Name of the Vulnerable Software and Affected Versions: Cisco IOS XE Software (affected versions not specified)

Description: The issue is related to multiple vulnerabilities in the CLI parser of Cisco IOS XE Software. These vulnerabilities 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 by executing CLI commands that contain crafted arguments.

Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
