WORKAROUND: Change the set-community-name and use the Access Control List as described in "HP JetDirect Print Servers - Making HP JetDirect Print Servers Secure on the Network": http://www.hp.com/cposupport/networking/support_doc/ bpj05999.html#P88_10129 LIMITING THE VULNERABILITY SNMPv1 security relies on the set community name. It is important that a set-community-name be configured on the JetDirect device and that it be kept secret. JetDirect Print Servers offer an Access Control List that can be used to specify which hosts can make SNMP configuration changes to JetDirect Print Servers. The steps above can help prevent exploitation of the vulnerability. To eliminate the vulnerability before a fix is available SNMP can be disabled on the JetDirect device. DISABLING SNMP ON A JETDIRECT PRINT SERVER 1. Update the firmware to the highest level as described in the JetDirect Upgrade Instructions document: http://www.hp.com/cposupport/networking/support_doc/bpj06917.html NOTE: Disabling SNMP may affect device discovery and port monitors that use SNMP to get status on the device. Use this feature with care. 2. Telnet to the JetDirect device (on the latest firmware) and type: snmp-config: 0 quit This will completely disable SNMP on the JetDirect device. HP always recommends upgrading JetDirect firmware for the latest bug fixes and security benefits. The upgrade firmware and download utility are available free of charge: http://www.hp.com/cposupport/networking/support_doc/bpj06917.html The following is a list of JetDirect Product Numbers that can be freely upgraded to X.08.32 or X.21.00 or higher firmware. The latest firmware revision available for download is given. For example, the latest firmware revision for the J3110A is G.08.32. EIO (Peripherals LaserJet 4000, 5000, 8000, etc...)

The HP OC SS7 (OpenCall) products J3362A and J5938A running on HP-UX releases 10.20 and 11.X are not vulnerable if the applicable HP-UX patch listed above is installed. ============================================================ NOTE: The patches are labeled OV (OpenView). However, the patches are also applicable to systems that are _NOT_ running OpenView. ============================================================ Workaround for HP-UX Systems: If a patch is not available for your platform or you cannot install an available patch, snmpd and snmpdm can be disabled by removing their entries from /etc/services and removing the execute permissions from /usr/sbin/snmpd and /usr/sbin/snmpdm.
