CVE-2024-25679

Estado: ModificadaMedia (6.5)—

In PQUIC before 5bde5bb, retention of unused initial encryption keys allows attackers to disrupt a connection with a PSK configuration by sending a CONNECTION_CLOSE frame that is encrypted via the initial key computed. Network traffic sniffing is needed as part of exploitation.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
