CVE-2020-14145
LowSummary
W kliencie OpenSSH w wersjach od 5.7 do 8.4 występuje zauważalna niezgodność prowadząca do wycieku informacji podczas negocjacji algorytmów. Umożliwia to atakującym typu man-in-the-middle atakowanie początkowych prób połączenia, gdy klient nie ma zapisanych kluczy hosta serwera.
Risk Assessment
Organizacje mogą być narażone na ataki man-in-the-middle, co może prowadzić do ujawnienia wrażliwych informacji podczas nawiązywania połączeń. To zwiększa ryzyko przechwycenia danych przez nieautoryzowane osoby.
Recommendation
Zaleca się aktualizację OpenSSH do najnowszej wersji, aby zniwelować ryzyko związane z tą podatnością. Dodatkowo, warto rozważyć implementację dodatkowych środków zabezpieczających, takich jak weryfikacja kluczy hosta.

Original NVD description (English source)
The client side in OpenSSH 5.7 through 8.4 has an Observable Discrepancy leading to an information leak in the algorithm negotiation. This allows man-in-the-middle attackers to target initial connection attempts (where no host key for the server has been cached by the client). NOTE: some reports sta
