CVE-2024-21920

Estado: AnalizadaAlta (7.1)—

A memory buffer vulnerability in Rockwell Automation Arena Simulation could potentially let a threat actor read beyond the intended memory boundaries. This could reveal sensitive information and even cause the application to crash, resulting in a denial-of-service condition. To trigger this, the user would unwittingly need to open a malicious file shared by the threat actor.

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).
