A vulnerability in the Traffic Management Microkernel (TMM) URI parser library of multiple F5 BIG-IP products could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on a targeted system.
The vulnerability is due to improper processing of HTTP requests by an affected system. An attacker could exploit this vulnerability by sending a crafted HTTP request to the targeted system. An exploit could cause the TMM component of the system to generate a core file and restart, resulting in a DoS condition.
F5 has confirmed the vulnerability and released software updates.
