CVE-2020-5938


TITLE

BIG-IP  Vulnerability in cryptography

Trust: 0.8

sources: JVNDB: JVNDB-2020-012926

DESCRIPTION

On BIG-IP 13.1.0-13.1.3.4, 12.1.0-12.1.5.2, and 11.6.1-11.6.5.2, when negotiating IPSec tunnels with configured, authenticated peers, the peer may negotiate a different key length than the BIG-IP configuration would otherwise allow. BIG-IP Contains a cryptographic vulnerability.Information may be obtained. 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. There is a security vulnerability in F5 BIG-IP. Attackers can exploit this vulnerability to bypass data access restrictions and obtain sensitive information through the small IPsec key length
