A vulnerability in the Remote Access VPN (RAVPN) service 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) of the RAVPN service. This vulnerability is due to resource exhaustion. An attacker could exploit this vulnerability by sending a large number of VPN authentication requests to an affected device. A successful exploit could allow the attacker to exhaust resources, resulting in a DoS of the RAVPN service on the affected device. Depending on the impact of the attack, a reload of the device may be required to restore the RAVPN service. Services that are not related to VPN are not affected. Cisco Talos discussed these attacks in the blog post Large-scale brute-force activity targeting VPNs, SSH services with commonly used login credentials. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asaftd-bf-dos-vDZhLqrW • CWE-772: Missing Release of Resource after Effective Lifetime •

A vulnerability in the web-based management interface of Cisco Secure Firewall Management Center (FMC) Software could allow an authenticated, remote attacker to conduct SQL injection attacks on an affected system. This vulnerability exists because the web-based management interface does not validate user input adequately. An attacker could exploit this vulnerability by authenticating to the application as an Administrator and sending crafted SQL queries to an affected system. A successful exploit could allow the attacker to obtain unauthorized data from the database and make changes to the system. To exploit this vulnerability, an attacker would need Administrator-level privileges. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-fmc-sql-inj-LOYAFcfq • CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') •

A vulnerability in the geolocation access control feature of Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to bypass an access control policy. This vulnerability is due to improper assignment of geolocation data. An attacker could exploit this vulnerability by sending traffic through an affected device. A successful exploit could allow the attacker to bypass a geolocation-based access control policy and successfully send traffic to a protected device. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-geoip-bypass-MB4zRDu • CWE-229: Improper Handling of Values •
