Trust: 0.8

sources: JVNDB: JVNDB-2018-006247

DESCRIPTION

Under certain conditions, on F5 BIG-IP ASM 13.1.0-13.1.0.5, Behavioral DOS (BADOS) protection may fail during an attack. F5 BIG-IP ASM is prone to a remote denial-of-service vulnerability. An attacker can exploit this issue to cause a denial-of-service condition, denying service to legitimate users. BIG-IP ASM 13.1.0 through 13.1.0.5 are vulnerable. F5 BIG-IP ASM (Application Security Manager) is a Web Application Firewall (WAF) of F5 Corporation in the United States. It provides secure remote access, protects emails, simplifies Web access control, and enhances network and application performance. F5 BIG-IP ASM version 13.1.0 to 13.1.0.5 has a security vulnerability, which is caused by the program not running normally with BADoS protection
