In short
Schweitzer Engineering Laboratories relays contain hidden, undocumented features that can be accessed by users with administrator privileges, potentially causing the relay to behave unpredictably or malfunction.
Technical detail
CWE-1242 addresses inclusion of undocumented features in protected firmware/hardware. An authenticated attacker with privileged access can invoke these hidden functions to trigger unexpected relay behavior, affecting critical power protection infrastructure; exploitation requires administrative credentials and direct system access.
Summary generated and translated by AI from the official description.
Inclusion of undocumented features vulnerability accessible when logged on with a privileged access level on the following Schweitzer Engineering Laboratories relays could allow the relay to behave unpredictably:
SEL-700BT Motor Bus Transfer Relay, SEL-700G Generator Protection Relay, SEL-710-5 Motor Protection Relay, SEL-751 Feeder Protection Relay, SEL-787-2/-3/-4 Transformer Protection Relay, SEL-787Z High-Impedance Differential Relay
. See product instruction manual appendix A dated 20240308 for more details regarding the SEL-751 Feeder Protection Relay. For more information for the other affected products, see their instruction manuals dated 20240329.
