The SIGNUM controller from Elber satellite equipment demodulates one or two DVB-S/ S2 signals up to 32APSK (single/multi-stream), achieving 256 KS/s as minimum symbol rate. The TS demodulated signals can be aligned and configured in 1+1 seamless switching for redundancy. Redundancy can also be achieved with external ASI and TSoIP inputs. Signum supports MPEG-1 LI/II audio codec, providing analog and digital outputs; moreover, it’s possible to set a data PID to be decoded and passed to the internal RDS encoder, generating the dual MPX FM output.
The device suffers from an authentication bypass vulnerability through a direct and unauthorized access to the password management functionality. The issue allows attackers to bypass authentication by manipulating the set_pwd endpoint that enables them to overwrite the password of any user within the system. This grants unauthorized and administrative access to protected areas of the application compromising the device's system security.
