CVE-2021-22404Network attack vector

Remote file disclosure via directory traversal

Published Oct 28, 2021 · Updated Aug 3, 2024

Directory traversal in Huawei EMUI 9.1.0, 9.1.1, 10.0.0, 10.1.0, 10.1.1, and 11.0.0 allows remote attackers to read data. Huawei has not published the affected component or the pathname operation that inadequately confines attacker-controlled input. The published assessment treats exploitation as unauthenticated and network-reachable, with confidentiality impact only and no reported integrity or availability effect.
