CVE-2012-3292
HighSummary
GridFTP w Globus Toolkit (GT) przed wersją 5.2.2 nieprawidłowo sprawdza wartość zwracaną przez funkcję getpwnam_r, gdy zdefiniowane są określone makra autoconf. Może to pozwolić zdalnym atakującym na uzyskanie uprawnień poprzez logowanie się jako użytkownik, który nie istnieje, co powoduje, że GridFTP działa jako ostatni użytkownik w pliku haseł.
Risk Assessment
Organizacja może być narażona na nieautoryzowany dostęp i eskalację uprawnień, co może prowadzić do poważnych naruszeń bezpieczeństwa. Atakujący mogą wykorzystać tę podatność do przejęcia kontroli nad systemem.
Recommendation
Zaleca się aktualizację Globus Toolkit do wersji 5.2.2 lub nowszej, aby usunąć tę podatność. Dodatkowo, warto przeprowadzić audyt konfiguracji i uprawnień użytkowników w systemie.

Original NVD description (English source)
The GridFTP in Globus Toolkit (GT) before 5.2.2, when certain autoconf macros are defined, does not properly check the return value from the getpwnam_r function, which might allow remote attackers to gain privileges by logging in with a user that does not exist, which causes GridFTP to run as the last user in the password file.
