An attacker could exploit this vulnerability by injecting crafted command arguments into a vulnerable CLI command. An exploit could allow the attacker to execute arbitrary commands at the user\u0027s privilege level. On products that support multiple virtual device contexts (VDCs), this vulnerability could allow the attacker to execute commands at the user\u0027s privilege level outside the user\u0027s environment.\r\n\r\nThere are no workarounds that address this vulnerability.\r\n\r\n",
