A vulnerability in the dragonite debugger of Cisco IOS XE Software could allow an authenticated, local attacker to escalate from privilege level 15 to root privilege. The vulnerability is due to the presence of development testing and verification scripts that remained on the device. An attacker could exploit this vulnerability by bypassing the consent token mechanism with the residual scripts on the affected device. A successful exploit could allow the attacker to escalate from privilege level 15 to root privilege.
