CVSS: 8.6EPSS: 0%CPEs: 2EXPL: 0CVE-2019-1947 – Cisco Email Security Appliance Denial of Service Vulnerability
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 •
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: 7.5EPSS: 0%CPEs: 1EXPL: 0CVE-2020-3133 – Cisco Email Security Appliance Content Filter Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2020-3133
A vulnerability in the email message scanning of Cisco AsyncOS Software for Cisco Email Security Appliance (ESA) could allow an unauthenticated, remote attacker to bypass configured filters on the device. The vulnerability is due to improper validation of incoming emails. An attacker could exploit this vulnerability by sending a crafted email message to a recipient protected by the ESA. A successful exploit could allow the attacker to bypass the configured content filters, which could allow malicious content to pass through the device. Una vulnerabilidad en el escaneo de mensajes de correo electrónico de Cisco AsyncOS Software para Cisco Email Security Appliance (ESA), podría permitir a un atacante remoto no autenticado omitir los filtros configurados en el dispositivo. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-esa-bypass-5Cdv2HMA • CWE-20: Improper Input Validation •
CVSS: 6.1EPSS: 0%CPEs: 1EXPL: 0CVE-2020-3137 – Cisco Email Security Appliance Cross-Site Scripting Vulnerability
https://notcve.org/view.php?id=CVE-2020-3137
A vulnerability in the web-based management interface of Cisco Email Security Appliance (ESA) could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device. The vulnerability exists because the web-based management interface of the affected device does not properly validate user-supplied input. An attacker could exploit this vulnerability by persuading a user to click a malicious link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or to access sensitive, browser-based information. Una vulnerabilidad en la interfaz de administración basada en web de Cisco Email Security Appliance (ESA), podría permitir a un atacante remoto no autenticado conducir a ataques de tipo cross-site scripting (XSS) contra un usuario de la interfaz de administración basada en web de un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-email-sec-xss-EbjXuXwP • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
CVSS: 6.5EPSS: 0%CPEs: 2EXPL: 0CVE-2020-3447 – Cisco Email Security Appliance and Cisco Content Security Management Appliance Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2020-3447
A vulnerability in the CLI of Cisco AsyncOS for Cisco Email Security Appliance (ESA) and Cisco AsyncOS for Cisco Content Security Management Appliance (SMA) could allow an authenticated, remote attacker to access sensitive information on an affected device. The vulnerability is due to excessive verbosity in certain log subscriptions. An attacker could exploit this vulnerability by accessing specific log files on an affected device. A successful exploit could allow the attacker to obtain sensitive log data, which may include user credentials. To exploit this vulnerability, the attacker would need to have valid credentials at the operator level or higher on the affected device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-esa-sma-log-YxQ6g2kG • CWE-532: Insertion of Sensitive Information into Log File •
