https://notcve.org/view.php?id=CVE-2022-20625
23 Feb 2022 — A vulnerability in the Cisco Discovery Protocol service of Cisco FXOS Software and Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to cause the service to restart, resulting in a denial of service (DoS) condition. This vulnerability is due to improper handling of Cisco Discovery Protocol messages that are processed by the Cisco Discovery Protocol service. An attacker could exploit this vulnerability by sending a series of malicious Cisco Discovery Protocol messages to an affected devi... • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-cdp-dos-G8DPLWYG • CWE-399: Resource Management Errors •

CVE-2020-10136 – IP-in-IP protocol allows a remote, unauthenticated attacker to route arbitrary network traffic
https://notcve.org/view.php?id=CVE-2020-10136
02 Jun 2020 — IP-in-IP protocol specifies IP Encapsulation within IP standard (RFC 2003, STD 1) that decapsulate and route IP-in-IP traffic is vulnerable to spoofing, access-control bypass and other unexpected behavior due to the lack of validation to verify network packets before decapsulation and routing. Múltiples productos que implementan la IP Encapsulation dentro del estándar IP (RFC 2003, STD 1) desencapsulan y enrutan el tráfico IP-in-IP sin ninguna comprobación, lo que podría permitir a un atacante remoto no aut... • https://github.com/PapayaJackal/ipeeyoupeewepee • CWE-290: Authentication Bypass by Spoofing •

CVE-2020-3172 – Cisco FXOS and NX-OS Software Cisco Discovery Protocol Arbitrary Code Execution and Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3172
26 Feb 2020 — A vulnerability in the Cisco Discovery Protocol feature of Cisco FXOS Software and Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to execute arbitrary code as root or cause a denial of service (DoS) condition on an affected device. The vulnerability exists because of insufficiently validated Cisco Discovery Protocol packet headers. An attacker could exploit this vulnerability by sending a crafted Cisco Discovery Protocol packet to a Layer 2-adjacent affected device. A successful expl... • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20200226-fxos-nxos-cdp • CWE-20: Improper Input Validation •

CVE-2020-3120 – Cisco FXOS, IOS XR, and NX-OS Software Cisco Discovery Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3120
05 Feb 2020 — A vulnerability in the Cisco Discovery Protocol implementation for Cisco FXOS Software, Cisco IOS XR Software, and Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to cause a reload of an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to a missing check when the affected software processes Cisco Discovery Protocol messages. An attacker could exploit this vulnerability by sending a malicious Cisco Discovery Protocol packet to an affected devi... • http://packetstormsecurity.com/files/156203/Cisco-Discovery-Protocol-CDP-Remote-Device-Takeover.html • CWE-190: Integer Overflow or Wraparound •

CVE-2019-1735 – Cisco NX-OS Software Command Injection Vulnerability (CVE-2019-1735)
https://notcve.org/view.php?id=CVE-2019-1735
15 May 2019 — A vulnerability in the CLI of Cisco NX-OS Software could allow an authenticated, local attacker to execute arbitrary commands with elevated privileges on the underlying operating system of an affected device. The vulnerability is due to insufficient validation of arguments passed to certain CLI commands. An attacker could exploit this vulnerability by including malicious input as the argument of an affected command. A successful exploit could allow the attacker to execute arbitrary commands on the underlyin... • http://www.securityfocus.com/bid/108365 • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') CWE-88: Improper Neutralization of Argument Delimiters in a Command ('Argument Injection') •
