CVE-2021-39995

Estado: ModificadaMedia (6.5)—

Some Huawei products use the OpenHpi software for hardware management. A function that parses data returned by OpenHpi contains an out-of-bounds read vulnerability that could lead to a denial of service. Affected product versions include: eCNS280_TD V100R005C10; eSE620X vESS V100R001C10SPC200, V100R001C20SPC200, V200R001C00SPC300.

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).
