Em resumo

Uma falha na interface web do ASUS BMC permite que um administrador autenticado acesse arquivos fora do diretório pretendido usando path traversal. Um atacante com credenciais de admin consegue burlar as restrições de diretório e ler arquivos sensíveis do sistema.

Detalhe técnico

A função 'Get video file' na página de gerenciamento web do ASUS BMC não filtra adequadamente parâmetros de caminho fornecidos pelo usuário, possibilitando ataques de path traversal (CWE-22). Um atacante autenticado com privilégios de administrador pode enviar requisições malformadas contendo sequências de travessia (../) para acessar arquivos arbitrários além do diretório de vídeos.

Resumo gerado e traduzido por IA a partir da descrição oficial.
The specific function in ASUS BMC’s firmware Web management page (Get video file function) does not filter the specific parameter. As obtaining the administrator permission, remote attackers can use the means of path traversal to access system files.
