An attacker may use a specially crafted message to force Relion 650 series (versions 1.3.0.5 and prior) or Relion 670 series (versions 1.2.3.18, 2.0.0.11, 2.1.0.1 and prior) to reboot, which could cause a denial of service.
A vulnerability exists in the input validation of the GOOSE
messages where out of range values received and processed
by the IED caused a reboot of the device. In order for an
attacker to exploit the vulnerability, goose receiving blocks need
to be configured.
A vulnerability exists in the Relion update package signature validation. A tampered update package could cause the IED to restart. After restart the device is back to normal operation.
An attacker could exploit the vulnerability by first gaining access to
the system with security privileges and attempt to update the IED
with a malicious update package. Successful exploitation of this
vulnerability will cause the IED to restart, causing a temporary Denial of Service.
