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 •
CVSS: 6.5EPSS: 0%CPEs: 6EXPL: 0CVE-2020-3547 – Cisco Email Security Appliance, Cisco Content Security Management Appliance, and Cisco Web Security Appliance Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2020-3547
A vulnerability in the web-based management interface of Cisco AsyncOS software for Cisco Email Security Appliance (ESA), Cisco Content Security Management Appliance (SMA), and Cisco Web Security Appliance (WSA) could allow an authenticated, remote attacker to access sensitive information on an affected device. The vulnerability exists because an insecure method is used to mask certain passwords on the web-based management interface. An attacker could exploit this vulnerability by looking at the raw HTML code that is received from the interface. A successful exploit could allow the attacker to obtain some of the passwords configured throughout the interface. Una vulnerabilidad en la interfaz de administración basada en web en el software Cisco AsyncOS para Cisco Email Security Appliance (ESA), Cisco Content Security Management Appliance (SMA) 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-sma-wsa-esa-info-dis-vsvPzOHP • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-522: Insufficiently Protected Credentials •

https://notcve.org/view.php?id=CVE-2020-3546
A vulnerability in the web-based management interface of Cisco AsyncOS software for Cisco Email Security Appliance (ESA) could allow an unauthenticated, remote attacker to access sensitive information on an affected device. The vulnerability is due to insufficient validation of requests that are sent to the web-based management interface. An attacker could exploit this vulnerability by sending a crafted request to the interface of an affected device. A successful exploit could allow the attacker to obtain the IP addresses that are configured on the internal interfaces of the affected device. There is a workaround that addresses this vulnerability. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-esa-info-disclosure-vMJMMgJ • CWE-20: Improper Input Validation •
CVSS: 5.8EPSS: 0%CPEs: 2EXPL: 0CVE-2020-3368 – Cisco Email Security Appliance URL Filtering Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2020-3368
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 the 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 de Cisco AsyncOS Software para Cisco Email Security Appliance (ESA), podría permitir a un atacante remoto no autenticado omitir los filtros de reputación de URL sobre un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-esa-url-bypass-WO4BZ75s • CWE-20: Improper Input Validation •
CVSS: 8.6EPSS: 0%CPEs: 3EXPL: 0CVE-2018-15460 – Cisco Email Security Appliance URL Filtering Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-15460
A vulnerability in the email message filtering feature of Cisco AsyncOS Software for Cisco Email Security Appliances (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 filtering of email messages that contain references to whitelisted URLs. An attacker could exploit this vulnerability by sending a malicious email message that contains a large number of whitelisted URLs. A successful exploit could allow the attacker to cause a sustained DoS condition that could force the affected device to stop scanning and forwarding email messages. Una vulnerabilidad en la funcionalidad de filtrado de mensajes de correo electrónico de Cisco AsyncOS Software para Cisco Email Security Appliances (ESA) podría permitir que un atacante remoto no autenticado aumente el uso de la CPU hasta el 100 por ciento, provocando una condición de denegación de servicio (DoS) en un dispositivo afectado. • http://www.securityfocus.com/bid/106507 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190109-esa-url-dos • CWE-20: Improper Input Validation CWE-770: Allocation of Resources Without Limits or Throttling •
