K40443301:SNMP vulnerability CVE-2019-6640 

Security Advisory

Original Publication Date: 02 Jul, 2019

Security Advisory Description

SNMP exposes sensitive configuration objects over insecure transmission
channels. This issue is exposed when a passphrase is inserted into various
profile types and accessed using SNMPv2. (CVE-2019-6640)

Impact

An attacker with direct SNMP access to a BIG-IP system, or an attacker with a
privileged network position (man-in-the-middle) may be able to obtain the
passphrases used within configuration profiles.  Default configurations do not
expose this issue; remote SNMP access is disallowed by default.

Security Advisory Status

F5 Product Development has assigned ID 753796 (BIG-IP) to this vulnerability.

To determine if your product and version have been evaluated for this
vulnerability, refer to the Applies to (see versions) box. To determine if your
release is known to be vulnerable, the components or features that are affected
by the vulnerability, and for information about releases or hotfixes that
address the vulnerability, refer to the following table. For more information
about security advisory versioning, refer to K51812227: Understanding Security
Advisory versioning.

Security Advisory Recommended Actions

If you are running a version listed in the Versions known to be vulnerable
column, you can eliminate this vulnerability by upgrading to a version listed
in the Fixes introduced in column. If the table lists only an older version
than what you are currently running, or does not list a non-vulnerable version,
then no upgrade candidate currently exists.

Mitigation

To mitigate this vulnerability, you can implement SNMPv3 with secure AES-128
encryption. For more information, refer to K13625: Overview of SNMPv3 agent
access.
