A command injection (missing input validation, escaping) in the ftp upgrade configuration interface on the Auerswald COMfort 1200 IP phone 3.4.4.1-10589 allows an authenticated remote attacker (simple user) -- in the same network as the device -- to trigger OS commands (like starting telnetd or opening a reverse shell) via a POST request to the web server.

Security readout for executives and security teams

Plain-English summary

This CVE affects the Auerswald COMfortel/COMfort 1200 IP phone firmware 3.4.4.1-10589. A low-privileged authenticated user on the same network could abuse the phone’s FTP upgrade configuration interface to run operating system commands on the device.

Executive priority

Treat this as a targeted network-device risk. Prioritize remediation if these phones are still deployed, especially where voice devices share networks with ordinary users or guests.

Technical view

The vulnerability is command injection caused by missing input validation or escaping in the FTP upgrade configuration interface. The CVE description limits the known affected scope to Auerswald COMfort 1200 IP phone version 3.4.4.1-10589 and requires authenticated network access.

Likely exposure

Exposure is likely limited to organizations that still operate this specific Auerswald IP phone firmware and allow users or attackers on the same network to reach its web configuration interface.

Exploitation context

The source bundle does not cite CISA KEV listing or active exploitation. The documented attack condition is authenticated remote access from the same network, with simple user privileges sufficient according to the CVE description.

Researcher notes

Evidence is narrow: one CVE record and vendor/advisory references identify command injection in one firmware version. No CVSS, CWE, patch version, or exploitation-in-the-wild evidence is present in the provided bundle.

Mitigation direction

  • Check Auerswald and Fraunhofer guidance for fixed firmware or retirement recommendations.
  • Restrict phone web management access to trusted administration networks only.
  • Remove unnecessary user accounts and enforce strong credentials.
  • Segment voice devices from general user and guest networks.
  • Monitor affected phones for unexpected configuration changes or reboots.

Validation and detection

  • Inventory Auerswald COMfortel/COMfort 1200 IP phones in use.
  • Confirm whether any device runs firmware 3.4.4.1-10589.
  • Verify the web configuration interface is not reachable from untrusted networks.
  • Review local accounts and privileges on affected devices.
  • Check vendor advisory status before declaring remediation complete.
