Vulnerability from variot

A vulnerability in the NX-API feature of Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause an NX-API system process to unexpectedly restart. The vulnerability is due to incorrect validation of the HTTP header of a request that is sent to the NX-API. An attacker could exploit this vulnerability by sending a crafted HTTP request to the NX-API on an affected device. A successful exploit could allow the attacker to cause a denial of service (DoS) condition in the NX-API service; however, the NX-OS device itself would still be available and passing network traffic. Note: The NX-API feature is disabled by default. Cisco NX-OS The software contains an input validation vulnerability.Service operation interruption (DoS) There is a possibility of being put into a state. Cisco NX-OS Software is a data center-level operating system software used by a set of switches of Cisco. The following products and versions are affected: Cisco MDS 9000 Series Multilayer Switches; Nexus 3000 Series Switches; Nexus 3500 Platform Switches; Nexus 3600 Platform Switches; Nexus 5500 Platform Switches; Nexus 5600 Platform Switches; 7700 Series Switches; Nexus 9000 Series Switches (standalone NX-OS mode); Nexus 9500 R-Series Switching Platform
