TITLE

BIG-IP Buffer Overflow Vulnerability in Linux

Trust: 0.8

sources: JVNDB: JVNDB-2021-005131

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. BIG-IP Contains a classic buffer overflow vulnerability.Information is obtained, information is tampered with, and service is disrupted (DoS) It may be put into a state. F5 BIG-IP is an application delivery platform integrated with network traffic management, application security management, load balancing and other functions of the US company F5. A security vulnerability exists in the F5 BIG-IP that could be exploited by an attacker to run code
