CVE-2022-32765Network attack vector

Authenticated command execution via unfiltered firmware metadata

Published Oct 25, 2022 · Updated Apr 15, 2025

OS command injection in Robustel R1510 3.1.16 and 3.3.0 allows remote authenticated users to execute arbitrary commands. The sysupgrade binary copies upgrade_obj.file_desc from an uploaded firmware file into an rpkg command and passes the resulting string to system() without filtering shell metacharacters. Administrator access and a precisely crafted firmware upload are required, after which injected commands run on the router.
