CVE-2014-0899
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 · uneditedftpd in IBM AIX 7.1.1 before SP10 and 7.1.2 before SP5, when a Workload Partition (aka WPAR) for AIX 5.2 or 5.3 is used, allows remote authenticated users to bypass intended permission settings and modify arbitrary files via FTP commands.
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 ftpd daemon in IBM AIX 7.1.1 before SP10 and 7.1.2 before SP5 contains an authorization bypass flaw when Workload Partitions (WPARs) configured for AIX 5.2 or 5.3 are in use. Authenticated remote FTP users can bypass intended file permission restrictions and write to arbitrary files on the system.

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 AIX version and service pack levelRun 'oslevel -s' to get the full version and service pack level, or 'oslevel' to get the base versionAffected if Version shows 7.1.1 without SP10 or later, or 7.1.2 without SP5 or later
-
Verify ftpd daemon is runningRun 'lssrc -s ftpd' or 'ps -ef | grep ftpd' to check if the FTP daemon is activeAffected if ftpd process is shown as active in the subsystem list or running processes
-
Check for WPARs configured with AIX 5.2 or 5.3 compatibilityRun 'lswpar -a' to list all Workload Partitions and examine the 'OS' or 'Version' field for each WPARAffected if Any WPAR shows OS type AIX 5.2 or AIX 5.3, indicating WPARs are configured for those legacy versions
-
Confirm FTP service is accessible remotelyVerify that the FTP port (21) is listening by running 'netstat -an | grep :21' or 'ftp localhost' to test connectivityAffected if Port 21 is in LISTEN state and FTP access is permitted from network
A system is affected if it runs IBM AIX 7.1.1 before SP10 or 7.1.2 before SP5, has ftpd enabled, and has WPARs configured for AIX 5.2 or 5.3 compatibility.

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 dataApply IBM AIX service pack SP10 for version 7.1.1 or SP5 for version 7.1.2 to address the ftpd authorization bypass. Consider disabling anonymous FTP and restricting FTP access to only essential personnel until the patch is applied.
