Rsh Server Detection |
||
Searches for the existence of rsh Detailed Explanation for this Vulnerability Assessment Summary : The rsh service is running. Description : The remote host is running the 'rsh' service. This service is dangerous in the sense that it is not ciphered - that is, everyone can sniff the data that passes between the rsh client and the rsh server. This includes logins and passwords. Also, it may permit poorly authenticated logins without passwords. If the host is vulnerable to TCP sequence number guessing (from any network) or IP spoofing (including ARP hijacking on a local network) then it may be possible to bypass authentication. Finally, rsh is an easy way to turn file-write access into full logins through the .rhosts or rhosts.equiv files. You should disable this service and use ssh instead. Solution : Comment out the 'rsh' line in /etc/inetd.conf Network Security Threat Level: Low / CVSS Base Score : 2 (AV:R/AC:H/Au:R/C:P/A:N/I:N/B:C) Networks Security ID: Vulnerability Assessment Copyright: This script is Copyright (C) 2005 Tenable Network Security |
