Cross-Ref: ISS Security Advisory: Hidden community string in SNMP
implementation

________________________________________________________________________________
1. Background
Solstice Enterprise Agents(tm) expands the scope of enterprise management
by providing a comprehensive development and runtime environment
enabling the creation of custom, extensible agents for device and
system management for the Solaris(tm) operating environment. Solstice
Enterprise Agents(SEA) supports both the Simple Network Management
Protocol and DMI protocols.
Simple Network Management Protocol(SNMP) was designed to allow the
remote management of systems and devices on a network. SNMP relies on
processes known as master agents and subagents. Upon invocation,
agents read various configuration files and maintain Management
Information Bases(MIBs). Access to information in the MIBs can be
controlled by community strings. A default community string is present
in the Sun SNMP subagent that may be exploited by remote attackers to
modify system parameters or execute arbitrary commands with root
privileges.
SEA was initially available as an unbundled product and later bundled
with Solaris 2.6 at version 1.0.1.
2. Recommendations
Sun recommends that sites running Solaris 2.6 and sites running SEA on
Solaris 2.5.1 upgrade the SEA software to SEA 1.0.3.
SEA 1.0.3 is bundled with Solaris 7. SEA 1.0.3 is available for Solaris
2.6, 2.6_x86, 2.5.1, and 2.5.1_x86 and may be downloaded from:
http://www.sun.com/solstice/products/ent.agents/
Sun also recommends that sites running SEA 1.0 on Solaris 2.4 and 2.5
either disable SEA (see section 3) or upgrade the operating system to
Solaris 7 if possible. Sites upgrading to Solaris 2.5.1 or 2.6 may
obtain SEA 1.0.3 from the URL listed above.
3. Workaround
Sun recommends that you disable SEA on vulnerable systems until
SEA 1.0.3 is installed.
To determine if your system is using SEA, use pkginfo on one of the
following SEA packages: SUNWmibii, SUNWsacom, SUNWsadmi, SUNWsasnm.
For example, on SEA 1.0 and 1.0.1, a pkginfo on SUNWmibii will display
as follows:
% pkginfo SUNWmibii
system SUNWmibii Solstice Enterprise Agent SNMP daemon
On SEA 1.0.2:
% pkginfo SUNWmibii
system SUNWmibii Solstice Enterprise Agents 1.0.2 SNMP daemon
To disable SEA, perform the following steps:
% su
Password:
# /etc/init.d/init.snmpdx stop
# mv /etc/rc3.d/S76snmpdx /etc/rc3.d/DISABLED_S76snmpdx
