An attacker could exploit this vulnerability by placing a crafted file into a specific location on an affected device. A successful exploit could allow the attacker to execute arbitrary code at boot time.\r\n\r Because this allows the attacker to bypass a major security feature of the device, Cisco has raised the Security Impact Rating (SIR) of this advisory from Medium to High.", "affected": [ { "vendor": "Cisco", "product": "IOS", "versions": [ { "version": "15.0(1)XO1", "status": "affected" }, { "version":
