Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. A vulnerability in the CLI implementation of a specific command for the Cisco UCS Fabric Interconnect could have allowed an authenticated, local attacker to escape the CLI and gain unauthorized access to the underlying operating system of the device.
An attacker could have exploited this vulnerability to escape the CLI and execute arbitrary commands on the underlying operating system with the privileges of the root user. The attacker would need valid device credentials.
Additional information on Cisco's security vulnerability policy can be found at the following URL:. Security Vulnerability Policy. A successful exploit could allow the attacker to cause the SNMP application to restart multiple times, leading to a system-level restart and a denial of service DoS condition.
These BIOS revisions include the updated microcode that is a required part of the mitigation for these vulnerabilities. This release includes the BIOS revision to mitigate this risk. This issue is resolved through the OpenSSL software updates. Operating System and Hypervisor patches from the appropriate vendors may also be required to mitigate these vulnerabilities.
CVE is addressed by applying the updated processor microcode from Intel included in the server firmware bundle, and the relevant Operating System and Hypervisor patches from the appropriate vendors. The vulnerability occurs because AAA processes prevent the NX-OS System Manager from receiving keepalive messages when an affected device receives a high rate of login attempts, such as in a brute-force login attack.
System memory can run low on the FXOS devices under the same conditions, which could cause the AAA process to unexpectedly restart or cause the device to reload. An attacker could exploit this vulnerability by performing a brute-force login attack against a device that is configured with AAA security services.
A successful exploit could allow the attacker to cause the affected device to reload. There are workarounds that address this vulnerability. The Incomplete or no cache-control and Pragma HTTP header set vulnerability vulnerability will not be fixed because of the following:. Future UCS software driver bundles distributed through the usual Cisco software channels may not include binaries for the libfabric packages.
Cisco engineers continue to be active, core contributors in both the Libfabric and Open MPI communities, and will actively develop and support users through the usual community or commercial ISV support mechanisms e.
