Description

A flaw was found in the `procd` component of OpenWrt. A highly privileged local attacker can bypass environment variable filtering in the `hotplug_call` function by injecting an arbitrary `PATH` variable. This vulnerability, caused by an incorrect string comparison, allows the attacker to control which binaries are executed by `procd`-invoked scripts running with elevated privileges, potentially leading to privilege escalation.
