F5 Networks BIG-IP : SNMP vulnerability (K40443301)

medium Nessus Plugin ID 126402

Language:

Synopsis

The remote device is missing a vendor-supplied security patch.

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.

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution K40443301.
