VAR-200612-0590
Vulnerability from variot - Updated: 2025-04-10 23:01PhoneCtrl.exe in Linksys WIP 330 Wireless-G IP Phone 1.00.06A allows remote attackers to cause a denial of service (crash) via a TCP SYN scan, as demonstrated using TCP ports 1-65535 with nmap. Linksys WIP330 'PhoneCtrl.exe' is prone to a denial-of-service vulnerability when the device is full port-range scanning. Exploiting this issue allows remote attackers to crash and reboot affected devices, denying service to legitimate users. Linksys WIP330 firmware version 1.00.06a is affected by this issue; other versions may also be affected. Linksys WIP 330 is a VoIP network cordless phone. If I run a port-wide Nmap scan of the WIP 330's IP address with the command: nmap -P0 -p 1-65535 then PhoneCtrl.exe will crash at the end of the Nmap scan.
