F5 BIG‑IP devices leak config via SNMP

CVE-2019-6640 · published 7 years ago
Summary

Certain versions of F5 BIG‑IP traffic, acceleration, firewall, analytics, and access policy managers can send sensitive configuration details in plain text when using SNMP version 2. This means an attacker who can listen on the network could see passwords and settings. Update the devices to a version where the issue is fixed or disable SNMPv2 and use a secure management method.
