CVE-2008-5275
HighSummary
Wielokrotne podatności na przejście do katalogu w funkcjonalności 'Rozpakuj archiwum' oraz 'Prześlij pliki i archiwa' w net2ftp 0.96 stable i 0.97 beta pozwalają zdalnym atakującym na tworzenie, odczytywanie lub usuwanie dowolnych plików poprzez użycie '..' w nazwie pliku w archiwum TAR lub ZIP. Może to być wykorzystane do wykonania kodu przez stworzenie pliku .php.
Risk Assessment
Atakujący mogą uzyskać dostęp do wrażliwych plików na serwerze, co może prowadzić do poważnych naruszeń bezpieczeństwa, w tym wykonania złośliwego kodu.
Recommendation
Zaleca się aktualizację do najnowszej wersji net2ftp oraz wdrożenie odpowiednich mechanizmów zabezpieczających przed przejściem do katalogu, aby zminimalizować ryzyko tego typu ataków.

Original NVD description (English source)
Multiple directory traversal vulnerabilities in the (a) "Unzip archive" and (b) "Upload files and archives" functionality in net2ftp 0.96 stable and 0.97 beta allow remote attackers to create, read, or delete arbitrary files via a .. (dot dot) in a filename within a (1) TAR or (2) ZIP archive. NOTE: this can be leveraged for code execution by creating a .php file.
