PROTOCOL-SERVICES -- Snort has detected traffic that may indicate the presence of the rservices protocol or vulnerabilities in the rservices protocols on the network.
PROTOCOL-SERVICES rsh root
This event is generated when an attempt to login as the superuser is attempted using rsh.
Serious. If successful the attacker may have gained superuser access to the host.
This rule generates an event when a connection is made using "rsh" with the username "root". Such activity is indicative of attempts to abuse insecure machines with a known default configuration.
Some UNIX systems use the "rsh" daemon which permits remote "root" logins. This may allow an attacker to connect to the machine and establish an interactive session.
Ease of Attack:
Simple, no exploit software required
What To Look For
No public information
Known false positives, with the described conditions
A system administrator may be logging in to a host using the username "root"
