Arescom » Netdsl : Security Vulnerabilities, CVEs,

The telnet port in Arescom NetDSL 1000 router allows remote attackers to cause a denial of service via a series of connections with long strings, which causes a large number of login failures and causes the telnet service to stop.

The default configuration of Arescom NetDSL 800 does not require authentication, which allows remote attackers to cause a denial of service or reconfigure the router.
