CVSS: 5.3EPSS: 0%CPEs: 6EXPL: 0CVE-2022-20675 – Multiple Cisco Security Products Simple Network Management Protocol Service Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2022-20675
A vulnerability in the TCP/IP stack of Cisco Email Security Appliance (ESA), Cisco Web Security Appliance (WSA), and Cisco Secure Email and Web Manager, formerly Security Management Appliance, could allow an unauthenticated, remote attacker to crash the Simple Network Management Protocol (SNMP) service, resulting in a denial of service (DoS) condition. This vulnerability is due to an open port listener on TCP port 199. An attacker could exploit this vulnerability by connecting to TCP port 199. A successful exploit could allow the attacker to crash the SNMP service, resulting in a DoS condition. Una vulnerabilidad en la pila TCP/IP de Cisco Email Security Appliance (ESA), Cisco Web Security Appliance (WSA) y Cisco Secure Email and Web Manager, anteriormente Security Management Appliance, podría permitir a un atacante remoto no autenticado bloquear el Servicio del Protocolo Simple de Administrador de Redes (SNMP), resultando en una situación de denegación de servicio (DoS). • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ESA-SNMP-JLAJksWK • CWE-248: Uncaught Exception •
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 •
CVSS: 8.6EPSS: 0%CPEs: 10EXPL: 0CVE-2021-34698 – Cisco Web Security Appliance Proxy Service Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2021-34698
A vulnerability in the proxy service of Cisco AsyncOS for Cisco Web Security Appliance (WSA) could allow an unauthenticated, remote attacker to exhaust system memory and cause a denial of service (DoS) condition on an affected device. This vulnerability is due to improper memory management in the proxy service of an affected device. An attacker could exploit this vulnerability by establishing a large number of HTTPS connections to the affected device. A successful exploit could allow the attacker to cause the system to stop processing new connections, which could result in a DoS condition. Note: Manual intervention may be required to recover from this situation. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-wsa-dos-fmHdKswk • CWE-401: Missing Release of Memory after Effective Lifetime •
