CVE-2021-22396

Estado: ModificadaAlta (7.8)—

There is a privilege escalation vulnerability in some Huawei products. Due to improper privilege management, a local attacker with common privilege may access some specific files in the affected products. Successful exploit will cause privilege escalation.Affected product versions include:eCNS280_TD V100R005C00,V100R005C10;eSE620X vESS V100R001C10SPC200,V100R001C20SPC200.
