CVE-2008-5103
HighSummary
Wersje python-vm-builder i ubuntu-vm-builder w VMBuilder 0.9 w Ubuntu 8.10 pomijają opcję -e przy wywoływaniu chpasswd z argumentem root:!, co ustawia konto root z hasłem w postaci jawnej jako !. To umożliwia atakującym obejście zamierzonych ograniczeń logowania.
Risk Assessment
Organizacja może być narażona na nieautoryzowany dostęp do konta root, co stwarza poważne zagrożenie dla bezpieczeństwa systemu i danych.
Recommendation
Zaleca się aktualizację do nowszej wersji VMBuilder, która poprawia tę lukę, oraz przegląd zabezpieczeń konta root w celu zapewnienia odpowiednich środków ochrony.

Original NVD description (English source)
The (1) python-vm-builder and (2) ubuntu-vm-builder implementations in VMBuilder 0.9 in Ubuntu 8.10 omit the -e option when invoking chpasswd with a root:! argument, which configures the root account with a cleartext password of ! (exclamation point) and allows attackers to bypass intended login restrictions.
