Summaryinfo

A vulnerability was found in Cisco Identity Services Engine and classified as critical. This vulnerability affects unknown code of the component CLI. The manipulation results in os command injection. This vulnerability is identified as CVE-2018-0221. The attack is only possible with local access. There is not any exploit available.

Detailsinfo

A vulnerability was found in Cisco Identity Services Engine (Policy Management Software) (the affected version is unknown). It has been classified as problematic. Affected is an unknown code of the component CLI. The manipulation with an unknown input leads to a os command injection vulnerability. CWE is classifying the issue as CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

A vulnerability in specific CLI commands for the Cisco Identity Services Engine (ISE) could allow an authenticated, local attacker to perform command injection to the underlying operating system or cause a hang or disconnect of the user session. The attacker needs valid administrator credentials for the device. The vulnerability is due to incomplete input validation of user input for certain CLI ISE configuration commands. An attacker could exploit this vulnerability by authenticating as an administrative user, issuing a specific CLI command, and entering crafted, malicious user input for the command parameters. An exploit could allow the attacker to perform command injection to the lower-level Linux operating system. It is also possible the attacker could cause the ISE user interface for this management session to hang or disconnect. Cisco Bug IDs: CSCvg95479.
