CVE-2021-20072Public exploitNetwork attack vector

Arbitrary file read and deletion via path traversal

Published Feb 16, 2021 · Updated Aug 3, 2024

Path traversal in RACOM M!DGE firmware 4.4.40.105 allows remote authenticated users to read and delete arbitrary files. The /admin/downloadFile.php handler accepts ../ sequences in dfile, returns the referenced file as root, and deletes it unless wipe is 0. A privileged web account is required; disclosure includes root-readable data, while deletion can make the router unusable.
