Description

SNMP agents in 3Com AirConnect and Symbol Access Point may allow a remote attacker to obtain the WEP encryption key. The issue is triggered when the SNMP agents reveals the WEP encryption key in response to SNMP queries for the dot11WEPDefaultKeysTable in the IEEE 802.11 MIB or the the ap128bWEPKeyTable in the 3ComAP MIB. It is possible that the flaw may allow a remote attacker to undermine authentication and privacy protection mechanisms for wireless clients, resulting in further access to the wireless network.
