Last Revised
Cisco has observed increasingly complex attacks that could allow an attacker to gain administrative access to a Cisco IOS device by installing a malicious ROMMON image. Successful exploitation using this image could allow an attacker to manipulate device behavior after the device is rebooted.
US-CERT encourages users and administrators to review the Cisco Security Activity Bulletin and apply recommendations to protect Cisco IOS devices.
