https://notcve.org/view.php?id=CVE-2021-1534
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. This vulnerability is due to improper processing 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 an affected device, which could allow malicious URLs to pass through the device. Una vulnerabilidad en los mecanismos de protección antispam del software Cisco AsyncOS para 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-sGcfsDrp • CWE-20: Improper Input Validation •

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.

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 •

https://notcve.org/view.php?id=CVE-2021-1129
A vulnerability in the authentication for the general purpose APIs implementation of Cisco Email Security Appliance (ESA), Cisco Content Security Management Appliance (SMA), and Cisco Web Security Appliance (WSA) could allow an unauthenticated, remote attacker to access general system information and certain configuration information from an affected device. The vulnerability exists because a secure authentication token is not required when authenticating to the general purpose API. An attacker could exploit this vulnerability by sending a crafted request for information to the general purpose API on an affected device. A successful exploit could allow the attacker to obtain system and configuration information from the affected device, resulting in an unauthorized information disclosure. Una vulnerabilidad en la autenticación para la implementación de las API de propósito general de Cisco Email Security Appliance (ESA), Cisco Content Security Management Appliance (SMA) y Cisco Web Security Appliance (WSA), podría permitir a un atacante no autenticado remoto acceder a información general del sistema y determinada información de configuración de un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-esa-wsa-sma-info-RHp44vAC • CWE-201: Insertion of Sensitive Information Into Sent Data •

https://notcve.org/view.php?id=CVE-2019-1947
A vulnerability in the email message filtering feature of Cisco AsyncOS Software for Cisco Email Security Appliance (ESA) could allow an unauthenticated, remote attacker to cause the CPU utilization to increase to 100 percent, causing a denial of service (DoS) condition on an affected device. The vulnerability is due to improper handling of email messages that contain large attachments. An attacker could exploit this vulnerability by sending a malicious email message through the targeted device. A successful exploit could allow the attacker to cause a permanent DoS condition due to high CPU utilization. This vulnerability may require manual intervention to recover the ESA. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20200219-esa-dos • CWE-20: Improper Input Validation •
