Elasticsearch Remote Code Execution Vulnerability
Elastic - Elasticsearch · Listed in the CISA KEV since 2022-03-25. This indicates confirmed attacks in production environments.
Required action: Apply updates per vendor instructions.
CVE-2014-3120
HighCVSS 8.1KEVSummary
Domyślna konfiguracja w Elasticsearch przed wersją 1.2 umożliwia dynamiczne skrypty, co pozwala zdalnym atakującym na wykonywanie dowolnych wyrażeń MVEL i kodu Java za pomocą parametru source w zapytaniu _search. Problem ten występuje tylko, jeśli użytkownik nie uruchamia Elasticsearch w niezależnej maszynie wirtualnej.
Risk Assessment
Atakujący mogą wykorzystać tę podatność do zdalnego wykonywania kodu, co może prowadzić do poważnych naruszeń bezpieczeństwa i utraty danych w organizacji.
Recommendation
Zaleca się uruchamianie Elasticsearch w niezależnej maszynie wirtualnej oraz dezaktywację dynamicznego skryptowania, aby zminimalizować ryzyko związane z tą podatnością.

- CVE-2026-76949Critical
A vulnerability in the ash_authentication library (Elixir) allows an attacker who can plant a remember-me cookie in a victim's browser to replace the victim's authenticated session with one for the attacker's own account. The issue stems from a mismatch between the session keys used by the guard and the reader, causing remember-me sign-in to run on every request.
Original NVD description (English source)
The default configuration in Elasticsearch before 1.2 enables dynamic scripting, which allows remote attackers to execute arbitrary MVEL expressions and Java code via the source parameter to _search. NOTE: this only violates the vendor's intended security policy if the user does not run Elasticsearch in its own independent virtual machine.
