CVE-2021-37445Public exploitNetwork attack vector

Authenticated file disclosure via logprop path traversal

Published Jul 25, 2021 · Updated Aug 4, 2024

Path traversal in NCH Quorum 2.03 and earlier allows remote authenticated users to read arbitrary files through the web interface. The logprop handler accepts parent-directory sequences in its file parameter and returns the referenced file without constraining the path. A valid session is required, and readable files are limited by the Windows account running the server, including other NCH credential files.
