Details

An exploitable information disclosure vulnerability exists in the Web Application functionality of Moxa AWK-3131A Series Industrial IEEE 802.11a/b/g/n wireless AP/bridge/client. Retrieving a series of URLs without authentication can reveal sensitive configuration and system information to an attacker.

Specifically, an unauthenticated attacker can visit http:///makeonekey.gz and then http:///getonekey.gz to obtain compressed file which contains systemlog.log, config.ini, and the system_status folder. These files contain sensitive information, including encoded credentials for system services and wireless interfaces.

Exploit Proof-of-Concept (optional)

First http:///makeonekey.gz Then http:///getonekey.gz

Mitigation (optional)

To significantly mitigate risk of exploitation, disable the web application before the device is deployed.
