CVE-2022-23018

Status: ModifiedHigh (7.5)—

On BIG-IP AFM version 16.1.x before 16.1.2, 15.1.x before 15.1.4.1, 14.1.x before 14.1.4.5, and 13.1.x beginning in 13.1.3.4, when a virtual server is configured with both HTTP protocol security and HTTP Proxy Connect profiles, undisclosed requests can cause the Traffic Management Microkernel (TMM) to terminate. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
