https://notcve.org/view.php?id=CVE-2020-26082
A vulnerability in the zip decompression engine of Cisco AsyncOS Software for Cisco Email Security Appliance (ESA) could allow an unauthenticated, remote attacker to bypass content filters that are configured on an affected device. The vulnerability is due to improper handling of password-protected zip files. An attacker could exploit this vulnerability by sending a malicious file inside a crafted zip-compressed file to an affected device. A successful exploit could allow the attacker to bypass configured content filters that would normally drop the email. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-esa-zip-bypass-gbU4gtTg • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2022-20942
A vulnerability in the web-based management interface of Cisco Email Security Appliance (ESA), Cisco Secure Email and Web Manager, and Cisco Secure Web Appliance, formerly known as Cisco Web Security Appliance (WSA), could allow an authenticated, remote attacker to retrieve sensitive information from an affected device, including user credentials. This vulnerability is due to weak enforcement of back-end authorization checks. An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected device. A successful exploit could allow the attacker to obtain confidential data that is stored on the affected device. Una vulnerabilidad en la interfaz de administración basada en web de Cisco Email Security Appliance (ESA), Cisco Secure Email and Web Manager y Cisco Secure Web Appliance, anteriormente conocido como Cisco Web Security Appliance (WSA), podría permitir que un atacante remoto autenticado acceda a información sensible de un dispositivo afectado, incluidas las credenciales de usuario. Esta vulnerabilidad se debe a una aplicación débil de las comprobaciones de autorización del back-end. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-cnt-sec-infodiscl-BVKKnUG • CWE-359: Exposure of Private Personal Information to an Unauthorized Actor CWE-863: Incorrect Authorization •
CVSS: 5.4EPSS: 0%CPEs: 2EXPL: 0CVE-2022-20781 – Cisco Web Security Appliance Stored Cross-Site Scripting Vulnerability
https://notcve.org/view.php?id=CVE-2022-20781
A vulnerability in the web-based management interface of Cisco AsyncOS Software for Cisco Web Security Appliance (WSA) could allow an authenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against a user of the interface of an affected device. The vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by inserting malicious data into a specific data field in an affected interface. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface. Una vulnerabilidad en la interfaz de administración basada en web del software Cisco AsyncOS para Cisco Web Security Appliance (WSA) podría permitir a un atacante remoto autenticado conducir un ataque de tipo cross-site scripting (XSS) almacenado contra un usuario de la interfaz de un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-wsa-stored-xss-XPsJghMY • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
CVSS: 7.5EPSS: 0%CPEs: 3EXPL: 0CVE-2022-20653 – Cisco Email Security Appliance DNS Verification Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2022-20653
A vulnerability in the DNS-based Authentication of Named Entities (DANE) email verification component 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. This vulnerability is due to insufficient error handling in DNS name resolution by the affected software. An attacker could exploit this vulnerability by sending specially formatted email messages that are processed by an affected device. A successful exploit could allow the attacker to cause the device to become unreachable from management interfaces or to process additional email messages for a period of time until the device recovers, resulting in a DoS condition. Continued attacks could cause the device to become completely unavailable, resulting in a persistent DoS condition. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-esa-dos-MxZvGtgU • CWE-399: Resource Management Errors •
CVSS: 7.5EPSS: 0%CPEs: 14EXPL: 0CVE-2021-34741 – Cisco Email Security Appliance Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2021-34741
A vulnerability in the email scanning algorithm of Cisco AsyncOS software for Cisco Email Security Appliance (ESA) could allow an unauthenticated, remote attacker to perform a denial of service (DoS) attack against an affected device. This vulnerability is due to insufficient input validation of incoming emails. An attacker could exploit this vulnerability by sending a crafted email through Cisco ESA. A successful exploit could allow the attacker to exhaust all the available CPU resources on an affected device for an extended period of time, preventing other emails from being processed and resulting in a DoS condition. Una vulnerabilidad en el algoritmo de análisis del correo electrónico del software Cisco AsyncOS para Cisco Email Security Appliance (ESA) podría permitir a un atacante remoto no autenticado llevar a cabo un ataque de denegación de servicio (DoS) contra un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-esa-dos-JOm9ETfO • CWE-770: Allocation of Resources Without Limits or Throttling •
