07 Remediation
The vendor was unresponsive to multiple communication attempts during over one year of responsible disclosure after submitting the technical details to them. It is unknown to SEC Consult whether a patch is available. Customers of SIMCom are urged to reach out to their contact person at SIMCom or distributors to demand a patch which removes the backdoor command.
