CVE-2012-6436
HighCVSS 7.5Summary
Urządzenie nieprawidłowo weryfikuje dane wysyłane do bufora. Atakujący może wysłać źle sformatowany pakiet CIP do portów 2222/TCP, 2222/UDP, 44818/TCP lub 44818/UDP, co prowadzi do przepełnienia bufora i awarii CPU.
Risk Assessment
Skuteczne wykorzystanie tej podatności może prowadzić do utraty dostępności oraz zakłócenia komunikacji z innymi podłączonymi urządzeniami, co może wpłynąć na operacje organizacji.
Recommendation
Zaleca się aktualizację oprogramowania urządzeń oraz wdrożenie odpowiednich mechanizmów zabezpieczających, aby zminimalizować ryzyko ataków wykorzystujących tę podatność.

Original NVD description (English source)
The device does not properly validate the data being sent to the buffer. An attacker can send a malformed CIP packet to Port 2222/TCP, Port 2222/UDP, Port 44818/TCP, or Port 44818/UDP, which creates a buffer overflow and causes the CPU to crash. Successful exploitation of this vulnerability could cause loss of availability and a disruption in communications with other connected devices.
