CVE-2017-9494
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 Comcast firmware on Motorola MX011ANM (firmware version MX011AN_2.9p6s1_PROD_sey) devices allows remote attackers to enable a Remote Web Inspector that is accessible from the public Internet.
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 Comcast firmware on Motorola MX011ANM devices (MX011AN_2.9p6s1_PROD_sey) contains a Remote Web Inspector feature that can be remotely enabled by attackers and accessed from the public Internet, allowing inspection of web traffic and potentially exposing sensitive 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.
-
Identify device modelLog into the device admin interface or check the device label to confirm it is a Motorola MX011ANM set-top boxAffected if Device model is not Motorola MX011ANM
-
Check firmware versionNavigate to the device settings or system information page in the web admin interface, or use the command line interface (CLI) if available, to determine the installed firmware versionAffected if Firmware version is exactly mx011an_2.9p6s1_prod_sey
-
Locate Remote Web Inspector configurationSearch the device web interface for settings related to 'Remote Web Inspector', 'Web Inspector', 'Remote Debugging', or similar diagnostic features; check under advanced settings or maintenance sectionsAffected if Remote Web Inspector feature is present and configurable on the device
-
Verify if Remote Web Inspector is enabledExamine the configuration status of the Remote Web Inspector feature to determine if it is currently turned on or accessibleAffected if Remote Web Inspector is enabled or accessible on the device
-
Check network exposure of inspector portPerform a port scan on the device from an external network location, commonly targeting ports 8080, 8888, or 9999 used by web inspector services, to determine if the interface is reachable from the public InternetAffected if The Remote Web Inspector port is exposed and reachable from the public Internet
A user is affected if they have a Motorola MX011ANM device running firmware version mx011an_2.9p6s1_prod_sey with the Remote Web Inspector feature enabled and exposed to the public Internet.

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 dataRestrict network access to device management interfaces via firewall rules or network segmentation; contact Comcast for firmware updates to disable or secure the Remote Web Inspector feature.
