    Which Sx number to take ?
    And, 1 Februray 2022 is very long before this critical october http alert ... no ?

    And same things for :

    Hi,
    I highly doubt that we will see an update for the EX2200 - it's been EoL for a Loooooooooooong time ;)
    Either use the latest Sx in the 12.3 branch and be okay with possible bugs / security issues or refresh the hardware to a non-EoL-System (EX2300 / EX4100-F for example) 

    For the EX2300 you can use the latest 21.2R3 Release (21.2R3-S2) which is stable and will not have the issue you mentioned (only up to S1 will have this issue).

    Hello again,

    And thanks a lots for your advise..

    For the EX2300,  the 21.2R3 branch is better than the 20.4R3 branch  ?   not to "heavy" for the hardware (as it starts with the  15.3 branch) .

    So you could see that the JTAC recommanded software don't tell about the SX to take that could be a question for people like me... Or, the policy is to take the last SX but thez do not say it.... :-)

    Bye !

    For these older platforms the best response to these CVE is to turn off jweb and manage the device only via ssh instead.
