https://notcve.org/view.php?id=CVE-2021-1431
A vulnerability in the vDaemon process of Cisco IOS XE SD-WAN Software could allow an unauthenticated, remote attacker to cause a device to reload, resulting a denial of service (DoS) condition. This vulnerability is due to insufficient handling of malformed packets. An attacker could exploit this vulnerability by sending crafted traffic to an affected device. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition. Una vulnerabilidad en el proceso vDaemon del Software Cisco IOS XE SD-WAN, podría permitir a un atacante remoto no autenticado causar la recarga de un dispositivo, lo que resultará en una condición de denegación de servicio (DoS). • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-sdwdos-4zeEeC9w • CWE-20: Improper Input Validation •
CVSS: 5.3EPSS: 0%CPEs: 23EXPL: 0CVE-2021-1236 – Multiple Cisco Products Snort Application Detection Engine Policy Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2021-1236
Multiple Cisco products are affected by a vulnerability in the Snort application detection engine that could allow an unauthenticated, remote attacker to bypass the configured policies on an affected system. The vulnerability is due to a flaw in the detection algorithm. An attacker could exploit this vulnerability by sending crafted packets that would flow through an affected system. A successful exploit could allow the attacker to bypass the configured policies and deliver a malicious payload to the protected network. Múltiples productos de Cisco están afectados por una vulnerabilidad en el motor de detección de aplicaciones de Snort que podría permitir a un atacante remoto no autenticado omitir las políticas configuradas en un sistema afectado. • https://lists.debian.org/debian-lts-announce/2023/02/msg00011.html https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-snort-app-bypass-cSBYCATq https://www.debian.org/security/2023/dsa-5354 • CWE-670: Always-Incorrect Control Flow Implementation •
CVSS: 5.8EPSS: 0%CPEs: 48EXPL: 0CVE-2021-1224 – Multiple Cisco Products Snort TCP Fast Open File Policy Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2021-1224
Multiple Cisco products are affected by a vulnerability with TCP Fast Open (TFO) when used in conjunction with the Snort detection engine that could allow an unauthenticated, remote attacker to bypass a configured file policy for HTTP. The vulnerability is due to incorrect detection of the HTTP payload if it is contained at least partially within the TFO connection handshake. An attacker could exploit this vulnerability by sending crafted TFO packets with an HTTP payload through an affected device. A successful exploit could allow the attacker to bypass configured file policy for HTTP packets and deliver a malicious payload.

CVSS: 7.5EPSS: 0%CPEs: 2EXPL: 0CVE-2020-3444 – Cisco SD-WAN Software Packet Filtering Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2020-3444
A vulnerability in the packet filtering features of Cisco SD-WAN Software could allow an unauthenticated, remote attacker to bypass L3 and L4 traffic filters. The vulnerability is due to improper traffic filtering conditions on an affected device. An attacker could exploit this vulnerability by crafting a malicious TCP packet with specific characteristics and sending it to a targeted device. A successful exploit could allow the attacker to bypass the L3 and L4 traffic filters and inject an arbitrary packet into the network. Una vulnerabilidad en la funcionalidad packet filtering de Cisco SD-WAN Software, podría permitir a un atacante remoto no autenticado omitir los filtros de tráfico L3 y L4. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-cedge-filt-bypass-Y6wZMqm4 • CWE-20: Improper Input Validation •
