Service crash via crafted DelvsList input
Published Apr 7, 2023 · Updated Feb 11, 2025
Stack overflow in H3C Magic R100 firmware R100V100R005 allows remote authenticated users to crash the router through DelvsList input. The DelvsList handler at /goform/aspForm writes crafted input beyond a stack buffer; the disclosure does not name the copying function. High-privilege access to the web management interface is required, and exploitation interrupts router service without reported data disclosure or modification.
