Description
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing HTTP requests within the Traffic Management Microkernel (TMM) URI normalization feature. A remote attacker can create a specially crafted HTTP request to the virtual server associated with an HTTP profile, trigger memory corruption and crash the service or execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
Mitigation
Install updates from vendor's website.
