Description	Insecure generation of credentials in the local SAT (Technical Support) access functionality of the Ingecon Sun EMS Board. The vulnerability arose because the secret access credentials were not based on a secure cryptographic scheme, but rather on a weak hashing algorithm, which could allow an attacker to carry out a privilege escalation.
