CVE-2012-2285
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 · uneditedEMC Cloud Tiering Appliance (aka CTA, formerly FMA) 9.0 and earlier, and Cloud Tiering Appliance Virtual Edition (CTA/VE) 9.0 and earlier, allows remote attackers to obtain GUI administrative access by sending a crafted file during the authentication phase.
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 confidenceThe vulnerability is an authentication bypass in EMC Cloud Tiering Appliance versions 9.0 and earlier. Remote attackers can gain administrative GUI access by sending a specially crafted file during the authentication phase, circumventing normal login controls.

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.
-
Determine the installed CTA versionAccess the appliance's administrative GUI or CLI and locate the version information, typically found in the About or System Information sectionAffected if The version is 9.0 or any version lower than 9.0
-
Identify network exposure of management interfaceDetermine whether the CTA management GUI (typically ports 443 or 8080) is accessible from untrusted or external networks by reviewing firewall rules, network configurations, or ACLsAffected if The administrative interface is reachable from networks outside the trusted internal environment
-
Review authentication configuration filesInspect the CTA configuration directory for any unexpected or newly created authentication-related files, particularly in the web server or authentication module directoriesAffected if Unexpected files exist in authentication-related directories that were not part of a known baseline
-
Examine authentication logs for anomaliesReview the CTA system and authentication logs for unusual login patterns, failed authentication attempts, or successful logins from unexpected sources during the authentication phaseAffected if Logs show successful administrative logins without corresponding proper credential submission or logins from untrusted sources
A user is affected if the CTA version is 9.0 or earlier AND the management interface is accessible from untrusted networks, allowing remote attackers to send specially crafted authentication files.

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 to a patched version of CTA (9.0+). If immediate patching is not possible, restrict network access to the appliance's management interface using firewalls or ACLs to limit exposure to untrusted networks.
