CVE-2012-1893
HighSummary
W win32k.sys w sterownikach trybu jądra systemu Microsoft Windows XP SP2 i SP3, Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2, R2 i R2 SP1 oraz Windows 7 Gold i SP1 występuje niewłaściwa walidacja parametrów wywołania podczas tworzenia procedury hook, co pozwala lokalnym użytkownikom na uzyskanie uprawnień za pomocą spreparowanej aplikacji.
Risk Assessment
Podatność ta może prowadzić do eskalacji uprawnień przez lokalnych użytkowników, co stwarza poważne zagrożenie dla integralności systemu i danych organizacji.
Recommendation
Zaleca się aktualizację systemów operacyjnych do najnowszych wersji, które zawierają poprawki bezpieczeństwa eliminujące tę podatność.

`@zereight/mcp-gitlab` is a Model Context Protocol server for GitLab. Prior to version 2.1.27, the SSE transport mode (`SSE=true`) exposes all MCP tools without any authentication. The `upload_markdown` tool reads arbitrary files from the server's local filesystem via an unsanitized `file_path` parameter and uploads them to a GitLab project.
