CVE-2022-28127Network attack vector

Arbitrary file deletion via absolute-path input

Published Jun 30, 2022 · Updated Apr 15, 2025

Improper input validation in Robustel R1510 3.3.0 allows remote authenticated users to delete arbitrary files through its web API. The /ajax/remove/ handler rejects file_name values containing '..' but accepts absolute paths, interpolates them into rm -rf, and executes the command. Access requires network reachability to the web GUI and an account permitted to edit functions; deletion can remove files or directories on the router.
