"A vulnerability exists in the HCI IEC 60870-5-104 function included in
certain versions of the RTU500 series product. The vulnerability can
only be exploited, if the HCI 60870-5-104 is configured with support
for IEC 62351-5 and the CMU contains the license feature Advanced
security' which must be ordered separately. If these preconditions are
fulfilled, an attacker could exploit the vulnerability by sending a
specially crafted message to the RTU500, causing the targeted RTU500
CMU to reboot. The vulnerability is caused by a missing input data
validation which eventually if exploited causes an internal buffer to
overflow in the HCI IEC 60870-5-104 function.

This plugin only works with Tenable.ot.
