TMOS v13 Update: ASM::enable / ASM::disable commands are causing TCL exemptions...

Hi Kai,

I encounter the same issue as you (13.0 HF2) Example : TCL error: /Common/asm_irule - while executing "ASM::enable /Common/security_xxx"

I have a LTP assigned with my "default" Policy (LTP created by the system). Once assigned, I would like to change the Policy on "HTTP::host" event and error occurs...

I saw this issue occured ramdomly... if I change my default Policy, no issue. I have checked the difference between both and the root cause is ....:

Detect Session Hijacking by Device ID Tracking (Security ›› Application Security : Sessions and Logins : Session Tracking)

You have to ENABLE it. Very very strange, but it works for me.

Could you please test it ? Let me know If you have the same behavior.

Jeremy.
