CVSS: 8.6EPSS: 0%CPEs: 60EXPL: 0CVE-2020-3203 – Cisco IOS XE Software Catalyst 9800 Series Wireless Controllers Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3203
A vulnerability in the locally significant certificate (LSC) provisioning feature of Cisco Catalyst 9800 Series Wireless Controllers that are running Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a memory leak that could lead to a denial of service (DoS) condition. The vulnerability is due to incorrect processing of certain public key infrastructure (PKI) packets. An attacker could exploit this vulnerability by sending crafted Secure Sockets Layer (SSL) packets to an affected device. A successful exploit could cause an affected device to continuously consume memory, which could result in a memory allocation failure that leads to a crash and causes a DoS condition. Una vulnerabilidad en la funcionalidad locally significant certificate (LSC) de Cisco Catalyst 9800 Series Wireless Controllers que ejecuta Cisco IOS XE Software, podría permitir a un atacante remoto no autenticado causar una pérdida de memoria que podría conllevar a una condición de denegación de servicio (DoS) . • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-ewlc-dos-TkuPVmZN • CWE-400: Uncontrolled Resource Consumption CWE-401: Missing Release of Memory after Effective Lifetime •
CVSS: 5.8EPSS: 0%CPEs: 23EXPL: 0CVE-2020-3315 – Multiple Cisco Products Snort HTTP Detection Engine File Policy Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2020-3315
Multiple Cisco products are affected by a vulnerability in the Snort detection engine that could allow an unauthenticated, remote attacker to bypass the configured file policies on an affected system. The vulnerability is due to errors in how the Snort detection engine handles specific HTTP responses. An attacker could exploit this vulnerability by sending crafted HTTP packets that would flow through an affected system. A successful exploit could allow the attacker to bypass the configured file policies and deliver a malicious payload to the protected network. Múltiples productos de Cisco están afectados por una vulnerabilidad en el motor de detección Snort que podría permitir a un atacante remoto no autenticado omitir las políticas de archivos configuradas sobre 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_filepolbypass-m4X5DgOP https://www.debian.org/security/2023/dsa-5354 • CWE-668: Exposure of Resource to Wrong Sphere CWE-693: Protection Mechanism Failure •

https://notcve.org/view.php?id=CVE-2019-12669
A vulnerability in the RADIUS Change of Authorization (CoA) code of Cisco TrustSec, a feature within Cisco IOS XE Software, could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper handling of a malformed packet. An attacker could exploit this vulnerability by sending a malformed packet to an affected device. A successful exploit could allow the attacker to cause a DoS condition on the affected device.

CVSS: 7.4EPSS: 0%CPEs: 2EXPL: 0CVE-2019-12665 – Cisco IOS and IOS XE Software HTTP Client Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2019-12665
A vulnerability in the HTTP client feature of Cisco IOS and IOS XE Software could allow an unauthenticated, remote attacker to read and modify data that should normally have been sent via an encrypted channel. The vulnerability is due to TCP port information not being considered when matching new requests to existing, persistent HTTP connections. An attacker could exploit this vulnerability by acting as a man-in-the-middle and then reading and/or modifying data that should normally have been sent through an encrypted channel. Una vulnerabilidad en la funcionalidad HTTP client de los Software Cisco IOS y IOS XE, podría permitir a un atacante remoto no autenticado leer y modificar datos que normalmente deberían haber sido enviados por medio de un canal encriptado. La vulnerabilidad es debido a que no ha sido considerada la información del puerto TCP al hacer coincidir nuevas peticiones con conexiones HTTP persistentes y existentes. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190925-http-client • CWE-399: Resource Management Errors •
CVSS: 8.6EPSS: 0%CPEs: 6EXPL: 0CVE-2019-12655 – Cisco IOS XE Software FTP Application Layer Gateway for NAT, NAT64, and ZBFW Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-12655
A vulnerability in the FTP application layer gateway (ALG) functionality used by Network Address Translation (NAT), NAT IPv6 to IPv4 (NAT64), and the Zone-Based Policy Firewall (ZBFW) in Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload. The vulnerability is due to a buffer overflow that occurs when an affected device inspects certain FTP traffic. An attacker could exploit this vulnerability by performing a specific FTP transfer through the device. A successful exploit could allow the attacker to cause the device to reload. Una vulnerabilidad en la funcionalidad application layer gateway (ALG) de FTP, utilizada por Network Address Translation (NAT), NAT IPv6 a IPv4 (NAT64) y el Zone-Based Policy Firewall (ZBFW) en Software Cisco IOS XE, podría permitir a un atacante remoto no autenticado causar que un dispositivo afectado se recargue. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190925-ftp • CWE-20: Improper Input Validation CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
