CVE-2021-26112

Estado: ModificadaCrítica (9.8)—

Multiple stack-based buffer overflow vulnerabilities [CWE-121] both in network daemons and in the command line interpreter of FortiWAN before 4.5.9 may allow an unauthenticated attacker to potentially corrupt control data in memory and execute arbitrary code via specifically crafted requests.

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).
