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. Múltiples productos de Cisco están afectados por una vulnerabilidad con TCP Fast Open (TFO) cuando se usan en conjunto con el motor de detección Snort que podría permitir a un atacante remoto no autenticado omitir una política de archivos configurada para HTTP. • https://lists.debian.org/debian-lts-announce/2023/02/msg00011.html https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-snort-tfo-bypass-MmzZrtes https://www.debian.org/security/2023/dsa-5354 • CWE-693: Protection Mechanism Failure •

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 •

https://notcve.org/view.php?id=CVE-2020-3516
A vulnerability in the web server authentication of Cisco IOS XE Software could allow an authenticated, remote attacker to crash the web server on the device. The vulnerability is due to insufficient input validation during authentication. An attacker could exploit this vulnerability by entering unexpected characters during a valid authentication. A successful exploit could allow the attacker to crash the web server on the device, which must be manually recovered by disabling and re-enabling the web server. Una vulnerabilidad en la autenticación del servidor web de Cisco IOS XE Software, podría permitir a un atacante remoto autenticado bloquear el servidor web en el dispositivo. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-WEB-UI-exNFmcPO • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2019-16009
A vulnerability in the web UI of Cisco IOS and Cisco IOS XE Software could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack on an affected system. The vulnerability is due to insufficient CSRF protections for the web UI on an affected device. An attacker could exploit this vulnerability by persuading a user of the interface to follow a malicious link. A successful exploit could allow the attacker to perform arbitrary actions with the privilege level of the targeted user. If the user has administrative privileges, the attacker could alter the configuration, execute commands, or reload an affected device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20200108-ios-csrf • CWE-352: Cross-Site Request Forgery (CSRF) •
