-----BEGIN PGP SIGNED MESSAGE----- ============================================================================== Security Advisory CERT-NL ============================================================================== Author/Source : Xander Jansen Index : S-98-75 Distribution : World Page : 1 Classification: External Version: 1 Subject : HPOpenview: SNMP community string Date : 03-dec-98 ============================================================================== By courtesy of HEWLETT-PACKARD we received information on a security vulnerability with certain HP Openview SNMP agents which may reduce the managebility of affected systems (see also S-98-74 for a similar advisory for Sun Solstice products). CERT-NL recommends users of these agents to follow the instructions and install the available patches as mentioned below. - ------------------------------------------------------------------------- HEWLETT-PACKARD COMPANY SECURITY BULLETIN: #00088, 30 November 1998 - ------------------------------------------------------------------------- The information in the following Security Bulletin should be acted upon as soon as possible. Hewlett-Packard Company will not be liable for any consequences to any customer resulting from customer's failure to fully implement instructions in this Security Bulletin as soon as possible. - ------------------------------------------------------------------------- PROBLEM: A SNMP community string in HP OpenView allow access to certain SNMP variables. PLATFORM: HP 9000 series 700/800. DAMAGE: May reduce manageability of affected HP-UX systems. SOLUTION: Install the patches listed below. AVAILABILITY: All patches are available now. - ------------------------------------------------------------------------- I. A. Background Reference: ISS X-force SNMP community resource notice, dated November 2nd, 1998. A SNMP community string exists in HP OpenView SNMP agent implementations allowing access to certain SNMP variables. This may result in limited manageability of affected HP-UX systems. The system remains operational but will be unable to respond to some queries from a management server. This problem is not an OpenView-specific problem, but OpenView can be affected when communicating with systems that have an affected agent. This HP OpenView Emanate SNMP Agent has two revisions currently supported, release 2.X and 14.X. HP recommends upgrading to the 14.X release and applying the patch to circumvent this vulnerability. B. Fixing the problem The defect is now fixed such that an unauthorized user can not use this mechanism. Please install the applicable patch: Emanate 14.2 version on HP-UX revision 11.00: PHSS_16846 Emanate 14.2 version on HP-UX revision 10.20: PHSS_16845 Emanate 14.0 version on HP-UX revision 10.0X, 10.10: PHSS_16800 Emanate 14.0 version on HP-UX revision 9.X: PHSS_16799 Solaris 2.3 and 2.4 OpenView Emanate14.0 agent: PSOV_02190 Solaris 2.5.1 and 2.6 OpenView Emanate14.2 agent: PSOV_02191 The Solaris agent patches are available from: http://ovweb.external.hp.com:80/cpe/patches/emanate/14.x/sparc_2.X.html CAUTION: Installing any earlier HP OV Emanate patch, or reinstalling HP OpenView Network Node Manager (NNM) will reverse the protective effect of the patches listed above. Reinstallation of the above referenced patch will then be necessary. This means that if a system administrator deinstalls one of the earlier patches after installing the security patch, they will overwrite the security fixes with older software. The Solaris, HP-UX 9.X, and HP-UX 10.X patches are _NOT_ cumulative. The HP-UX 11.X patch is, however, cumulative (one that supersedes), and will not be affected in this manner. C.
