high Nessus Plugin ID 149078

Language:

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

The version of F5 Networks BIG-IP installed on the remote host is prior to 12.1.5.3 / 13.1.3.5 / 14.1.3.1 / 15.1.2 / 16.0.1.1 / 16.1.0. It is, therefore, affected by a vulnerability as referenced in the K18570111 advisory.

 - 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. (CVE-2021-23010)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
