CVE-2020-16098

Status: ModifiedCritical (9.8)—

It is possible to enumerate access card credentials via an unauthenticated network connection to the server in versions of Command Centre v8.20 prior to v8.20.1166(MR3), versions of 8.10 prior to v8.10.1211(MR5), versions of 8.00 prior to v8.00.1228(MR6), all versions of 7.90 and earlier. These credentials can then be used to encode low security cards to be used by the system where insecure card technologies are supported.

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).
