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
UTStarcom F1000 VOIP WIFI Phone s2.0 running VxWorks 5.5.1 with kernel WIND 2.6 does not allow users to disable access to (1) SNMP or (2) the rlogin port TCP 513, which allows remote attackers to exploit other vulnerabilities such as CVE-2005-3716, or execute arbitrary shell commands via rlogin, which does not require authentication.

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

The UTStarcom F1000 VOIP WiFi phone running VxWorks 5.5.1 contains a design flaw where users cannot disable the SNMP service or rlogin service on TCP port 513. The rlogin service accepts connections without authentication, allowing remote attackers to execute arbitrary shell commands on the device.

MitigationSince the device does not support disabling these services, network segmentation should be used to isolate the device and block external access to SNMP and rlogin ports. If the device is end-of-life, replacement with a current model that supports service configuration should be considered.

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 device model
    Locate the physical device or check network inventory for UTStarcom F1000 VOIP WiFi Phone. Confirm the model number matches F1000.
    Affected if The device is a UTStarcom F1000 VOIP WiFi Phone.
  2. Check the firmware version
    Access the device admin interface or check the device documentation to determine the installed firmware version. Compare against version 2.0.
    Affected if The firmware version is exactly 2.0.
  3. Verify rlogin service is exposed
    Perform a TCP port scan against the device on port 513 (rlogin) using tools like nmap or netcat. Check if the port responds to connection attempts.
    Affected if TCP port 513 is open and accepting connections on the device.
  4. Check network accessibility of rlogin
    Determine if the device IP address is reachable from network segments that should not have access to internal management services. Attempt a test connection to port 513 from an unauthorized segment if permitted by policy.
    Affected if The rlogin service (port 513) is accessible from network segments outside the trusted management network.

You are affected if you have a UTStarcom F1000 VOIP WiFi Phone running firmware version 2.0 with TCP port 513 (rlogin) accessible on your network.
