SNMPv3 Authentication Bypass Vulnerability in snmpd(1M)
1. Impact
A security vulnerability in the System Management Agent (SMA) SNMP daemon
(snmpd(1M)) that shipped with Solaris may allow a local or remote
unprivileged user to access unauthorized information.
This issue is described in the following document:
2. Contributing Factors
This issue can occur in the following releases:
SPARC Platform:
- Solaris 10 without patch 120272-21
- OpenSolaris based upon builds snv_01 or later
x86 Platform:
- Solaris 10 without patch 120273-23
- OpenSolaris based upon builds snv_01 or later
Notes:
1. Solaris 8 and Solaris 9 do not ship with the Net-SNMP software
and thus are not impacted by this issue.
2. The Net-SNMP software was not bundled with Solaris prior to
Solaris10. However, customers who have built and/or installed a
vulnerable version of Net-SNMP on any version of Solaris are at risk.
(See the Net-SNMP web site to download the latest version of Net-SNMP
which addresses this issue).
3. The Solaris 10 patches which address this vulnerability do not
increment the version of Net-SNMP. The version of Net-SNMP supplied
with the patches will still be reported as 5.0.9.
4. This issue only affects systems which have the SUNWsmagt package
installed. To determine if the SUNWsmagt package is installed on the
system, the following command can be used:
$ pkginfo -l SUNWsmagt
PKGINST: SUNWsmagt
NAME: System Management Agent files and libraries
CATEGORY: system
VERSION: 1.0,REV=2005.01.08.05.16
5. Only OpenSolaris installations including the affected binary
"/usr/sfw/lib/libnetsnmp.so.5.0.9" are affected by this issue.
6. OpenSolaris distributions may include additional bug fixes above and
beyond the build from which it was derived. The base build can be
derived as follows:
$ uname -a
SunOS phys-node-1 5.11 snv_86 i86pc i386 i86pc
3. Symptoms
There are no predictable symptoms that would indicate this issue has being exploited to gain access to unauthorized information.
4. Workaround
There is no workaround for this issue. Please see the Resolution section below.
5. Resolution
This issue is addressed in the following releases:
SPARC Platform:
- Solaris 10 with patch 120272-21 or later
- OpenSolaris based upon builds snv_93 or later
x86 Platform:
- Solaris 10 with patch 120273-23 or later
- OpenSolaris based upon builds snv_93 or later
