CVE-2026-31851
CriticalSummary
Oprogramowanie układowe Nexxt Solutions Nebula 300+ w wersjach do 12.01.01.37 nie wprowadza ograniczeń liczby prób logowania ani mechanizmów blokady kont na interfejsach uwierzytelniania. Atakujący może przeprowadzać nieograniczone próby uwierzytelnienia, co umożliwia ataki typu brute-force na dane logowania administratora.
Risk Assessment
Brak ograniczeń w próbach logowania stwarza poważne ryzyko dla bezpieczeństwa, umożliwiając atakującym łatwe zgadywanie danych logowania administratorów. Może to prowadzić do nieautoryzowanego dostępu do systemu i potencjalnych strat dla organizacji.
Recommendation
Zaleca się aktualizację oprogramowania układowego do najnowszej wersji, która wprowadza mechanizmy ograniczające próby logowania oraz blokady kont. Dodatkowo warto wdrożyć dodatkowe środki zabezpieczające, takie jak monitorowanie prób logowania i stosowanie silnych haseł.

- CVE-2026-7826Critical
A vulnerability in FalkorDB before 4.18.4 causes a heap-based out-of-bounds read in the BufferSerializerIOv2_ReadBuffer function. A remote attacker who can issue Redis replication commands (e.g., against an instance with no password) can send a crafted RDB stream with a sub-buffer length field exceeding the remaining buffer size. The only bounds check is an ASSERT(), which is compiled out in release builds, so memcpy() reads past the end of the heap allocation.
- CVE-2026-5759Critical
A double free and use-after-free vulnerability in the RdbLoadDeletedNodes function of the RDB graph decoders in FalkorDB before 4.18.1. A remote attacker who can issue Redis replication commands can send a crafted RDB stream where the deleted-nodes buffer length is not a multiple of sizeof(NodeID). The length check relies on ASSERT(), which is compiled out in release builds, so the function continues after freeing the buffer, reading it and freeing it a second time.

Original NVD description (English source)
Nexxt Solutions Nebula 300+ firmware through version 12.01.01.37 does not implement rate limiting or account lockout mechanisms on authentication interfaces. An attacker can perform unlimited authentication attempts against endpoints that rely on credential validation, enabling brute-force attacks to guess administrative credentials without restriction.
