CVE-2019-1708: Cisco Adaptive Security Appliance Software and Cisco Firepower Threat Defense Software MOBIKE Denial of Service Vulnerability

A vulnerability in the Internet Key Exchange Version 2 Mobility and Multihoming Protocol (MOBIKE) feature for the Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a memory leak or a reload of an affected device that leads to a denial of service (DoS) condition. The vulnerability is due to the incorrect processing of certain MOBIKE packets. An attacker could exploit this vulnerability by sending crafted MOBIKE packets to an affected device to be processed. A successful exploit could cause an affected device to continuously consume memory and eventually reload, resulting in a DoS condition. The MOBIKE feature is supported only for IPv4 addresses.

Security readout for executives and security teams

CVE-2019-1708 can let an unauthenticated remote attacker disrupt Cisco ASA or FTD devices by abusing MOBIKE handling. Successful exploitation can drain memory or force reloads, causing denial of service for security gateway functions. Exposure is most likely on Cisco ASA or FTD deployments that process IKEv2 MOBIKE traffic over IPv4. The source bundle does not identify exact affected release ranges, so version applicability must be confirmed against Cisco guidance. Treat as high priority for internet-facing VPN or perimeter firewall infrastructure because the business impact is service outage, not data theft. Prioritize confirmation and vendor-directed remediation on exposed Cisco ASA and FTD devices. Mitigation focus: Check Cisco’s advisory for affected releases and fixed software guidance.; Upgrade or apply Cisco-recommended remediation where the advisory confirms applicability.; Limit exposed IKEv2/MOBIKE surfaces where operationally possible and vendor-supported..

Improper Resource Shutdown or Release

Improper Resource Shutdown or Release represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
