CVSS: 7.4EPSS: 0%CPEs: 12EXPL: 0CVE-2021-1566 – Cisco Email Security Appliance and Cisco Web Security Appliance Certificate Validation Vulnerability
https://notcve.org/view.php?id=CVE-2021-1566
A vulnerability in the Cisco Advanced Malware Protection (AMP) for Endpoints integration of Cisco AsyncOS for Cisco Email Security Appliance (ESA) and Cisco Web Security Appliance (WSA) could allow an unauthenticated, remote attacker to intercept traffic between an affected device and the AMP servers. This vulnerability is due to improper certificate validation when an affected device establishes TLS connections. A man-in-the-middle attacker could exploit this vulnerability by sending a crafted TLS packet to an affected device. A successful exploit could allow the attacker to spoof a trusted host and then extract sensitive information or alter certain API requests. Una vulnerabilidad en la integración de Cisco Advanced Malware Protection (AMP) for Endpoints de Cisco AsyncOS para Cisco Email Security Appliance (ESA) y Cisco Web Security Appliance (WSA) podría permitir a un atacante remoto no autenticado interceptar el tráfico entre un dispositivo afectado y los servidores AMP. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-esa-wsa-cert-vali-n8L97RW • CWE-295: Improper Certificate Validation CWE-296: Improper Following of a Certificate's Chain of Trust •

https://notcve.org/view.php?id=CVE-2021-1516
A vulnerability in the web-based management interface of Cisco AsyncOS Software for Cisco Content Security Management Appliance (SMA), Cisco Email Security Appliance (ESA), and Cisco Web Security Appliance (WSA) could allow an authenticated, remote attacker to access sensitive information on an affected device. The vulnerability exists because confidential information is included in HTTP requests that are exchanged between the user and the device. An attacker could exploit this vulnerability by looking at the raw HTTP requests that are sent to the interface. A successful exploit could allow the attacker to obtain some of the passwords that are configured throughout the interface. Una vulnerabilidad en la interfaz de administración basada en web de Cisco AsyncOS Software para Cisco Content Security Management Appliance (SMA), Cisco Email Security Appliance (ESA), y Cisco Web Security Appliance (WSA), podría permitir a un atacante remoto autenticado acceder a información confidencial. en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-esa-wsa-sma-info-gY2AEz2H • CWE-540: Inclusion of Sensitive Information in Source Code •
CVSS: 7.8EPSS: 0%CPEs: 4EXPL: 0CVE-2020-3367 – Cisco Secure Web Appliance Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2020-3367
A vulnerability in the log subscription subsystem of Cisco AsyncOS for the Cisco Secure Web Appliance (formerly Web Security Appliance) could allow an authenticated, local attacker to perform command injection and elevate privileges to root. This vulnerability is due to insufficient validation of user-supplied input for the web interface and CLI. An attacker could exploit this vulnerability by authenticating to the affected device and injecting scripting commands in the scope of the log subscription subsystem. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system and elevate privileges to root. Una vulnerabilidad en el subsistema de suscripción de registros de Cisco AsyncOS para Cisco Secure Web Appliance (anteriormente Web Security Appliance), podría permitir a un atacante local autenticado llevar a cabo la inyección de comandos y elevar los privilegios a root. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-wsa-prv-esc-nPzWZrQj • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
CVSS: 5.8EPSS: 0%CPEs: 1EXPL: 0CVE-2020-3568 – Cisco Email Security Appliance URL Filtering Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2020-3568
A vulnerability in the antispam protection mechanisms of Cisco AsyncOS Software for Cisco Email Security Appliance (ESA) could allow an unauthenticated, remote attacker to bypass the URL reputation filters on an affected device. The vulnerability is due to insufficient input validation of URLs. An attacker could exploit this vulnerability by crafting a URL in a particular way. A successful exploit could allow the attacker to bypass the URL reputation filters that are configured for the affected device, which could allow malicious URLs to pass through the device. Una vulnerabilidad en los mecanismos de protección antispam del Cisco AsyncOS Software for Cisco Email Security Appliance (ESA), podría permitir a un atacante remoto no autenticado omitir los filtros de reputación de URL en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-esa-url-bypass-zZtugtg3 • CWE-20: Improper Input Validation •
CVSS: 7.8EPSS: 0%CPEs: 7EXPL: 0CVE-2019-1983 – Cisco Email Security Appliance and Cisco Content Security Management Appliance Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1983
A vulnerability in the email message filtering feature of Cisco AsyncOS Software for Cisco Email Security Appliance (ESA) and Cisco Content Security Management Appliance (SMA) could allow an unauthenticated, remote attacker to cause repeated crashes in some internal processes that are running on the affected devices, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient input validation of email attachments. An attacker could exploit this vulnerability by sending an email message with a crafted attachment through an affected device. A successful exploit could allow the attacker to cause specific processes to crash repeatedly, resulting in the complete unavailability of both the Cisco Advanced Malware Protection (AMP) and message tracking features and in severe performance degradation while processing email. After the affected processes restart, the software resumes filtering for the same attachment, causing the affected processes to crash and restart again. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20200219-esa-sma-dos • CWE-20: Improper Input Validation •
