CVE-1999-1527: High severity Sun Forte vulnerability
Internal HTTP server in Sun Netbeans Java IDE in Netbeans Developer 3.0 Beta and Forte Community Edition 1.0 Beta does not properly restrict access to IP addresses as specified in its configuration, which allows arbitrary remote attackers to access the server.
Affected Software
Remediation
Recommended actions to resolve this vulnerability, in priority order.
- Configuration
Configure the IDE's internal HTTP server to bind to localhost (127.0.0.1) or to only allow connections from specific trusted IP addresses. If the built-in IP restriction mechanism cannot be relied upon, disable the internal HTTP server.
Internal HTTP server (Apache NetBeans / Sun Forte) IP address access control / bind address = bind to localhost or restrict to specific trusted IP ranges - Compensating control
Block access to the IDE's internal HTTP server at the host and network perimeter (host firewall, network ACLs, or firewall) so that only trusted management IPs or localhost can reach the service; deny all other external access.
- Operational
If the internal HTTP server was reachable from untrusted networks, review access logs for unauthorized activity, rotate any credentials or tokens that may have been exposed, and monitor vendor advisories to apply any vendor-supplied fixes when they become available.
