CVE-2017-3863
HighSummary
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.
Risk Assessment
An attacker could exploit these vulnerabilities by sending crafted EnergyWise packets to be processed by an affected device, potentially leading to device failure and service interruption. This poses a significant risk to the continuity of organizational operations.
Recommendation
It is recommended to update Cisco IOS and Cisco IOS XE software to the latest versions that address these vulnerabilities. Additionally, monitoring network traffic for suspicious EnergyWise packets is advisable.
Other vulnerabilities in Cisco IOS, Cisco IOS XE
See all- CVE-2016-6414High
In Cisco IOS, possibly version 15.6 and earlier, and IOS XE, possibly version 3.18 and earlier, local users can execute arbitrary IOx Linux commands on the guest OS via crafted iox command-line options.
- CVE-2014-3360High
Cisco IOS versions 12.4 and 15.0 through 15.4 and IOS XE 3.1.xS to 3.11.xS before 3.12S are vulnerable to an attack that can lead to denial of service via a crafted SIP message.
- CVE-2014-3357High
Cisco IOS versions 15.0, 15.1, 15.2, and 15.4, as well as IOS XE versions 3.3.xSE before 3.3.2SE, 3.3.xXO before 3.3.1XO, 3.5.xE before 3.5.2E, and 3.11.xS before 3.11.1S are vulnerable to an attack that can cause a denial of service via malformed mDNS packets.
Original NVD description (English source)
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 CSCut50727.
