CVE-2025-14769
HighSummary
W niektórych przypadkach, handler `tcp-setmss` może zwolnić dane pakietu i zgłosić błąd bez zatrzymywania silnika przetwarzania reguł. Kolejna reguła może następnie zezwolić na ruch po usunięciu danych pakietu, co prowadzi do dereferencji wskaźnika NULL.
Risk Assessment
Złośliwie skonstruowane pakiety wysyłane z zdalnego hosta mogą prowadzić do ataku typu Denial of Service (DoS), jeśli używana jest dyrektywa `tcp-setmss`, a kolejna reguła zezwala na przepuszczenie ruchu.
Recommendation
Zaleca się przegląd i aktualizację reguł przetwarzania ruchu, aby zapobiec sytuacjom, w których ruch może być dozwolony po zwolnieniu danych pakietu.

`@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.

`@zereight/mcp-gitlab` is a Model Context Protocol server for GitLab. Versions prior to 2.1.30 expose the Streamable HTTP MCP endpoint without an effective Host or Origin allowlist. A malicious web page can use DNS rebinding to route browser requests to a victim's local MCP listener while preserving an attacker-controlled `Host` and `Origin`.
Original NVD description (English source)
In some cases, the `tcp-setmss` handler may free the packet data and throw an error without halting the rule processing engine. A subsequent rule can then allow the traffic after the packet data is gone, resulting in a NULL pointer dereference. Maliciously crafted packets sent from a remote host may result in a Denial of Service (DoS) if the `tcp-setmss` directive is used and a subsequent rule would allow the traffic to pass.
