Detailsinfo

A vulnerability was found in Cicoandcico ASA and Firepower Threat Defense (unknown version). It has been rated as problematic. Affected by this issue is an unknown code block of the component Cryptographic Hardware Accelerator Driver. The manipulation with an unknown input leads to a resource consumption vulnerability. Using CWE to declare the problem leads to CWE-400. The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources. Impacted is availability. CVE summarizes:

A vulnerability in the cryptographic hardware accelerator driver of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a temporary denial of service (DoS) condition. The vulnerability exists because the affected devices have a limited amount of Direct Memory Access (DMA) memory and the affected software improperly handles resources in low-memory conditions. An attacker could exploit this vulnerability by sending a sustained, high rate of malicious traffic to an affected device to exhaust memory on the device. A successful exploit could allow the attacker to exhaust DMA memory on the affected device, which could cause the device to reload and result in a temporary DoS condition.

The bug was discovered 10/03/2018. The weakness was disclosed 10/05/2018 as cisco-sa-20181003-asa-dma-dos as confirmed advisory (Website). The advisory is shared for download at tools.cisco.com. This vulnerability is handled as CVE-2018-15383 since 08/17/2018. The attack may be launched remotely. No form of authentication is required for exploitation. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1499.

The vulnerability scanner Nessus provides a plugin with the ID 117917 (Cisco Firepower Threat Defense Software Multiple DoS Vulnerabilities (cisco-sa-20181003-ftd-inspect-dos, cisco-sa-20181003-asa-dma-dos)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family CISCO and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 316337 (Cisco Adaptive Security Appliance Direct Memory Access Denial of Service Vulnerability(cisco-sa-20181003-webex-rce)).

Upgrading eliminates this vulnerability. A possible mitigation has been published even before and not after the disclosure of the vulnerability.

The vulnerability is also documented in the vulnerability database at Tenable (117917). The entry VDB-124896 is pretty similar. Once again VulDB remains the best source for vulnerability data.
