Title: ElectroSoft ElectroComm Denial of Service Vulnerability
Severity: MODERATE
Description:
ElectroComm is a telnet-comm port server for Windows 9x/NT, allowing users to connect a PC's comm port to a TCP/IP network and login remotely using Telnet.
The ElectroComm Telnet service listens for incoming connection on TCP port 23.
An attacker can execute a denial of service attack on the ElectroComm service by submitting two groups of approximately 160,000 characters to the target's telnet port.
This increases CPU utilization to 100%, and crashes the ElectroComm service, which reports 'Run-time error 381' / 'Invalid array index.'
Affected Products:
- ElectroSoft ElectroComm 1.0.0
- ElectroSoft ElectroComm 2.0.0
