Summary
HNB Organizer w wersji 1.9.18-10 zawiera lokalną podatność na przepełnienie bufora, która umożliwia lokalnym atakującym wykonanie dowolnego kodu poprzez dostarczenie zbyt dużego argumentu do parametru wiersza poleceń -rc. Atakujący mogą stworzyć złośliwy ciąg wejściowy przekraczający 108 bajtów, zawierający shellcode oraz adres powrotu, aby nadpisać stos i osiągnąć wykonanie kodu.
Risk Assessment
Podatność ta stwarza ryzyko dla organizacji, ponieważ umożliwia lokalnym atakującym przejęcie kontroli nad systemem poprzez wykonanie złośliwego kodu. Może to prowadzić do utraty danych, naruszenia integralności systemu oraz potencjalnych dalszych ataków.
Recommendation
Zaleca się aktualizację HNB Organizer do najnowszej wersji, która eliminuje tę podatność. Dodatkowo, należy ograniczyć dostęp do systemu tylko do zaufanych użytkowników oraz monitorować wszelkie podejrzane działania.

Original NVD description (English source)
HNB Organizer 1.9.18-10 contains a local buffer overflow vulnerability that allows local attackers to execute arbitrary code by supplying an oversized argument to the -rc command-line parameter. Attackers can craft a malicious input string exceeding 108 bytes containing shellcode and a return address to overwrite the stack and achieve code execution.
