CVSS: 8.6EPSS: 0%CPEs: 80EXPL: 0CVE-2024-20339 – Cisco Firepower Threat Defense Software for Firepower 2100 Series TLS Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2024-20339
A vulnerability in the TLS processing feature of Cisco Firepower Threat Defense (FTD) Software for Cisco Firepower 2100 Series could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to an issue that occurs when TLS traffic is processed. An attacker could exploit this vulnerability by sending certain TLS traffic over IPv4 through an affected device. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition and impacting traffic to and through the affected device. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-tls-dos-QXYE5Ufy https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-fmc-xss-M446vbEO https://sec.cloudapps.cisco.com/security/center/viewErp.x?alertId=ERP-75300 •
CVSS: 6.8EPSS: 0%CPEs: 272EXPL: 0CVE-2024-20331 – Cisco Adaptive Security Appliance and Firepower Threat Defense Software VPN Authentication DoS Vulnerability
https://notcve.org/view.php?id=CVE-2024-20331
A vulnerability in the session authentication functionality of the Remote Access SSL VPN feature of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to prevent users from authenticating. This vulnerability is due to insufficient entropy in the authentication process. An attacker could exploit this vulnerability by determining the handle of an authenticating user and using it to terminate their authentication session. A successful exploit could allow the attacker to force a user to restart the authentication process, preventing a legitimate user from establishing remote access VPN sessions. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asa-vpn-nyH3fhp https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-fmc-xss-M446vbEO https://sec.cloudapps.cisco.com/security/center/viewErp.x?alertId=ERP-75300 •
CVSS: 8.6EPSS: 0%CPEs: 37EXPL: 0CVE-2024-20330 – Cisco Firepower Threat Defense Software for Cisco Firepower 2100 Series TCP UDP Snort 2 and Snort 2 Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2024-20330
A vulnerability in the Snort 2 and Snort 3 TCP and UDP detection engine of Cisco Firepower Threat Defense (FTD) Software for Cisco Firepower 2100 Series Appliances could allow an unauthenticated, remote attacker to cause memory corruption, which could cause the Snort detection engine to restart unexpectedly. This vulnerability is due to improper memory management when the Snort detection engine processes specific TCP or UDP packets. An attacker could exploit this vulnerability by sending crafted TCP or UDP packets through a device that is inspecting traffic using the Snort detection engine. A successful exploit could allow the attacker to restart the Snort detection engine repeatedly, which could cause a denial of service (DoS) condition. The DoS condition impacts only the traffic through the device that is examined by the Snort detection engine. The device can still be managed over the network. Note: Once a memory block is corrupted, it cannot be cleared until the Cisco Firepower 2100 Series Appliance is manually reloaded. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd2100-snort-dos-M9HuMt75 https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-fmc-xss-M446vbEO https://sec.cloudapps.cisco.com/security/center/viewErp.x?alertId=ERP-75300 •
CVSS: 5.8EPSS: 0%CPEs: 225EXPL: 0CVE-2024-20299 – Cisco Adaptive Security Appliance and Firepower Threat Defense AnyConnect Access Control List Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2024-20299
A vulnerability in the AnyConnect firewall for Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to bypass a configured access control list (ACL) and allow traffic that should have been denied to flow through an affected device. This vulnerability is due to a logic error in populating group ACLs when an AnyConnect client establishes a new session toward an affected device. An attacker could exploit this vulnerability by establishing an AnyConnect connection to the affected device. A successful exploit could allow the attacker to bypass configured ACL rules. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asaftd-acl-bypass-VvnLNKqf https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-fmc-xss-M446vbEO https://sec.cloudapps.cisco.com/security/center/viewErp.x?alertId=ERP-75300 •
