    Disclosure

    A walkthrough of a recurring type-confusion pattern in Windows RPC servers: when an interface accepts an FC_BINDING_CONTEXT handle without checking its object type, attackers can feed one context-handle type where another is expected. The pattern yielded CVE-2025-48815 (ssdpsrv), CVE-2025-53143 (MQQM) and CVE-2025-54104 (mpssvc). https://core-jmp.org/2026/06/from-context-handle-to-type-confusion-windows-rpc-2/

    Post summary

    The post outlines a recurring type‑confusion vulnerability pattern in Windows RPC servers, explaining how attackers can misuse FC_BINDING_CONTEXT handles and listing three resulting CVEs, and provides a link to a detailed walkthrough, but no exploit tools, patch, or active exploitation reports are mentioned.
