TITLE

BIG-IP Race condition vulnerabilities in

Trust: 0.8

sources: JVNDB: JVNDB-2020-004820

DESCRIPTION

On BIG-IP 15.0.0-15.0.1.3, 14.1.0-14.1.2.3, 13.1.0-13.1.3.3, 12.1.0-12.1.5.1, and 11.6.1-11.6.5.1, a race condition exists where mcpd and other processes may make unencrypted connection attempts to a new configuration sync peer. The race condition can occur when changing the ConfigSync IP address of a peer, adding a new peer, or when the Traffic Management Microkernel (TMM) first starts up. BIG-IP Exists in a race condition vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (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. A remote attacker could exploit this vulnerability to take control of the connection, impersonate a peer-to-peer trusted device, and extract or modify sensitive information on the system. The following products and versions are affected: 15.0.0 to 15.0.1.3, 14.1.0 to 14.1.2.3, 13.1.0 to 13.1.3.3, 12.1.0 to 12.1.5.1 and 11.6.1 Version to version 11.6.5.1. F5 BIG-IP could allow a remote malicious user to bypass security restrictions, caused by a race condition in the mcpd
