CVE-2021-31850

Estado: ModificadaMedia (6.1)—

A denial-of-service vulnerability in Database Security (DBS) prior to 4.8.4 allows a remote authenticated administrator to trigger a denial-of-service attack against the DBS server. The configuration of Archiving through the User interface incorrectly allowed the creation of directories and files in Windows system directories and other locations where sensitive data could be overwritten. The former could lead to a DoS, whilst the latter could lead to data destruction on the DBS server.

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).
