Title: NetcPlus SmartServer3 DoS Vulnerability
Severity: MODERATE
Description:
SmartServer3 is an email server designed for small networks.
The POP3 and SMTP services within SmartServer3 are prone to a denial-of-service issue. Submitting an unusually long argument to the User or Pass command in the POP3 service will cause the server to stop responding and refuse any new connections. An unusually long argument submitted to the SMTP service after the 'HELO' command will cause the server to stop responding, yet will still accept new connections. In either instance, a restart of the server is required to gain normal functionality.
Successful exploits could allow attackers to execute arbitrary commands, but this has not been confirmed.
Affected Products:
- NetcPlus SmartServer3 3.75.0
