CVE-2018-0193

CVE-2018-0193 describes multiple command injection vulnerabilities in the CLI parser of Cisco IOS XE Software. An authenticated, local attacker can exploit insufficient sanitization of command arguments to inject arbitrary commands, gaining root-level access to the underlying Linux shell. With a CVSS score of 7.8 (HIGH), this vulnerability allows for complete compromise of confidentiality, integrity, and availability. While no public exploit code or active exploitation has been observed, and community discussion is minimal, the potential for a local attacker to achieve root privileges makes it a significant concern for affected Cisco IOS XE devices.
