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
Advantage Century Telecommunication (ACT) P202S IP Phone 1.01.21 running firmware 1.1.21 has multiple undocumented ports available, which (1) might allow remote attackers to obtain sensitive information, such as memory contents and internal operating-system data, by directly accessing the VxWorks WDB remote debugging ONCRPC (aka wdbrpc) on UDP 17185, (2) reflect network data using echo (TCP 7), or (3) gain access without authentication using rlogin (TCP 513).

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 ACT P202S IP Phone firmware 1.1.21 contains multiple undocumented services exposing sensitive data: VxWorks WDB remote debugging (UDP 17185) allows memory/OS extraction, echo service (TCP 7) enables network data reflection, and rlogin (TCP 513) provides unauthenticated access. These debugging and legacy services should never be exposed on production networks.

MitigationDisable or block access to UDP port 17185, TCP port 7, and TCP port 513 at the network perimeter; if available, apply vendor firmware updates to remove these undocumented services.

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
    Access the device web interface, admin panel, or check physical labeling to confirm the device is an ACT P202S IP Phone from Advantage Century Telecommunication
    Affected if The device model is ACT P202S or P202s from Advantage Century Telecommunication
  2. Check the installed firmware version
    Access the device admin interface, web UI, or use SNMP to query the firmware version. Compare against the affected version 1.1.21
    Affected if Firmware version is exactly 1.1.21 (1.01.21_firmware_1.1.21)
  3. Scan for open UDP port 17185
    Use a network port scanner (such as nmap) to probe the device for UDP port 17185: nmap -sU -p 17185 <device_ip>
    Affected if UDP port 17185 is open and responding, indicating VxWorks WDB debugging service is exposed
  4. Scan for open TCP port 7
    Use a network port scanner to probe the device for TCP port 7: nmap -p 7 <device_ip>
    Affected if TCP port 7 is open, indicating the echo service is enabled and accessible
  5. Scan for open TCP port 513
    Use a network port scanner to probe the device for TCP port 513: nmap -p 513 <device_ip>
    Affected if TCP port 513 is open, indicating the rlogin service is enabled and accessible

The device is affected if it is an ACT P202S IP Phone running firmware version 1.1.21 AND any of UDP port 17185, TCP port 7, or TCP port 513 are exposed on the network.

Mitigation

Disable or block access to UDP port 17185, TCP port 7, and TCP port 513 at the network perimeter; if available, apply vendor firmware updates to remove these undocumented services.
