CVE-2021-34714 – Multiple Cisco Operating Systems Unidirectional Link Detection Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2021-34714
A vulnerability in the Unidirectional Link Detection (UDLD) feature of Cisco FXOS Software, Cisco IOS Software, Cisco IOS XE Software, Cisco IOS XR Software, and Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to cause an affected device to reload. This vulnerability is due to improper input validation of the UDLD packets. An attacker could exploit this vulnerability by sending specifically crafted UDLD packets to an affected device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a denial of service (DoS) condition. Note: The UDLD feature is disabled by default, and the conditions to exploit this vulnerability are strict. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ios-nxos-xr-udld-dos-W5hGHgtQ • CWE-20: Improper Input Validation •
CVE-2019-12699 – Cisco FXOS Software and Firepower Threat Defense Software Command Injection Vulnerabilities
https://notcve.org/view.php?id=CVE-2019-12699
Multiple vulnerabilities in the CLI of Cisco FXOS Software and Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, local attacker to execute commands on the underlying operating system (OS) with root privileges. These vulnerabilities are due to insufficient input validation. An attacker could exploit these vulnerabilities by including crafted arguments to specific CLI commands. A successful exploit could allow the attacker to execute commands on the underlying OS with root privileges.

CVE-2019-1714 – Cisco Adaptive Security Appliance Software and Firepower Threat Defense Software VPN SAML Authentication Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2019-1714
A vulnerability in the implementation of Security Assertion Markup Language (SAML) 2.0 Single Sign-On (SSO) for Clientless SSL VPN (WebVPN) and AnyConnect Remote Access VPN in Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to successfully establish a VPN session to an affected device. The vulnerability is due to improper credential management when using NT LAN Manager (NTLM) or basic authentication. An attacker could exploit this vulnerability by opening a VPN session to an affected device after another VPN user has successfully authenticated to the affected device via SAML SSO. A successful exploit could allow the attacker to connect to secured networks behind the affected device. Una vulnerabilidad en la implementación del Security Assertion Markup Language (SAML) versión 2.0 Single Sign-On (SSO) para VPN SSL sin clientes (WebVPN) y AnyConnect Remote Access VPN en Cisco Adaptive Security Appliance (ASA) Programa y Cisco Firepower Threat Defense (FTD) El programa podría permitir a un atacante remoto no autenticado establecer con éxito una sesión VPN en un dispositivo afectado. • http://www.securityfocus.com/bid/108185 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190501-asaftd-saml-vpn • CWE-255: Credentials Management Errors •
CVE-2019-1611 – Cisco FXOS and NX-OS Software CLI Command Injection Vulnerability (CVE-2019-1611)
https://notcve.org/view.php?id=CVE-2019-1611
A vulnerability in the CLI of Cisco NX-OS Software and Cisco FXOS Software could allow an authenticated, local attacker to execute arbitrary commands 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 underlying operating system with elevated privileges. An attacker would need valid administrator credentials to exploit this vulnerability. • http://www.securityfocus.com/bid/107381 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190306-nxos-cmdinj-1611 • 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') •
CVE-2019-1600 – Cisco FXOS and NX-OS Software Unauthorized Directory Access Vulnerability
https://notcve.org/view.php?id=CVE-2019-1600
A vulnerability in the file system permissions of Cisco FXOS Software and Cisco NX-OS Software could allow an authenticated, local attacker to access sensitive information that is stored in the file system of an affected system. The vulnerability is due to improper implementation of file system permissions. An attacker could exploit this vulnerability by accessing and modifying restricted files. A successful exploit could allow the attacker to access sensitive and critical files. Firepower 4100 Series Next-Generation Firewalls are affected in versions prior to 2.2.2.91 and 2.3.1.110. • http://www.securityfocus.com/bid/107399 http://www.securityfocus.com/bid/107404 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190306-nxos-directory • CWE-264: Permissions, Privileges, and Access Controls CWE-732: Incorrect Permission Assignment for Critical Resource •
