CVE-2011-4409
HighSummary
Klient Ubuntu One dla systemów Ubuntu 10.04 LTS, 11.04, 11.10 i 12.04 LTS nieprawidłowo weryfikuje certyfikaty SSL, co umożliwia zdalnym atakującym podszywanie się pod serwer oraz modyfikowanie lub odczytywanie wrażliwych informacji za pomocą ataku typu man-in-the-middle (MITM).
Risk Assessment
Brak odpowiedniej weryfikacji certyfikatów SSL stwarza ryzyko przechwycenia danych przez atakujących, co może prowadzić do utraty poufności informacji oraz naruszenia integralności danych.
Recommendation
Zaleca się aktualizację klienta Ubuntu One do najnowszej wersji, która poprawia weryfikację certyfikatów SSL oraz wdrożenie dodatkowych środków zabezpieczających, aby zminimalizować ryzyko ataków MITM.

Original NVD description (English source)
The Ubuntu One Client for Ubuntu 10.04 LTS, 11.04, 11.10, and 12.04 LTS does not properly validate SSL certificates, which allows remote attackers to spoof a server and modify or read sensitive information via a man-in-the-middle (MITM) attack.
