Hidden SNMP community in HP OpenView
Synopsis:
Internet Security Systems (ISS) X-Force has researched a hidden SNMP community
string that exists in HP OpenView. This community may allow unauthorized
access to certain SNMP variables. Attackers may use this hidden community to
learn about network topology as well as modify MIB variables.
Affected Versions:
ISS X-Force has confirmed that this vulnerability is present in HP OpenView
Version 5.02. Earlier versions are believed to be vulnerable. HP-UX 9.X and
HP-UX 10.X SNMP agents are vulnerable if OpenView is installed. OpenView for
Solaris 2.X is also vulnerable. OpenView for Windows NT is not vulnerable.
Fix Information:
HP has made the following patches available:
PHSS_16800: HP-UX Version 10.X
PHSS_16799: HP-UX Version 9.X
PHOV_02190: Solaris Version 2.X
Description:
All hosts in a managed network rely on the proper delivery and collection of
SNMP data. This vulnerability allows remote attackers access to portions of
the MIB tree used for configuration and maintenance of the SNMP agent.
Attackers may use this hidden community from remote to gain information
otherwise reserved for authorized users. Attackers can also use this community
to disrupt collection of data over SNMP as well as sever communication between
Collection Agents and Management stations.
Additional Information:
ISS Internet Scanner and ISS RealSecure real-time intrusion detection software
have the capability to detect these vulnerabilities.
