A vulnerability in ICMPv6 inspection when configured with the Snort 2 detection engine for Cisco Firepower Threat Defense (FTD) Software or Cisco FirePOWER Services could allow an unauthenticated, remote attacker to cause the CPU of an affected device to spike to 100 percent, which could stop

A vulnerability in the CLI parser of Cisco FirePOWER Software for Adaptive Security Appliance (ASA) FirePOWER module could allow an authenticated, remote attacker to execute arbitrary commands on the underlying operating system of an affected ASA FirePOWER module as the root user. This vulnerability is due to improper handling of undefined command parameters. An attacker could exploit this vulnerability by using a crafted command on the CLI or by submitting a crafted HTTPS request to the web-based management interface of the Cisco ASA that is hosting the ASA FirePOWER module. Note: To exploit this vulnerability, the attacker must have administrative access to the Cisco ASA. A user who has administrative access to a particular Cisco ASA is also expected to have administrative access to the ASA FirePOWER module that is hosted by that Cisco ASA.

A vulnerability in the CLI of Cisco FXOS Software and Cisco NX-OS Software could allow an authenticated, local attacker to execute arbitrary commands on the underlying Linux operating system with the privilege level of root. The vulnerability is due to insufficient validation of arguments passed to a specific CLI command on the affected device. An attacker could exploit this vulnerability by including malicious input as the argument of an affected command. A successful exploit could allow the attacker to execute arbitrary commands on the underlying Linux operating system with elevated privileges. An attacker would need valid administrator credentials to exploit this vulnerability.

The Adaptive Security Appliance (ASA) 5585-X FirePOWER Security Services Processor (SSP) module for Cisco ASA with FirePOWER Services 5.3.1 through 6.0.0 misconfigures kernel logging, which allows remote attackers to cause a denial of service (resource consumption, and inspection outage or module outage) via a flood of crafted IP traffic, aka Bug ID CSCux19922.

Cisco FireSIGHT System Software 5.4.0 through 6.0.1 and ASA with FirePOWER Services 5.4.0 through 6.0.0.1 allow remote attackers to bypass malware protection via crafted fields in HTTP headers, aka Bug ID CSCux22726.
