CVE-2019-25613
HighSummary
Easy Chat Server w wersji 3.1 zawiera podatność na atak typu denial of service, która pozwala zdalnym atakującym na zablokowanie aplikacji poprzez wysyłanie nadmiernie dużych danych w parametrze wiadomości. Atakujący mogą nawiązać sesję za pomocą punktu końcowego chat.ghp, a następnie wysłać żądanie POST do body2.ghp z nadmiernie dużą wartością parametru wiadomości, co powoduje awarię usługi.
Risk Assessment
Podatność ta może prowadzić do przerwy w dostępności usługi, co negatywnie wpłynie na użytkowników oraz może prowadzić do utraty zaufania do systemu. Organizacje mogą doświadczyć przestojów i związanych z tym strat finansowych.
Recommendation
Zaleca się aktualizację Easy Chat Server do najnowszej wersji, która eliminuje tę podatność. Dodatkowo warto wprowadzić ograniczenia dotyczące rozmiaru danych przesyłanych w wiadomościach.

Original NVD description (English source)
Easy Chat Server 3.1 contains a denial of service vulnerability that allows remote attackers to crash the application by sending oversized data in the message parameter. Attackers can establish a session via the chat.ghp endpoint and then send a POST request to body2.ghp with an excessively large message parameter value to cause the service to crash.
