CVE-2025-14558
HighSummary
Programy rtsol(8) i rtsold(8) nie weryfikują opcji listy wyszukiwania domen w wiadomościach ogłoszeń routerów, co skutkuje przekazywaniem ciała opcji do resolvconf(8) w niezmienionej formie. To może prowadzić do wykonania nieautoryzowanych poleceń powłoki.
Risk Assessment
Brak walidacji danych wejściowych w resolvconf(8) stwarza ryzyko wykonania złośliwego kodu, co może prowadzić do kompromitacji systemu. Organizacje mogą być narażone na ataki, które wykorzystują tę podatność do przejęcia kontroli nad systemem.
Recommendation
Zaleca się aktualizację oprogramowania do najnowszej wersji, która wprowadza odpowiednie walidacje danych wejściowych. Dodatkowo, warto rozważyć ograniczenie dostępu do programów rtsol(8) i rtsold(8) w celu minimalizacji ryzyka.

`@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)
The rtsol(8) and rtsold(8) programs do not validate the domain search list options provided in router advertisement messages; the option body is passed to resolvconf(8) unmodified. resolvconf(8) is a shell script which does not validate its input. A lack of quoting meant that shell commands pass as input to resolvconf(8) may be executed.
