TITLE

Cisco Aironet Operates on the access point Cisco IOS of DHCP Service disruption in implementations (DoS) Vulnerabilities

Trust: 0.8

sources: JVNDB: JVNDB-2014-005463

DESCRIPTION

The DHCP implementation in Cisco IOS on Aironet access points does not properly handle error conditions with short leases and unsuccessful lease-renewal attempts, which allows remote attackers to cause a denial of service (device restart) by triggering a transition into a recovery state that was intended to involve a network-interface restart but actually involves a full device restart, aka Bug ID CSCtn16281. ( Reboot device ) There are vulnerabilities that are put into a state. Cisco Aironet Access Points are Cisco's wireless access point and bridge devices. A denial of service vulnerability exists in Cisco Aironet Access Points, which can exploit a vulnerability to initiate a denial of service attack. An attacker can exploit this issue to restart the affected device, which leads to a denial-of-service condition. This issue is being tracked by Cisco Bug ID CSCtn16281
