CVSS: 7.1EPSS: 0%CPEs: 4EXPL: 0CVE-2020-3132 – Cisco Email Security Appliance Shortened URL Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3132
A vulnerability in the email message scanning feature of Cisco AsyncOS Software for Cisco Email Security Appliance (ESA) could allow an unauthenticated, remote attacker to cause a temporary denial of service (DoS) condition on an affected device. The vulnerability is due to inadequate parsing mechanisms for specific email body components. An attacker could exploit this vulnerability by sending a malicious email containing a high number of shortened URLs through an affected device. A successful exploit could allow the attacker to consume processing resources, causing a DoS condition on an affected device. To successfully exploit this vulnerability, certain conditions beyond the control of the attacker must occur. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-esa-shrt-dos-wM54R8qA • CWE-400: Uncontrolled Resource Consumption •
CVSS: 6.5EPSS: 0%CPEs: 1EXPL: 0CVE-2020-3134 – Cisco Email Security Appliance Zip Decompression Engine Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3134
A vulnerability in the zip decompression engine of Cisco AsyncOS Software for Cisco Email Security Appliance (ESA) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper validation of zip files. An attacker could exploit this vulnerability by sending an email message with a crafted zip-compressed attachment. A successful exploit could trigger a restart of the content-scanning process, causing a temporary DoS condition. This vulnerability affects Cisco AsyncOS Software for Cisco ESA releases earlier than 13.0. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-esa-dos-87mBkc8n • CWE-20: Improper Input Validation •
CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 0CVE-2019-1921 – Cisco Email Security Appliance Content Filter Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2019-1921
A vulnerability in the attachment scanning of Cisco AsyncOS Software for Cisco Email Security Appliance (ESA) could allow an unauthenticated, remote attacker to bypass configured content filters on the device. The vulnerability is due to improper input validation of the email body. An attacker could exploit this vulnerability by naming a malicious attachment with a specific pattern. A successful exploit could allow the attacker to bypass configured content filters that would normally block the attachment. Una vulnerabilidad en el escaneo de archivos adjuntos del software AsyncOS de Cisco para Email Security Appliance (ESA) de Cisco, podría permitir a un atacante remoto no identificado omitir los filtros de contenido configurados en el dispositivo. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190703-esa-bypass • CWE-20: Improper Input Validation •
