K27400151:SNMP vulnerability CVE-2019-6613
Security Advisory
Original Publication Date: 01 May, 2019
Latest Publication Date: 07 May, 2019
Security Advisory Description
SNMP may expose sensitive configuration objects over insecure transmission
channels. This issue is exposed when a passphrase is used with various profile
types and is accessed using SNMPv2. (CVE-2019-6613)
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 would
not expose this issue, as remote SNMP access is disallowed by default.
Security Advisory Status
F5 Product Development has assigned ID 691767 (BIG-IP) to this vulnerability.
Additionally, BIG-IP iHealth may list Heuristic H27400151 on the Diagnostics >
Identified > Medium page.
