New! CVE Severity Now Using CVSS v3

The calculated severity for CVEs has been updated to use CVSS v3 by default. CVEs that do not have a CVSS v3 score will fall back CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Description

On versions 16.0.x before 16.0.1.1, 15.1.x before 15.1.2, 14.1.x before 14.1.3.1, 13.1.x before 13.1.3.5, and 12.1.x before 12.1.5.3, when the BIG-IP ASM/Advanced WAF system processes WebSocket requests with JSON payloads using the default JSON Content Profile in the ASM Security Policy, the BIG-IP ASM bd process may produce a core file. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
