Horizon Alert
Summary of the vulnerability and why it matters
This vulnerability affects Cisco IOS Software and Cisco IOS XE Software, specifically within the Autonomic Networking feature. The flaw could enable an attacker in close proximity to cause affected devices to restart, leading to service disruptions. This impacts the availability of network services managed by the affected systems.
- Autonomic Networking feature in Cisco software
- Allows attacker-initiated device reloads
- Network service disruption
Attack Path
How an attacker could exploit the issue
An unauthenticated attacker on an adjacent network can exploit a vulnerability in the Autonomic Networking feature. This allows the attacker to send a crafted request that causes affected Cisco devices to reload. This action can disrupt network services by causing a denial-of-service condition for autonomic nodes.
- Adjacent network access required.
- Attacker sends a crafted request.
- Autonomic nodes reload, causing DoS.
Live Threat
