CVE-2024-37040Network attack vector

Service interruption via malformed HTTP request

Published Jun 12, 2024 · Updated Aug 2, 2024

Classic buffer overflow in Schneider Electric SAGE RTU firmware C3414-500-S02K5_P8 and earlier allows remote authenticated users to fault devices. The web interface copies data from a malformed HTTP request without verifying that it fits the destination buffer; the affected handler is undisclosed. Access to the device web interface is required, and successful exploitation interrupts operation by causing a device fault.
