Authenticated memory corruption via set_macfilter stack overflow
Published Jun 6, 2026 · Updated Jun 6, 2026
Stack-based buffer overflow in jdcweb_rpc on JD Cloud Box AX6600 4.5.3.r4546 allows remote authenticated users to corrupt memory. The set_macfilter function processes an undisclosed input without enforcing the destination stack buffer's bounds. Low-privilege access to the network RPC service is required; the public advisory establishes memory corruption but not code execution or a specific crash mode.
