CVE-2008-5617
HighSummary
Obsługa listy kontroli dostępu (ACL) w rsyslog w wersjach od 3.12.1 do 3.20.0 oraz 4.1.0 i 4.1.1 nie przestrzega dyrektywy $AllowedSender. To pozwala zdalnym atakującym na obejście zamierzonych ograniczeń dostępu oraz na fałszowanie komunikatów logów lub generowanie dużej liczby fałszywych wiadomości.
Risk Assessment
Organizacja może być narażona na fałszywe logi, co utrudnia monitorowanie i analizę zdarzeń bezpieczeństwa. Może to prowadzić do nieautoryzowanego dostępu i utraty integralności danych.
Recommendation
Zaleca się aktualizację rsyslog do najnowszej wersji, która poprawia obsługę ACL oraz wprowadzenie dodatkowych mechanizmów zabezpieczających, aby ograniczyć dostęp do systemu logowania.

Original NVD description (English source)
The ACL handling in rsyslog 3.12.1 to 3.20.0, 4.1.0, and 4.1.1 does not follow $AllowedSender directive, which allows remote attackers to bypass intended access restrictions and spoof log messages or create a large number of spurious messages.
