An attacker could exploit this vulnerability by injecting crafted command arguments into a vulnerable CLI command for the affected operating system. A successful exploit could allow the attacker to overwrite or modify arbitrary files that are stored in the flash memory of an affected system. To exploit this vulnerability, the attacker would need to authenticate to an affected system by using valid administrator credentials. Cisco Bug IDs: CSCvf93335.
