S-319: Cisco Intrusion Prevention System Vulnerability
Cisco Intrusion Prevention System (IPS) platforms that have gigabit network interfaces installed and are deployed in inline mode contain a denial of service vulenrability in the handling of jumbo Ethernet frames. This vulnerability may lead to a kernel panic that requires a power cycle to recover platform operaiton. The risk is MEDIUM. Successful exploitation of the vulnerability may result in a network denial of service condition. A power cycle is required to recover operations. An attacker may be able to evade access controls and detection of malicious activity int he case of Cisco IPS 4260-4270 platforms that have hardware bypass configured to pass traffic in the event of a kernel panic.

NAME

       SNMP::Info::Layer2::Airespace - SNMP Interface to Cisco (Airespace) Wireless Controllers

AUTHOR

       Eric Miller

SYNOPSIS

	   #Let SNMP::Info determine the correct subclass for you.

	   my $airespace = new SNMP::Info(
				 AutoSpecify => 1,
				 Debug	     => 1,
				 DestHost    => 'myswitch',
				 Community   => 'public',
				 Version     => 2
			       )

	   or die "Can't connect to DestHost.
";

	   my $class = $airespace->class();
	   print " Using device sub class : $class
";

DESCRIPTION

       Provides abstraction to the configuration information obtainable from Cisco (Airespace) Wireless Controllers through SNMP.

       For speed or debugging purposes you can call the subclass directly, but not after determining a more specific class using the method above.

       my $airespace = new SNMP::Info::Layer2::Airespace(...);
