Summaryinfo

A vulnerability marked as critical has been reported in Cisco NX-OS and FXOS. This impacts an unknown function of the component CLI. Performing a manipulation results in command injection. This vulnerability is identified as CVE-2019-1782. The attack is only possible with local access. There is not any exploit available.

Detailsinfo

A vulnerability, which was classified as critical, was found in Cisco NX-OS and FXOS (Router Operating System) (the affected version is unknown). This affects an unknown code of the component CLI. The manipulation with an unknown input leads to a command injection vulnerability. CWE is classifying the issue as CWE-77. The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

A vulnerability in the CLI of Cisco FXOS Software and Cisco NX-OS Software could allow an authenticated, local attacker to execute arbitrary commands on the underlying operating system of an affected device. This vulnerability is due to insufficient validation of arguments passed to certain CLI commands. An attacker could exploit this vulnerability by including malicious input as the argument of an affected command. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system with elevated privileges. An attacker would need administrator credentials to exploit this vulnerability.

The bug was discovered 05/15/2019. The weakness was released 05/15/2019 as cisco-sa-20190515-fxos-nxos-cm as confirmed advisory (Website). It is possible to read the advisory at tools.cisco.com. This vulnerability is uniquely identified as CVE-2019-1782 since 12/06/2018. Attacking locally is a requirement. A authentication is needed for exploitation.
