Symbol Access Portable Data Terminal (PDT) 8100 does not hide the default WEP keys if they are not changed, which could allow attackers to retrieve the keys and gain access to the wireless network.

SNMP agents in 3Com AirConnect AP-4111 and Symbol 41X1 Access Point allow remote attackers to obtain the WEP encryption key by reading it from a MIB when the value should be write-only, via (1) dot11WEPDefaultKeyValue in the dot11WEPDefaultKeysTable of the IEEE 802.11b MIB, or (2) ap128bWepKeyValue in the ap128bWEPKeyTable in the Symbol MIB.
