CVE-2020-37012
CriticalSummary
Tea LaTex 1.0 zawiera podatność na zdalne wykonanie kodu, która pozwala nieautoryzowanym atakującym na wykonywanie dowolnych poleceń powłoki przez punkt końcowy /api.php. Atakujący mogą stworzyć złośliwy ładunek LaTeX z poleceniami powłoki, które są wykonywane podczas przetwarzania przez akcję API tex2png aplikacji.
Risk Assessment
Podatność ta stwarza poważne ryzyko dla organizacji, umożliwiając atakującym zdalne wykonywanie kodu, co może prowadzić do przejęcia kontroli nad systemem. Niekontrolowane wykonanie poleceń powłoki może skutkować utratą danych lub naruszeniem bezpieczeństwa.
Recommendation
Zaleca się natychmiastowe zaktualizowanie aplikacji Tea LaTex do najnowszej wersji, która eliminuje tę podatność. Dodatkowo, warto ograniczyć dostęp do punktu końcowego /api.php tylko do zaufanych użytkowników.
