CVE-2026-76445Multiple Cisco Products Snort 3 Denial of Service Vulnerability

Cisco Cisco Open Source Snort3; Cisco Cisco Secure Firewall Threat Defense (FTD) Software; Cisco Cisco UTD SNORT IPS Engine Software Publicada: (hace 19 días)

Descripción

Multiple Cisco products are affected by a vulnerability in the Snort 3 Detection Engine that could allow an unauthenticated, remote attacker to cause the detection engine to unexpectedly restart, resulting in a denial of service (DoS) condition. The vulnerability is due to a flaw in logic handling when General Packet Radio Service (GPRS) Tunneling Protocol (GTP) extension headers are processed within the codec. An attacker could exploit this vulnerability by sending a crafted, fragmented UDP datagram that contains these headers to the Snort 3 Detection Engine of an affected device. A successful exploit could allow the attacker to cause the detection engine to enter an infinite loop, resulting in a DoS condition.

Debilidad (CWE): CWE-835
