CVE-2026-7136
CriticalSummary
Zidentyfikowano słabość w urządzeniu Totolink A8000RU w wersji 7.1cu.643_b20200521. Problem dotyczy funkcji setDmzCfg w pliku /cgi-bin/cstecgi.cgi komponentu CGI Handler, gdzie manipulacja argumentem wanIdx może prowadzić do wstrzyknięcia poleceń systemowych.
Risk Assessment
Atakujący może zdalnie wykorzystać tę podatność do wykonania nieautoryzowanych poleceń na urządzeniu, co stwarza poważne zagrożenie dla bezpieczeństwa sieci organizacji.
Recommendation
Zaleca się aktualizację oprogramowania urządzenia do najnowszej wersji, która eliminuje tę podatność oraz monitorowanie ruchu sieciowego w celu wykrycia potencjalnych prób ataków.

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.
