CWE-78

A vulnerability in certain CLI commands of Cisco Identity Services Engine (ISE) could allow an authenticated, local attacker to execute arbitrary commands on the host operating system with the privileges of the local user, aka Command Injection. These commands should have been restricted from this user. The vulnerability is due to insufficient input validation of CLI command user input. An attacker could exploit this vulnerability by authenticating to the targeted device and issuing a CLI command with crafted user input. A successful exploit could allow the attacker to execute arbitrary commands on the affected system that should be restricted. The attacker would need to have valid user credentials for the device. Cisco Bug IDs: CSCvf49844.

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.

Multiple vulnerabilities in the CLI parser of Cisco IOS XE Software could allow an authenticated, local attacker to gain access to the underlying Linux shell of an affected device and execute arbitrary commands with root privileges on the device. The vulnerabilities are due to the affected software improperly sanitizing command arguments to prevent access to internal data structures on a device. An attacker who has user EXEC mode (privilege level 1) access to an affected device could exploit these vulnerabilities on the device by executing CLI commands that contain crafted arguments. A successful exploit could allow the attacker to gain access to the underlying Linux shell of the affected device and execute arbitrary commands with root privileges on the device.
