CVE-2017-6683
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 · uneditedA vulnerability in the esc_listener.py script of Cisco Elastic Services Controllers could allow an authenticated, remote attacker to execute arbitrary commands as the tomcat user on an affected system, aka an Authentication Request Processing Arbitrary Command Execution Vulnerability. More Information: CSCvc76642. Known Affected Releases: 2.2(9.76).
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 confidenceCommand injection vulnerability in the esc_listener.py script of Cisco Elastic Services Controller allows an authenticated remote attacker to execute arbitrary OS commands as the tomcat user. The vulnerability stems from improper sanitization of input during authentication request processing, enabling shell command execution through the script.

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 Elastic Services Controller installationSearch for Cisco ESC installation directories, services, or processes on the system. Look for process names containing 'esc' or 'tomcat' that may indicate Cisco ESC is running.Affected if Cisco Elastic Services Controller software is installed on the system
-
Verify installed version matches 2.2(9.76)Locate the Cisco ESC version information, typically found in the installation directory, version file, or via the escadm CLI tool if available. Compare the installed version string to 2.2(9.76).Affected if The installed version is exactly 2.2(9.76)
-
Locate esc_listener.py scriptSearch the filesystem for the esc_listener.py script, typically found within the Cisco ESC installation directory structure under scripts or bin folders.Affected if The esc_listener.py script exists on the system and is part of the Cisco ESC installation
-
Confirm management interface accessibilityCheck network listening ports and firewall rules to determine if the Cisco ESC management interface (typically ports 443, 8443, or similar) is exposed to network access. Review access control lists and network configurations.Affected if The Cisco ESC management interface is accessible from network segments beyond localhost or trusted admin networks
A system is affected if Cisco Elastic Services Controller version 2.2(9.76) is installed with the esc_listener.py component and its management interface is network-accessible to authenticated attackers.

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 Cisco vendor patch when available; if no patch exists, implement network access controls to restrict management interface exposure and consider disabling or replacing the vulnerable esc_listener.py component.
