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 · unedited
A vulnerability has been identified in InterMesh 7177 Hybrid 2.0 Subscriber (All versions < V8.2.12), InterMesh 7707 Fire Subscriber (All versions < V7.2.12 only if the IP interface is enabled (which is not the default configuration)). The web server of affected devices does not authenticate GET requests that execute specific commands (such as `ping`) on operating system level.

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 confidence

This is an unauthenticated command injection vulnerability in the web server of InterMesh 7177 Hybrid 2.0 Subscriber (versions < V8.2.12) and 7707 Fire Subscriber (versions < V7.2.12 with IP interface enabled). Attackers can send unauthenticated GET requests that execute OS-level commands such as ping directly on the device without any authentication.

MitigationUpgrade InterMesh 7177 Hybrid devices to V8.2.12 or later, and 7707 Fire devices to V7.2.12 or later. For 7707 Fire devices, keep the IP interface disabled unless explicitly required, as it is not enabled by default.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the InterMesh device model
    Access the device web interface or check the physical device label. Look for the model number 7177 Hybrid 2.0 Subscriber or 7707 Fire Subscriber.
    Affected if The device is a Siemens Intermesh 7177 Hybrid 2.0 Subscriber or 7707 Fire Subscriber.
  2. Check the installed firmware version
    Log into the device web interface and navigate to the Status or System Information page to view the firmware version. Alternatively, check via CLI if available.
    Affected if The firmware version is below 8.2.12 for the 7177 Hybrid 2.0, or below 7.2.12 for the 7707 Fire Subscriber.
  3. For 7707 Fire: verify if IP interface is enabled
    In the device web interface, go to Network or Interface settings and check whether the IP interface is turned on. This is not enabled by default.
    Affected if The device is a 7707 Fire Subscriber with IP interface enabled, and firmware is below 7.2.12.
  4. Confirm web server is network accessible
    Check if the device web server (HTTP/HTTPS on port 80/443 or custom ports) is reachable from network segments accessible to potential attackers.
    Affected if The web interface is exposed to untrusted networks without firewall restrictions.

You are affected if you have an InterMesh 7177 Hybrid 2.0 Subscriber with firmware below 8.2.12, or a 7707 Fire Subscriber with firmware below 7.2.12 and the IP interface enabled.

Upgrade available Upgrade to 7.2.12 / 8.2.12 or later
Fixed in 7.2.128.2.12
Interim mitigation

Upgrade InterMesh 7177 Hybrid devices to V8.2.12 or later, and 7707 Fire devices to V7.2.12 or later. For 7707 Fire devices, keep the IP interface disabled unless explicitly required, as it is not enabled by default.

Recommended fix High confidence

Intermesh 7177 Hybrid 2.0 Subscriber: upgrade to V8.2.12 | Intermesh 7707 Fire Subscriber: upgrade to V7.2.12

  1. 1. Identify the specific Intermesh device model (7177 Hybrid 2.0 Subscriber or 7707 Fire Subscriber)
  2. 2. Check the current firmware version of the device
  3. 3. For Intermesh 7707 Fire Subscriber: Verify whether the IP interface is enabled (if disabled, this vulnerability does not apply as it is not the default configuration)
  4. 4. Obtain the firmware upgrade from official Siemens/cert-portal sources: V8.2.12 for 7177 Hybrid 2.0 Subscriber, V7.2.12 for 7707 Fire Subscriber
  5. 5. Apply the firmware upgrade following the vendor's documented upgrade procedure
  6. 6. After upgrade, verify the web server now properly authenticates GET requests before executing OS-level commands
Caveat Review vendor release notes for any configuration changes or compatibility considerations between current and new firmware versions
