CVE-2012-1864
HighSummary
Podatność w win32k.sys w trybie jądra systemu Microsoft Windows umożliwia lokalnym użytkownikom uzyskanie podwyższonych uprawnień poprzez odpowiednio przygotowaną aplikację. Dotyczy to systemów 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.
Risk Assessment
Organizacja może być narażona na nieautoryzowany dostęp do systemów przez lokalnych użytkowników, co może prowadzić do poważnych naruszeń bezpieczeństwa. Wzrost uprawnień może umożliwić wykonanie złośliwego kodu z wyższymi uprawnieniami.
Recommendation
Zaleca się aktualizację systemów operacyjnych do najnowszych wersji, które zawierają poprawki bezpieczeństwa. Należy również ograniczyć dostęp lokalnych użytkowników do krytycznych zasobów systemowych.

`@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.
