ACT P202S VoIP phone multiple undocumented default ports and services

act-p202s-default-port (24149) The risk level is classified as HighHigh Risk


ACT (Advantage Century Telecommunication Corporation) P202S could allow a remote attacker to gain unauthorized access to the device using one of several undocumented open ports. TCP port 7, TCP port 512, and UDP port 17185 are open by default and provides access to the echo, rlogin, and VxWorks WDB remote debug service (wdbrpc). In addition, the device has a hard coded NTP service that is enabled by default. An attacker could connect to one of these ports or use the NTP service to view or modify device configuration information, reset the device to the factory default settings, write to the registry, dump memory, and perform other malicious activity.
