CVE-2017-3860: Buffer Overflow
Published Apr 20, 2017
·Updated
Multiple vulnerabilities in the EnergyWise module of Cisco IOS (12.2 and 15.0 through 15.6) and Cisco IOS XE (3.2 through 3.18) 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 IOS Software and Cisco IOS XE Software support EnergyWise for IPv4 communication. Only IPv4 packets destined to a device configured as an EnergyWise domain member can trigger these vulnerabilities. IPv6 packets cannot be used to trigger these vulnerabilities. Cisco Bug ID CSCur29331.

Remediation
Recommended actions to resolve this vulnerability, in priority order.
- Compensating control
Limit/permit EnergyWise (IPv4) traffic only from required sources, because only IPv4 packets destined to a device configured as an EnergyWise domain member can trigger the EnergyWise vulnerabilities.
- Compensating control
Do not use or permit EnergyWise over IPv6 for exposure, since IPv6 packets cannot be used to trigger these vulnerabilities.
