Opened: Oct 12, 2018

Severity: 2-Critical


When an iRule disables HTTP with HTTP:disable, subsequent use of HTTP::cookie for that request will cause a TMM core dump.


Use of iRules in the above mentioned order will result in a TMM core. Traffic disrupted while tmm restarts.


1) HTTP profile is configured on the virtual. 2) HTTP:disable is called on request. 3) HTTP:cookie is then called on that request.


Do not call HTTP:cookie on requests that have had HTTP disabled by HTTP:disable
