CVE-2020-36941
CriticalSummary
Knockpy w wersji 4.1.1 zawiera podatność na wstrzykiwanie CSV, która pozwala atakującym na wstrzykiwanie złośliwych formuł do raportów CSV poprzez nieprzefiltrowane nagłówki serwera. Atakujący mogą manipulować nagłówkami odpowiedzi serwera, aby zawierały formuły arkusza kalkulacyjnego, które zostaną wykonane po otwarciu CSV w aplikacjach arkuszy kalkulacyjnych.
Risk Assessment
Podatność ta stwarza ryzyko wykonania złośliwego kodu w aplikacjach arkuszy kalkulacyjnych, co może prowadzić do utraty danych lub kompromitacji systemów użytkowników. Organizacje mogą być narażone na ataki phishingowe i inne formy oszustw.
Recommendation
Zaleca się filtrowanie i walidację nagłówków serwera, aby zapobiec wstrzykiwaniu złośliwych formuł. Należy również edukować użytkowników na temat potencjalnych zagrożeń związanych z otwieraniem plików CSV z nieznanych źródeł.
