CVSS: 7.4EPSS: 0%CPEs: 9EXPL: 0CVE-2022-20742 – Cisco Adaptive Security Appliance Software and Firepower Threat Defense Software IPsec IKEv2 VPN Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2022-20742
A vulnerability in an IPsec VPN library of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to read or modify data within an IPsec IKEv2 VPN tunnel. This vulnerability is due to an improper implementation of Galois/Counter Mode (GCM) ciphers. An attacker in a man-in-the-middle position could exploit this vulnerability by intercepting a sufficient number of encrypted messages across an affected IPsec IKEv2 VPN tunnel and then using cryptanalytic techniques to break the encryption. A successful exploit could allow the attacker to decrypt, read, modify, and re-encrypt data that is transmitted across an affected IPsec IKEv2 VPN tunnel. Una vulnerabilidad en una biblioteca de VPN IPsec del software Cisco Adaptive Security Appliance (ASA) y del software Cisco Firepower Threat Defense (FTD) podría permitir a un atacante remoto no autenticado leer o modificar datos dentro de un túnel VPN IPsec IKEv2. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asaftd-ipsec-mitm-CKnLr4 • CWE-325: Missing Cryptographic Step •
CVSS: 8.8EPSS: 0%CPEs: 9EXPL: 1CVE-2022-20759 – Cisco Adaptive Security Appliance Software and Firepower Threat Defense Software Web Services Interface Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2022-20759
A vulnerability in the web services interface for remote access VPN features of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, but unprivileged, remote attacker to elevate privileges to level 15. This vulnerability is due to improper separation of authentication and authorization scopes. An attacker could exploit this vulnerability by sending crafted HTTPS messages to the web services interface of an affected device. A successful exploit could allow the attacker to gain privilege level 15 access to the web management interface of the device. This includes privilege level 15 access to the device using management tools like the Cisco Adaptive Security Device Manager (ASDM) or the Cisco Security Manager (CSM). • https://github.com/orangecertcc/security-research/security/advisories/GHSA-gq88-gqmj-7v24 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asaftd-mgmt-privesc-BMFMUvye • CWE-266: Incorrect Privilege Assignment CWE-269: Improper Privilege Management •
CVSS: 8.6EPSS: 0%CPEs: 9EXPL: 0CVE-2022-20760 – Cisco Adaptive Security Appliance Software and Firepower Threat Defense Software DNS Inspection Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2022-20760
A vulnerability in the DNS inspection handler of Cisco Adaptive Security Appliance (ASA) Software and Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a denial of service condition (DoS) on an affected device. This vulnerability is due to a lack of proper processing of incoming requests. An attacker could exploit this vulnerability by sending crafted DNS requests at a high rate to an affected device. A successful exploit could allow the attacker to cause the device to stop responding, resulting in a DoS condition. Una vulnerabilidad en el controlador de inspección de DNS del software Cisco Adaptive Security Appliance (ASA) y del software Firepower Threat Defense (FTD) 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-nJVAwOeq • CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2022-20745
A vulnerability in the web services interface for remote access VPN features 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. This vulnerability is due to improper input validation when parsing HTTPS requests. An attacker could exploit this vulnerability by sending a crafted HTTPS request to an affected device. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition.

CVSS: 7.5EPSS: 0%CPEs: 30EXPL: 0CVE-2022-20795 – Cisco Adaptive Security Appliance and Cisco Firepower Threat Defense Software AnyConnect SSL VPN Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2022-20795
A vulnerability in the implementation of the Datagram TLS (DTLS) protocol in Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause high CPU utilization, resulting in a denial of service (DoS) condition. This vulnerability is due to suboptimal processing that occurs when establishing a DTLS tunnel as part of an AnyConnect SSL VPN connection. An attacker could exploit this vulnerability by sending a steady stream of crafted DTLS traffic to an affected device. A successful exploit could allow the attacker to exhaust resources on the affected VPN headend device. This could cause existing DTLS tunnels to stop passing traffic and prevent new DTLS tunnels from establishing, resulting in a DoS condition. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-vpndtls-dos-TunzLEV • CWE-345: Insufficient Verification of Data Authenticity •
