CVE-2020-1853Network attack vector

Authenticated file disclosure via unvalidated paths

Published Feb 17, 2020 · Updated Aug 4, 2024

Path traversal in Huawei GaussDB 200 6.5.1 allows remote authenticated users to download files through a network-accessible interface. Huawei has not identified the affected interface or code locus; it states only that supplied file paths are not sufficiently validated. Successful exploitation requires authenticated device access and exposes file contents by placing downloaded files in a specified directory.
