Quick assessment

Affected
n/a BIG-IP
Exploitation
Confirmed exploitation in the wild; remediate immediately
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

F5 BIG-IP是美国F5公司的一款集成了网络流量管理、应用程序安全管理、负载均衡等功能的应用交付平台。 F5 BIG-IP 存在缓冲区错误漏洞，流量管理微内核(Traffic Management Microkernel, TMM) URI 的规范化可能会错误地处理对虚拟服务器的请求，从而触发缓冲区溢出，导致拒绝服务攻击。在一定条件下，可能绕过基于URL的访问控制，造成远程代码执行。

Source: CVE Program / CVE List V5
Vulnerability Description
On BIG-IP versions 16.0.x before 16.0.1.1, 15.1.x before 15.1.2.1, 14.1.x before 14.1.4, 13.1.x before 13.1.3.6, and 12.1.x before 12.1.5.3, undisclosed requests to a virtual server may be incorrectly handled by the Traffic Management Microkernel (TMM) URI normalization, which may trigger a buffer overflow, resulting in a DoS attack. In certain situations, it may theoretically allow bypass of URL based access control or remote code execution (RCE). Note: Software versions which have reached End of Software Development (EoSD) are not evaluated.
