## Technical details

The /setUserConfig SOAP-RPC handler in firmware 3.3.2.4 fails to verify session privilege level on empty-body POST requests, allowing authenticated users without administrative rights to downgrade the admin password to default and corrupt in-memory auth state. Attack requires network access and prior authentication; successful exploitation grants administrative control until device reload.
