Fixes
Solution
The following software releases have been updated to resolve this specific issue: Junos OS: 12.3R12-S20, 15.1R7-S11, 18.3R3-S6, 18.4R2-S9, 18.4R3-S10, 19.1R2-S3, 19.1R3-S7, 19.2R1-S8, 19.2R3-S4, 19.3R3-S4, 19.4R2-S5, 19.4R3-S6, 20.1R3-S2, 20.2R3-S3, 20.3R3-S1, 20.4R3, 21.1R2-S2, 21.1R3, 21.2R1-S2, 21.2R2, 21.3R1, and all subsequ ent releases. Junos OS Evolved: 21.2R3-EVO, 21.3R2-EVO, 21.4R1-EVO, and all subsequent releases.
Workaround
There are no workarounds for this issue. For V1, V2 you can reduce the risk of exploitation by configuring the client-list to limit access to network management system (NMS) machines. See the Network Management and Monitoring Guide for further instructions. example: [snmp client-list client-list-name "ip-addresses";] For V3 you can reduce the risk of exploitation by configuring SNMP security to trusted devices only. For any release of SNMP you can reduce the risk of exploitation by implementing source and destination IP filter rules as well as using Read Only communities where possible. Regardless of these risk reduction methods, an attacker able to spoof trusted IP addresses can send the attack to an exposed and reachable SNMP RW community.
