Ultrix DECnet-Internet gateway Vulnerability
When installing the DECnet-Internet gateway software it is necessary to create a guest account on the ULTRIX gateway host. By default, this account has /bin/csh as its shell. By virtue of the guest account having a valid shell, the DECnet-Internet gateway software can be exploited to allow unauthorized root access. Anyone using the DECnet-Internet gateway can gain unauthorized root privileges on the ULTRIX gateway host. |
