CVE-2025-4384 (GCVE-0-2025-4384)

Vulnerability from cvelistv5 – Published: 2025-05-06 15:59 – Updated: 2025-09-05 16:38
VLAI?
Summary
The MQTT add-on of PcVue fails to verify that a remote device’s certificate has not already expired or has not yet become valid. This allows malicious devices to present certificates that are not rejected properly. The use of a client certificate reduces the risk for random devices to take advantage of this flaw.
Severity ?
