CVE-2024-43545

Status: AnalyzedHigh (7.5)—

Windows Online Certificate Status Protocol (OCSP) Server Denial of Service Vulnerability

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).

🎯 ATT&CK techniques

How this vulnerability is exploited and what the attacker gains, in MITRE ATT&CK terms.

Vector CVSS con AV:N/AC:L/PR:N/UI:N indica explotación remota sin autenticación (T1190). CWE-400 (Uncontrolled Resource Consumption) y descripción DoS de OCSP Server confirman impacto T1499.004 (Application Exhaustion).

Inferred by our analysis agent from the official description, CVSS vector and CWE, and checked by a supervisor. May contain errors.
