CISCO ASAV FIPS ERROR WINDOWS

Note: This vulnerability affects only Cisco ASA Software Release 9.16.1 and Cisco FTD Software Release 7.0.0. This vulnerability is fixed for Cisco Firepower NGFW Virtual by Cisco_FTD_Patch-7.0.0.1-15.sh.REL.tar.

CISCO ASAV FIPS ERROR SERIES

This vulnerability is fixed for Cisco Firepower 2100 Series by Cisco_FTD_SSP_FP2K_Patch-7.0.0.1-15.sh.REL.tar. This vulnerability is fixed in Cisco ASA Software releases 9.16.1.28 and later. For further information on determining if FIPS is configured for Cisco FTD Software, see the Security Certifications Compliance chapter of the Firepower Management Center Configuration Guide.

In Cisco FTD Software, FIPS mode is enabled indirectly by configuring either Common Criteria (CC) mode or Unified Capabilities Approved Products List (UCAPL) mode.

For ASA Software, the administrator can issue the show running-config | include fips-enable command and if the output contains the fips-enable keyword the device is considered not vulnerable.

The device is considered not vulnerable if FIPS mode is enabled: The administrator can issue the show running-config command and check for the tunnel protection ipsec command.

If there is a crypto IPsec profile bound to a tunnel interface in the configuration.

The administrator can issue the show running-config command and check for the crypto map interface command.

If there is a crypto map bound to an interface in the configuration.

The device should be considered vulnerable if either of these configuration parameters exists on the device: Note: These devices are not vulnerable if Federal Information Processing Standards Publication (FIPS) mode is enabled.

This vulnerability affects the following Cisco products if they are running Cisco ASA Software Release 9.16.1 or Cisco FTD Software Release 7.0.0 and are configured to support IPsec connections to the device.Īdaptive Security Virtual Appliance (ASAv) Important: Successful exploitation of this vulnerability would not cause a compromise of any encrypted data, Cisco stated in its advisory. A successful exploit could cause the device to crash, forcing it to reload. An attacker could exploit this vulnerability by sending malicious packets over an established IPsec connection. The vulnerability CVE-2021-1422 is rated as 7.7 out of 10 occurred due to a logic error in how the software cryptography module handles specific types of decryption errors. The flaw resides in the software cryptography module of both ASA and FTD software, an attacker in a man-in-the-middle position could exploit the issue to trigger a DoS condition and cause an unexpected reload of a vulnerable device. Running the tool NMAP against the outside interface IP address we can confirm the TLS protocols and ciphers enabled as default.Cisco released security updates for a high severity vulnerability in the Adaptive Security Appliance (ASA) and Firepower Threat Defense (FTD) products. IP addresses, basic routing and SSL Remote Access VPN is configured, the SSL configuration is using default settings. In our scenario we have a Cisco ASAv appliance running version 9.14(1).

This post describes the steps to disable the older TLS protocols and ensure the strongest ciphers are enabled.

Be careful with older version of windows such as unpatched Windows 7, TLSv1.0 is enabled as default and TLSv1.1 and TLSv1.2 have to be manually enabled.

CISCO ASAV FIPS ERROR WINDOWS 10

Most modern operating systems such as Windows 10 come with TLS version 1.2 support as default, so versions 1.0 and 1.1 can safely be disabled. TLS versions 1.0 and 1.1 are considered insecure and depreciated in most browsers/operating systems. When using a Cisco ASA firewall for SSL/TLS Remote Access VPN or managing the device using ASDM, the appliance is enabled by default with TLS versions 1.0, 1.1 and 1.2.
