CVE-1999-0189

Summary

CVE-1999-0189 is a vulnerability affecting Solaris systems where the rpcbind service listens on a high numbered UDP port, which may not be filtered by default firewalls. Since the standard port number for rpcbind is 111, unsecured access to this high port could allow remote attackers to execute arbitrary commands on the system. This issue poses a significant risk, as it enables unauthenticated and unencrypted connections, making it essential for administrators to configure their firewalls to block access to these high ports or limit access to trusted sources.
