CVSS: 5.3EPSS: 0%CPEs: 4EXPL: 0CVE-2020-3164 – Cisco ESA, Cisco WSA, and Cisco SMA GUI Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3164
A vulnerability in the web-based management interface of Cisco AsyncOS for Cisco Email Security Appliance (ESA), Cisco Web Security Appliance (WSA), and Cisco Content Security Management Appliance (SMA) could allow an unauthenticated remote attacker to cause high CPU usage on an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to improper validation of specific HTTP request headers. An attacker could exploit this vulnerability by sending a malformed HTTP request to an affected device. A successful exploit could allow the attacker to trigger a prolonged status of high CPU utilization relative to the GUI process(es). Upon successful exploitation of this vulnerability, an affected device will still be operative, but its response time and overall performance may be degraded. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-cont-sec-gui-dos-nJ625dXb • CWE-20: Improper Input Validation •
CVSS: 6.5EPSS: 0%CPEs: 1EXPL: 0CVE-2020-3181 – Cisco Email Security Appliance Uncontrolled Resource Exhaustion Vulnerability
https://notcve.org/view.php?id=CVE-2020-3181
A vulnerability in the malware detection functionality in Cisco Advanced Malware Protection (AMP) in Cisco AsyncOS Software for Cisco Email Security Appliances (ESAs) could allow an unauthenticated remote attacker to exhaust resources on an affected device. The vulnerability is due to insufficient control over system memory allocation. An attacker could exploit this vulnerability by sending a crafted email through the targeted device. A successful exploit could allow the attacker to cause an email attachment that contains malware to be delivered to a user and cause email processing delays. Una vulnerabilidad en la funcionalidad de detección de malware en Cisco Advanced Malware Protection (AMP) en Cisco AsyncOS Software para Cisco Email Security Appliances (ESAs), podría permitir a un atacante remoto no autenticado agotar los recursos en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-esa-resource-exhaust-D7RQAhnD • CWE-400: Uncontrolled Resource Consumption •
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: 5.3EPSS: 0%CPEs: 1EXPL: 0CVE-2019-1844 – Cisco Email Security Appliance Filter Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2019-1844
A vulnerability in certain attachment detection mechanisms of the Cisco Email Security Appliance (ESA) could allow an unauthenticated, remote attacker to bypass the filtering functionality of an affected device. The vulnerability is due to improper detection of certain content sent to an affected device. An attacker could exploit this vulnerability by sending certain file types without Content-Disposition information to an affected device. A successful exploit could allow an attacker to send messages that contain malicious content to users. Una vulnerabilidad en ciertos mecanismos de detección de adjuntos de Cisco Email Security Appliance (ESA) podrían permitir a un atacante remoto, no autenticado saltarse la funcionalidad de filtrado en un dispositivo afectado. • http://www.securityfocus.com/bid/108149 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190501-esa-bypass • CWE-20: Improper Input Validation •
