Technical details

The vulnerability exists in the ubus JSON-RPC management interface (TCP port 23355), specifically in the routerd.wificfg_get and routerd.get_rand_key methods, which lack proper authentication checks. An unauthenticated attacker with local network access can call these methods to retrieve wireless configuration data including credentials. The issue is resolved in firmware version 1.0.7.260821.161908 and later.
