CVE-2025-66480
CriticalSummary
W Wildfire IM, przed wersją 1.4.3, występuje krytyczna podatność w komponencie im-server związana z funkcjonalnością przesyłania plików. Aplikacja udostępnia punkt końcowy (/fs), który obsługuje przesyłanie plików wieloczęściowych, ale nieprawidłowo sanitizuje nazwę pliku podaną przez użytkownika, co pozwala na ataki.
Risk Assessment
Podatność ta umożliwia atakującemu zapisanie dowolnych plików w systemie plików serwera, co może prowadzić do zdalnego wykonania kodu (RCE) i całkowitego przejęcia kontroli nad serwerem. To stwarza poważne zagrożenie dla bezpieczeństwa organizacji.
Recommendation
Zaleca się aktualizację Wildfire IM do wersji 1.4.3 lub nowszej, aby usunąć tę podatność. Dodatkowo, warto wdrożyć mechanizmy ograniczające możliwość przesyłania plików oraz odpowiednio sanitizować nazwy plików.

Original NVD description (English source)
Wildfire IM is an instant messaging and real-time audio/video solution. Prior to 1.4.3, a critical vulnerability exists in the im-server component related to the file upload functionality found in com.xiaoleilu.loServer.action.UploadFileAction. The application exposes an endpoint (/fs) that handles multipart file uploads but fails to properly sanitize the filename provided by the user. Specifically, the writeFileUploadData method directly concatenates the configured storage directory with the filename extracted from the upload request without stripping directory traversal sequences (e.g., ../../). This vulnerability allows an attacker to write arbitrary files to any location on the server's filesystem where the application process has write permissions. By uploading malicious files (such as scripts, executables, or overwriting configuration files like authorized_keys or cron jobs), an attacker can achieve Remote Code Execution (RCE) and completely compromise the server.
