CVE-2008-5155
HighSummary
CVE-2008-5155 dotyczy skryptu mail2sms.sh w smsclient 2.0.8z, który pozwala lokalnym użytkownikom na nadpisywanie dowolnych plików poprzez atak symlink na pliki tymczasowe /tmp/header.##### oraz /tmp/body.#####. Umożliwia również dodawanie danych do dowolnych plików poprzez atak symlink na plik tymczasowy /tmp/sms.log.
Risk Assessment
Atakujący może wykorzystać tę podatność do nadpisania ważnych plików systemowych lub logów, co może prowadzić do utraty danych lub naruszenia integralności systemu. To stwarza poważne ryzyko dla bezpieczeństwa organizacji.
Recommendation
Zaleca się ograniczenie dostępu do skryptu mail2sms.sh oraz wprowadzenie kontroli nad tworzeniem plików tymczasowych, aby zapobiec atakom symlink. Należy również rozważyć aktualizację do nowszej wersji smsclient, jeśli jest dostępna.
