CVE-2021-46424Public exploitNetwork attack vector

Unauthenticated file deletion via unrestricted DELETE requests

Published Apr 27, 2022 · Updated Aug 4, 2024

Arbitrary file deletion in Telesquare TLR-2005KSH 1.0.0 allows remote attackers to delete device files via HTTP DELETE requests. The web interface accepts an unauthenticated DELETE request whose path names the file to remove, without restricting deletion to an authorized file set. Network access to the device's HTTP service is sufficient, and deletion of internal system files can cause data loss or interrupt service.
