CVE-2014-3399
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 SSL VPN implementation in Cisco Adaptive Security Appliance (ASA) Software 9.2(.2.4) and earlier does not properly manage session information during creation of a SharePoint handler, which allows remote authenticated users to overwrite arbitrary RAMFS cache files or inject Lua programs, and consequently cause a denial of service (portal outage or system reload), via crafted HTTP requests, aka Bug ID CSCup54208.

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 Cisco ASA Software versionLog into the ASA CLI and run 'show version' or use ASDM to view the system software versionAffected if The installed version is 9.2(x) where x is 2.4 or lower, or any version in the 9.2 branch <= 9.2(2.4)
-
Verify SSL VPN is enabledCheck ASA configuration for any VPN-related settings using 'show running-config | include vpn' or via ASDM under Configuration > Remote Access VPNAffected if Any SSL VPN (clientless or AnyConnect) is active on the device
-
Confirm SharePoint handler is configuredExamine the SSL VPN portal configuration for SharePoint integration using 'show running-config webvpn' or check for sharepoint-related settings in the VPN portal profileAffected if SharePoint handler or any SharePoint-related webvpn features are configured on the SSL VPN portal
-
Inspect for unauthorized Lua scripts or cache anomaliesUse 'show file' commands or access the ASA file system via ' privileged exec mode to check for unexpected Lua program files in the cache or RAMFS storage areasAffected if Unexpected Lua scripts exist in the VPN cache or unusual modifications to RAMFS cache files are found
You are affected if your Cisco ASA runs version 9.2(2.4) or earlier AND has SSL VPN with SharePoint handler enabled, as the vulnerability requires the SSL VPN SharePoint feature to be configured.
Generated from the published advisory. Verify against your own configuration.
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 Cisco ASA Software to a version beyond 9.2(.2.4) that addresses CVE-2014-3399; given this is a session management flaw in the SSL VPN, ensure only authorized users have VPN access and monitor for anomalous HTTP requests to the SharePoint handler.
