TITLE

F5 BIG-IP SCTP Denial of Service Vulnerability

Trust: 0.6

sources: CNVD: CNVD-2025-20727

DESCRIPTION

When a Stream Control Transmission Protocol (SCTP) profile is configured on a virtual server, undisclosed requests can cause an increase in memory resource utilization. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated. F5 BIG-IP is an application delivery platform from F5 that integrates network traffic orchestration, load balancing, intelligent DNS, and remote access policy management. F5 BIG-IP SCTP contains a denial of service vulnerability. An attacker could exploit this vulnerability to launch a denial of service attack
