Cisco warns of wireless security hole
Customers using Aironet wireless access points are vulnerable
By Paul Roberts, IDG News Service December 03, 2003
Cisco Systems Inc. is warning customers using its Aironet wireless
access points (APs) about a security vulnerability that could allow
attackers to obtain keys used to secure communications on wireless networks.
The vulnerability affects Aironet 1100, 1200 and 1400 series access
points and could allow WEP (Wired Equivalent Privacy) keys to be sent as
plain text over corporate networks that use an SNMP (Simple Network
Management Protocol) server and have a specific option enabled on the
access point, Cisco said.
SNMP is a network management protocol that allows companies to monitor
the operation of network devices using a central server and software
agents that track and report on the functioning of SNMP-compliant devices.
To be vulnerable, organizations have to be using an affected Aironet
model with the IOS software, have an SNMP server deployed, be using
static WEP keys for encryption and have enabled an option on the AP
called "snmp-server enable traps wlan-wep." That option is disabled by
default on Aironet access points, Cisco said.
