Rule: -- Sid: 1915 -- Summary: This event is generated when an attempt is made to exploit a format string vulnerability associated with the Remote Procedure Call (RPC) rpc.statd. -- Impact: Remote root access. This allow may permit execution of arbitrary commands with the privileges of root. -- Detailed Information: The rpc.statd daemon is a component of Network File System (NFS) that implements the Network Status and Monitor (NSM) RPC functions. NSM monitors the status of NFS clients and servers and maintains a list of hosts that have registered to be notified when an NFS host crashes. There is a format string vulnerability associated with the code that implements the monitoring of a given host, possibly permitting the execution of arbitrary commands with the privileges of root. -- Affected Systems: Conectiva Linux 4.0, 4.1, 4.2, 5.0, 5.1 Debian Linux 2.2, 2.3 Red Hat Linux 6.0, 6.1, 6.2 SuSE Linux 6.3, 6.4, 7.0 Trustix Secure Linux 1.0, 1.1 -- Attack Scenarios: An attacker can attempt to exploit the format string error allowing execution of arbitrary commands with the privileges of root. -- Ease of Attack: Simple. Exploit code is freely available. -- False Positives: None Known. -- False Negatives: None Known. -- Corrective Action: Limit remote access to RPC services. Filter RPC ports at the firewall to ensure access is denied to RPC-enabled machines. Disable unneeded RPC services. -- Contributors: Original rule written by Brian Caswell <bmc@sourcefire.com> Sourcefire Research Team Judy Novak <judy.novak@sourcefire.com> -- Additional References: CVE http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2000-0666 Bugtraq http://www.securityfocus.com/bid/1480 --
