CVE-2024-11857
HighSummary
Adapter Bluetooth HCI od Realtek ma podatność związaną z śledzeniem linków. Lokalni atakujący z normalnymi uprawnieniami mogą stworzyć symboliczny link o tej samej nazwie co określony plik, co prowadzi do usunięcia dowolnych plików wskazywanych przez ten link.
Risk Assessment
Atakujący mogą wykorzystać usunięcie plików do eskalacji uprawnień, co stwarza poważne zagrożenie dla bezpieczeństwa systemu. Może to prowadzić do nieautoryzowanego dostępu do wrażliwych danych lub funkcji systemowych.
Recommendation
Zaleca się monitorowanie i ograniczenie możliwości tworzenia symbolicznych linków przez użytkowników oraz aktualizację oprogramowania adaptera Bluetooth HCI w celu usunięcia tej podatności.

Original NVD description (English source)
Bluetooth HCI Adaptor from Realtek has a Link Following vulnerability. Local attackers with regular privileges can create a symbolic link with the same name as a specific file, causing the product to delete arbitrary files pointed to by the link. Subsequently, attackers can leverage arbitrary file deletion to privilege escalation.
