CVE-2014-8417
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 · uneditedConfBridge in Asterisk 11.x before 11.14.1, 12.x before 12.7.1, and 13.x before 13.0.1 and Certified Asterisk 11.6 before 11.6-cert8 allows remote authenticated users to (1) gain privileges via vectors related to an external protocol to the CONFBRIDGE dialplan function or (2) execute arbitrary system commands via a crafted ConfbridgeStartRecord AMI action.
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.

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 installed Asterisk versionRun 'asterisk -V' or 'asterisk --version' to display the installed version. Alternatively, check /usr/lib/asterisk/modules/ for the asterisk binary and use 'rpm -q asterisk' or 'dpkg -l asterisk' depending on your package manager.Affected if The version falls within 11.0.0 to 11.14.0, 12.0.0 to 12.7.0, or 13.0.0, or is Certified Asterisk 11.6 any build.
-
Confirm ConfBridge module is loadedRun 'module show like confbridge' in the Asterisk CLI (asterisk -r) to check if the ConfBridge application module is loaded.Affected if ConfBridge module is loaded and the version is within the affected ranges.
-
Verify AMI is enabled and accessibleCheck /etc/asterisk/manager.conf (or /etc/asterisk/manager.conf.d/) for enabled = yes under [general] and review any [user] sections for read/write permissions. Also check if the AMI port (default 5038) is listening with 'netstat -tlnp | grep 5038' or 'ss -tlnp | grep 5038'.Affected if AMI is enabled and accessible on the network, allowing authenticated users to send commands.
-
Check for ConfBridge recording configurationExamine /etc/asterisk/confbridge.conf and any included configuration files for the 'record_file' parameter under dialplan bridges or user profiles, or check for ConfBridge dialplan applications that enable recording.Affected if ConfBridge recording is configured and the version is affected.
If the installed Asterisk version is within the vulnerable ranges AND ConfBridge is loaded AND AMI access is available to authenticated users, the environment is affected by this privilege escalation vulnerability.

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 data11.14.112.7.113.0.1
Upgrade Asterisk to version 11.14.1, 12.7.1, 13.0.1, or 11.6-cert8 or later. Review and restrict AMI access permissions, as this vulnerability requires authenticated AMI access.
