CVE-2016-2352
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 Accellion File Transfer Appliance (FTA) before FTA_9_12_40 allows remote authenticated users to execute arbitrary commands by leveraging the YUM_CLIENT restricted-user role.
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 Accellion File Transfer Appliance (FTA) before version FTA_9_12_40 contains a vulnerability in the YUM update mechanism where the YUM_CLIENT restricted-user role can be leveraged to execute arbitrary commands on the underlying operating system. This allows authenticated users with limited privileges to escalate to full system command execution.

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 Accellion FTA versionAccess the FTA admin interface or check system files to determine the currently installed version numberAffected if Installed version is FTA_9_11_210 or earlier (any version before FTA_9_12_40)
-
Check YUM_CLIENT role assignmentsReview user role configurations in the FTA administrative panel to see which accounts have the YUM_CLIENT restricted-user role assignedAffected if The YUM_CLIENT role is assigned to any user account, regardless of privilege level
-
Verify YUM update mechanism accessibilityExamine the YUM update system configuration to determine if the YUM_CLIENT role permits access to the update functionalityAffected if Users with YUM_CLIENT role can access or invoke the YUM update mechanism
The environment is affected if the Accellion FTA version is 9_11_210 or earlier and the YUM_CLIENT role is enabled for any authenticated user, allowing privilege escalation through the YUM update system.

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 Accellion FTA to version FTA_9_12_40 or later to remediate this vulnerability. Until the upgrade is completed, restrict or monitor YUM_CLIENT role assignments closely.
