Multiple vulnerabilities in the EnergyWise module of Cisco IOS and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a buffer overflow condition or a reload of an affected device, leading to a denial of service (DoS) condition.

These vulnerabilities are due to improper parsing of crafted EnergyWise packets destined to an affected device. An attacker could exploit these vulnerabilities by sending crafted EnergyWise packets to be processed by an affected device. An exploit could allow the attacker to cause a buffer overflow condition or a reload of the affected device, leading to a DoS condition.

Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities.
