Arbitrary file disclosure via path traversal
Published Jan 10, 2022 · Updated Aug 4, 2024
Path traversal in dst-admin 1.3.0 allows remote attackers to read arbitrary server files through an unauthenticated HTTP request. The /images;/../backup/download route bypasses authentication and accepts ../ sequences in fileName without confining the resolved path. No account or password is required, and disclosed files can include operating-system data such as /etc/passwd.
