CVE-2012-3512
HighSummary
Munin w wersjach przed 2.0.6 przechowuje pliki stanu wtyczek, które działają jako root, w tym samym katalogu z uprawnieniami do zapisu dla grupy, co wtyczki nie-root. Umożliwia to lokalnym użytkownikom wykonanie dowolnego kodu poprzez zastąpienie pliku stanu, co zostało zademonstrowane przy użyciu wtyczki smart_.
Risk Assessment
Podatność ta stwarza ryzyko dla systemów, w których lokalni użytkownicy mogą uzyskać dostęp do plików stanu, co może prowadzić do nieautoryzowanego wykonania kodu i potencjalnego przejęcia kontroli nad systemem.
Recommendation
Zaleca się aktualizację Munin do wersji 2.0.6 lub nowszej oraz ograniczenie dostępu do katalogów z plikami stanu wtyczek, aby zminimalizować ryzyko związane z tą podatnością.

Original NVD description (English source)
Munin before 2.0.6 stores plugin state files that run as root in the same group-writable directory as non-root plugins, which allows local users to execute arbitrary code by replacing a state file, as demonstrated using the smart_ plugin.
