CVE-2023-33468

Status: ModifiedCritical (9.1)—

KramerAV VIA Connect (2) and VIA Go (2) devices with a version prior to 4.0.1.1326 exhibit a vulnerability that enables remote manipulation of the device. This vulnerability involves extracting the connection confirmation code remotely, bypassing the need to obtain it directly from the physical screen.

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).
