Description
If login by the user "nobody" is allowed for secure RPC, there is an increased risk of system compromise. If keyserv holds a private key for the "nobody" user, it will be used by key_encryptsession to compute a magic phrase which can be easily recovered by a malicious user.
ℹ️ Check
Determine if the rpc-authdes package is installed: # pkg list solaris/legacy/security/rpc-authdes If the output of this command is: pkg list: no packages matching 'solaris/legacy/security/rpc-authdes' installed no further action is required. Determine if "nobody" access for keyserv is enabled. # grep "^ENABLE_NOBODY_KEYS=" /etc/default/keyserv If the output of the command is not: ENABLE_NOBODY_KEYS=NO this is a finding.
✔️ Fix
Determine if the rpc-authdes package is installed: # pkg list solaris/legacy/security/rpc-authdes If the output of this command is: pkg list: no packages matching 'solaris/legacy/security/rpc-authdes' installed no further action is required. The root role is required. Modify the /etc/default/keyserv file. # pfedit /etc/default/keyserv Locate the line: #ENABLE_NOBODY_KEYS=YES Change it to: ENABLE_NOBODY_KEYS=NO
