To determine whether the Clientless or An圜onnect SSL VPN is configured to use digital certificate authentication, use the show runing-config webvpn command. Cisco ASDM is configured to use digital certificate authentication.Clientless or An圜onnect SSL VPN is configured to use digital certificate authentication.

Inspect: sqlnet, packet 0, drop 0, reset-drop 0 Note: SQL*Net inspection is enabled by default.ĭigital Certificate Authentication Bypass VulnerabilityĬisco ASA Software is affected by this vulnerability in either of the following cases: The following example shows the Cisco ASA Software with SQL*Net inspection enabled:Ĭiscoasa# show service-policy | include sqlnet To determine whether the SQL*Net inspection is enabled, use the show service-policy | include sqlnet command and verify that an output is returned. SQL*Net Inspection Engine Denial of Service VulnerabilityĬisco ASA Software is affected by this vulnerability if SQL*Net inspection is enabled. The following example shows a Cisco ASA with a crypto map called outside_map that is applied to the outside interface:Ĭrypto map outside_map interface outside Note: Cisco ASA Software does not have a crypto map applied by default to any interface. To determine whether the Cisco ASA Software is configured for IPsec VPN use, the command show running-config crypto map and verify that a crypto map is applied to at least one interface of the Cisco ASA. This vulnerability cannot be exploited if offending packets are flowing through an SSL/TLS based VPN tunnel. To be vulnerable, Cisco ASA Software must have at least one IPsec VPN tunnel with active traffic passing through the tunnel. IPsec VPN Crafted ICMP Packet Denial of Service Vulnerability A separate Cisco Security Advisory has been published to disclose the vulnerabilities that affect the Cisco FWSM.

Note: The Cisco Firewall Services Module (FWSM) for Cisco Catalyst 6500 Series Switches and Cisco 7600 Series Routers may be affected by the SQL*Net Inspection Engine Denial of Service Vulnerability. This advisory is available at the following link: Workarounds are available for some of the vulnerabilities. Successful exploitation of the Crafted ICMP Packet Denial of Service Vulnerability may cause valid connections that are passing through the affected system to be dropped, or cause a reload of the system, leading to a denial of service (DoS) condition.Ĭisco has released software updates that address these vulnerabilities. Successful exploitation of the An圜onnect SSL VPN Memory Exhaustion Denial of Service Vulnerability may exhaust available memory, which could result in general system instability and cause the affected system to become unresponsive and stop forwarding traffic. Successful exploitation of the Digital Certificate Authentication Bypass Vulnerability, Remote Access VPN Authentication Bypass Vulnerability, and Digital Certificate HTTP Authentication Bypass Vulnerability may result in an authentication bypass, which could allow the attacker access to the inside network via remote access VPN or management access to the affected system via the Cisco Adaptive Security Device Management (ASDM). Successful exploitation of the IPsec VPN Crafted ICMP Packet Denial of Service Vulnerability, SQL*Net Inspection Engine Denial of Service Vulnerability, HTTP Deep Packet Inspection Denial of Service Vulnerability, DNS Inspection Denial of Service Vulnerability, and SSL VPN Web Portal Denial of Service Vulnerability may result in a reload of an affected device, leading to a denial of service (DoS) condition. These vulnerabilities are independent of one another a release that is affected by one of the vulnerabilities may not be affected by the others.
