Opened: Mar 15, 2018

Severity: 3-Major


When a request including binary null character has been sent to an remote logger, configured for ASM, the request will arrive to the remote destination and will be truncated exactly at binary NULL character.


Partial request is logged at the remote logger destination.


-- ASM provisioned. -- ASM policy attached to a virtual server. -- ASM remote logger attached to a virtual server. -- Request including binary NULL character is sent to the remote logger destination.



Fix Information

Binary NULL character is now escaped before being sent to the remote logger destination, so the request is no longer truncated.
