelligent Operations is version 2.6.4 or earlier AND the Settings screen transmits credentials over unencrypted HTTP.

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 dataUpgrade the VCE Vision Intelligent Operations plug-in to version 2.6.5 or later, and ensure all network communications use encrypted HTTPS/TLS to prevent credential interception.
