CVE-2021-37122

Estado: ModificadaMedia (6.5)—

There is a use-after-free (UAF) vulnerability in Huawei products. An attacker may craft specific packets to exploit this vulnerability. Successful exploitation may cause the service abnormal. Affected product versions include:CloudEngine 12800 V200R005C10SPC800,V200R019C00SPC800;CloudEngine 5800 V200R005C10SPC800,V200R019C00SPC800;CloudEngine 6800 V200R005C10SPC800,V200R005C20SPC800,V200R019C00SPC800;CloudEngine 7800 V200R005C10SPC800,V200R019C00SPC800.

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).
