CVE-2018-0283
https://notcve.org/view.php?id=CVE-2018-0283
A vulnerability in the detection engine of Cisco Firepower System Software could allow an unauthenticated, remote attacker to restart an instance of the Snort detection engine on an affected device, resulting in a brief denial of service (DoS) condition. The vulnerability is due to the incorrect handling of Transport Layer Security (TLS) TCP connection setup for the affected software. An attacker could exploit this vulnerability by sending crafted TLS traffic to an affected device. A successful exploit could allow the attacker to cause the Snort detection engine on the affected device to restart, resulting in a DoS condition.

CVE-2018-0281
https://notcve.org/view.php?id=CVE-2018-0281
A vulnerability in the detection engine of Cisco Firepower System Software could allow an unauthenticated, remote attacker to restart an instance of the Snort detection engine on an affected device, resulting in a brief denial of service (DoS) condition. The vulnerability is due to the incorrect handling of a Transport Layer Security (TLS) extension during TLS connection setup for the affected software. An attacker could exploit this vulnerability by sending a crafted TLS connection setup request to an affected device. A successful exploit could allow the attacker to cause the Snort detection engine on the affected device to restart, resulting in a DoS condition.

CVE-2018-0278
https://notcve.org/view.php?id=CVE-2018-0278
A vulnerability in the management console of Cisco Firepower System Software could allow an unauthenticated, remote attacker to access sensitive data about the system. The vulnerability is due to improper cross-origin domain protections for the WebSocket protocol. An attacker could exploit this vulnerability by convincing a user to visit a malicious website designed to send requests to the affected application while the user is logged into the application with an active session cookie. A successful exploit could allow the attacker to retrieve policy or configuration information from the affected software and to perform another attack against the management console.

CVE-2018-0233
https://notcve.org/view.php?id=CVE-2018-0233
A vulnerability in the Secure Sockets Layer (SSL) packet reassembly functionality of the detection engine in Cisco Firepower System Software could allow an unauthenticated, remote attacker to cause the detection engine to consume excessive system memory on an affected device, which could cause a denial of service (DoS) condition. The vulnerability is due to the affected software improperly handling changes to SSL connection states. An attacker could exploit this vulnerability by sending crafted SSL connections through an affected device. A successful exploit could allow the attacker to cause the detection engine to consume excessive system memory on the affected device, which could cause a DoS condition. The device may need to be reloaded manually to recover from this condition. • http://www.securityfocus.com/bid/103930 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180418-fpsnort • CWE-400: Uncontrolled Resource Consumption •
CVE-2017-12245
https://notcve.org/view.php?id=CVE-2017-12245
A vulnerability in SSL traffic decryption for Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause depletion of system memory, aka a Firepower Detection Engine SSL Decryption Memory Consumption Denial of Service vulnerability. If this memory leak persists over time, a denial of service (DoS) condition could develop because traffic can cease to be forwarded through the device. The vulnerability is due to an error in how the Firepower Detection Snort Engine handles SSL traffic decryption and notifications to and from the Adaptive Security Appliance (ASA) handler. An attacker could exploit this vulnerability by sending a steady stream of malicious Secure Sockets Layer (SSL) traffic through the device. An exploit could allow the attacker to cause a DoS condition when the device runs low on system memory. • http://www.securityfocus.com/bid/101118 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20171004-ftd • CWE-399: Resource Management Errors CWE-772: Missing Release of Resource after Effective Lifetime •
