Cisco ISE 3.1 patch3 installation

[milos_p]

Hi guys,

I have fresh Cisco ISE 3.1 installation with patch1 and hotfix ise-apply-CSCwa47133_3.1.0.518_patch1 (CSCwa47133 related to Apache Log4j2) applied as well.

It is not clear to me what's the correct procedure to install patch3 in this case.

Should I just install patch3 on top of my installation?

Should I first remove Log4j2 hotfix, and then apply patch3? I guess patch3 has already integrated hotfix for Log4j2?

Anyone applied patch3 already, run into some problems?

Thanks a lot!

 - You don't need to remove the hotfix , https://bst.cloudapps.cisco.com/bugsearch/bug/CSCwa47140 , mentions 3.1 patch2 as being fixed, since patches are cumulative that would then normally apply for patch 3 too. Note that if business context requires authoritative answer then contact Cisco TAC.

Hi,

What troubles me is this:

https://www.cisco.com/c/en/us/td/docs/security/ise/3-1/release_notes/b_ise_31_RN.html#id_82860

"If you have installed a hot patch on Cisco ISE 3.1, you must roll back the hot patch before installing a patch. Otherwise, the services might not be started due to integrity check security issue. "

 - If  the rollback is easy execute it and go  ahead  with patch3 which then should have the fix installed, as stated if stronger guidance is needed, then work with TAC.

Hi guys,

Just to post an update.

I first removed hotfix, as recommended in release notes.

I installed Patch3 successfully, no issues so far.

It fixed the bug with Guest sponsored portal with iOS devices getting stuck on "cancel" button (there was workaround with the script) that I was hitting before.
