CVE-2024-45700

Estado: ModificadaMedia (6)—

Zabbix server is vulnerable to a DoS vulnerability due to uncontrolled resource exhaustion. An attacker can send specially crafted requests to the server, which will cause the server to allocate an excessive amount of memory and perform CPU-intensive decompression operations, ultimately leading to a service crash.

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).
