https://notcve.org/view.php?id=CVE-2020-3554
A vulnerability in the TCP packet processing of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to a memory exhaustion condition. An attacker could exploit this vulnerability by sending a high rate of crafted TCP traffic through an affected device. A successful exploit could allow the attacker to exhaust device resources, resulting in a DoS condition for traffic transiting the affected device. Una vulnerabilidad en el procesamiento de paquetes TCP de Cisco Adaptive Security Appliance (ASA) Software y Cisco Firepower Threat Defense (FTD) Software, podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio (DoS) en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asaftd-dos-QFcNEPfx • CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2020-3555
A vulnerability in the SIP inspection process of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a crash and reload of an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to a watchdog timeout and crash during the cleanup of threads that are associated with a SIP connection that is being deleted from the connection list. An attacker could exploit this vulnerability by sending a high rate of crafted SIP traffic through an affected device. A successful exploit could allow the attacker to cause a watchdog timeout and crash, resulting in a crash and reload of the affected device. Una vulnerabilidad en el proceso de inspección SIP de Cisco Adaptive Security Appliance (ASA) Software y Cisco Firepower Threat Defense (FTD) Software, podría permitir a un atacante remoto no autenticado causar un bloqueo y la recarga de un dispositivo afectado, resultando en una condición de denegación de servicio ( DoS). • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asaftd-sipdos-3DGvdjvg • CWE-404: Improper Resource Shutdown or Release •

https://notcve.org/view.php?id=CVE-2020-3557
A vulnerability in the host input API daemon of Cisco Firepower Management Center (FMC) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper certificate validation. An attacker could exploit this vulnerability by sending a crafted data stream to the host input daemon of the affected device. A successful exploit could allow the attacker to cause the host input daemon to restart. The attacker could use repeated attacks to cause the daemon to continuously reload, creating a DoS condition for the API. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-fmc-dos-3WymYWKh • CWE-295: Improper Certificate Validation •
CVSS: 6.1EPSS: 0%CPEs: 4EXPL: 0CVE-2020-3558 – Cisco Firepower Management Center Software Open Redirect Vulnerability
https://notcve.org/view.php?id=CVE-2020-3558
A vulnerability in the web-based management interface of Cisco Firepower Management Center (FMC) Software could allow an unauthenticated, remote attacker to redirect a user to a malicious web page. The vulnerability is due to improper input validation of the parameters of an HTTP request. An attacker could exploit this vulnerability by intercepting an HTTP request from a user. A successful exploit could allow the attacker to modify the HTTP request to cause the interface to redirect the user to a specific, malicious URL. This type of vulnerability is known as an open redirect attack and is used in phishing attacks that get users to unknowingly visit malicious sites. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-fmc-redirect-NYDuSEQn • CWE-601: URL Redirection to Untrusted Site ('Open Redirect') •

https://notcve.org/view.php?id=CVE-2020-3561
A vulnerability in the Clientless SSL VPN (WebVPN) of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to inject arbitrary HTTP headers in the responses of the affected system. The vulnerability is due to improper input sanitization. An attacker could exploit this vulnerability by persuading a user of the interface to click a crafted link. A successful exploit could allow the attacker to conduct a CRLF injection attack, adding arbitrary HTTP headers in the responses of the system and redirecting the user to arbitrary websites. Una vulnerabilidad en el Clientless SSL VPN (WebVPN) de Cisco Adaptive Security Appliance (ASA) Software y Cisco Firepower Threat Defense (FTD) Software, podría permitir a un atacante remoto no autenticado inyectar encabezados HTTP arbitrarios en las respuestas del sistema afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asa-ftd-crlf-inj-BX9uRwSn • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') CWE-93: Improper Neutralization of CRLF Sequences ('CRLF Injection') •
