CVE-2026-20125
HighSummary
Podatność w funkcji serwera HTTP oprogramowania Cisco IOS i Cisco IOS XE w wersji 3E może pozwolić uwierzytelnionemu, zdalnemu atakującemu na nieoczekiwane przeładowanie urządzenia, co prowadzi do stanu odmowy usługi (DoS). Problem wynika z niewłaściwej walidacji danych wejściowych dostarczonych przez użytkownika.
Risk Assessment
Organizacja może doświadczyć przerw w dostępności usług, co może prowadzić do zakłóceń w działalności oraz potencjalnych strat finansowych. Atakujący musi posiadać ważne konto użytkownika, aby móc wykorzystać tę podatność.
Recommendation
Zaleca się monitorowanie i ograniczenie dostępu do funkcji serwera HTTP oraz regularne aktualizowanie oprogramowania Cisco do najnowszych wersji, aby zminimalizować ryzyko wykorzystania tej podatności.

Original NVD description (English source)
A vulnerability in the HTTP Server feature of Cisco IOS Software and Cisco IOS XE Software Release 3E could allow an authenticated, remote attacker to cause an affected device to reload unexpectedly, resulting in a denial of service (DoS) condition. This vulnerability is due to improper validation of user-supplied input. An attacker could exploit this vulnerability by sending malformed HTTP requests to an affected device. A successful exploit could allow the attacker to cause a watchdog timer to expire and the device to reload, resulting in a DoS condition. To exploit this vulnerability, the attacker must have a valid user account.
