CVE-2017-6634
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 Device Manager web interface of Cisco Industrial Ethernet 1000 Series Switches 1.3 could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack against a user of an affected system. The vulnerability is due to insufficient CSRF protection by the Device Manager web interface. An attacker could exploit this vulnerability by persuading a user of the interface to follow a malicious link or visit an attacker-controlled website. A successful exploit could allow the attacker to submit arbitrary requests to an affected device via the Device Manager web interface and with the privileges of the user. Cisco Bug IDs: CSCvc88811.
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 confidenceA CSRF vulnerability in the Device Manager web interface of Cisco Industrial Ethernet 1000 Series Switches allows unauthenticated remote attackers to trick authenticated users into submitting arbitrary requests. The web interface lacks proper anti-CSRF tokens or validation, enabling attackers to perform actions with the privileges of the victim user.

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 model is Cisco Industrial Ethernet 1000 SeriesAccess the device console or web interface and identify the exact model number. For CLI: run 'show version' or 'show hardware' and look for 'Industrial Ethernet 1000' in the product name.Affected if The device is not a Cisco Industrial Ethernet 1000 Series Switch - this CVE only applies to that product line.
-
Check firmware version is 1.3_baseVia CLI: run 'show version' and examine the firmware/IOS version string. Via web interface: check the Device Manager system information page. Look for a version string exactly matching '1.3_base'.Affected if The firmware version is anything other than 1.3_base, or if you cannot determine the version - only version 1.3_base is listed as affected.
-
Verify Device Manager web interface is enabledVia CLI: run 'show ip http server' or 'show running-config | include http' to check if the HTTP/HTTPS web interface is active. Alternatively, attempt to access http://<device-ip> or https://<device-ip> from a browser.Affected if The Device Manager web interface is disabled or not accessible - the CSRF vulnerability exists in the web interface code, so it only matters if the interface is running.
-
Confirm web interface lacks anti-CSRF protectionExamine login and form submission pages in the Device Manager web interface. Check HTML forms for hidden token fields (look for input type='hidden' with name containing 'csrf', 'token', or 'nonce'). Also check cookies for CSRF-related attributes.Affected if No anti-CSRF tokens or SameSite cookie attributes are present in the web interface - this is the core vulnerability condition.
You are affected if you have a Cisco Industrial Ethernet 1000 Series Switch running firmware version 1.3_base with the Device Manager web interface enabled, and the web interface lacks anti-CSRF token validation in its forms.

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 the vendor patch from Cisco that addresses CSCvc88811. As a workaround, instruct users to avoid clicking untrusted links and to log out of the Device Manager when not in use.
