CVE-2025-20192
HighCVSS 7.7Summary
Podatność w implementacji protokołu IKEv1 w oprogramowaniu Cisco IOS XE może umożliwić uwierzytelnionemu, zdalnemu atakującemu spowodowanie warunków odmowy usługi (DoS). Atakujący musi posiadać ważne poświadczenia VPN IKEv1, aby wykorzystać tę podatność.
Risk Assessment
Ryzyko dla organizacji polega na możliwości zdalnego wywołania ponownego uruchomienia urządzenia, co może prowadzić do przerw w dostępności usług sieciowych.
Recommendation
Zaleca się aktualizację oprogramowania Cisco IOS XE do najnowszej wersji, aby usunąć tę podatność oraz monitorowanie logów w celu wykrycia potencjalnych prób ataków.

Original NVD description (English source)
A vulnerability in the Internet Key Exchange version 1 (IKEv1) implementation of Cisco IOS XE Software could allow an authenticated, remote attacker to cause a denial of service (DoS) condition. The attacker must have valid IKEv1 VPN credentials to exploit this vulnerability. This vulnerability is due to improper validation of IKEv1 phase 2 parameters before the IPsec security association creation request is handed off to the hardware cryptographic accelerator of an affected device. An attacker could exploit this vulnerability by sending crafted IKEv1 messages to the affected device. A successful exploit could allow the attacker to cause the device to reload.
