CVE-2016-1443
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 virtual network stack on Cisco AMP Threat Grid Appliance devices before 2.1.1 allows remote attackers to bypass a sandbox protection mechanism, and consequently obtain sensitive interprocess information or modify interprocess data, via a crafted malware sample.
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 virtual network stack in Cisco AMP Threat Grid Appliance devices before version 2.1.1 contains a vulnerability that allows remote attackers to bypass the sandbox protection mechanism using crafted malware samples, enabling unauthorized access to sensitive interprocess information or modification of interprocess data.

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.
-
Confirm device is Cisco AMP Threat Grid ApplianceIdentify the appliance model through device inventory, network documentation, or by accessing the device's web interface or CLI and checking the system model informationAffected if The device is not a Cisco AMP Threat Grid Appliance, then this CVE does not apply
-
Check installed software versionAccess the appliance's administrative web interface or CLI and navigate to the system information or about section to view the installed firmware/software versionAffected if The installed version is any of the following: 1.0, 1.1, 1.2, 1.2.1, 1.3, 1.4, 1.4.1, 1.4.2, 1.4.3, 1.4.4, 1.4.5, or 1.4.6 - these versions contain the vulnerable virtual network stack
-
Verify virtual network stack is in useReview the appliance configuration to confirm that the virtual network stack feature is enabled for malware analysis or threat analysis workflowsAffected if The virtual network stack is enabled and the device runs a version between 1.0 and 1.4.6, the sandbox bypass vulnerability is present
A Cisco AMP Threat Grid Appliance is affected by this CVE if it runs software version 1.0 through 1.4.6 with the virtual network stack feature enabled.
