Moxa AWK-3131A Web Application onekey Information Disclosure Vulnerability(CVE-2016-0241)

### Summary An exploitable information disclosure vulnerability exists in the Web Application functionality of Moxa AWK-3131A Wireless Access Point. Retrieving a series of URLs without authentication can reveal sensitive configuration and system information to an attacker. ### Tested Versions Moxa AWK-3131A Series Industrial IEEE 802.11a/b/g/n wireless AP/bridge/client 1.1 ### Product URLs http://www.moxa.com/product/AWK-3131A.htm ### CVSSv3 Score 7.5 - CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N ### 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://<Device IP>/makeonekey.gz ``` Then ``` http://<Device IP>/getonekey.gz ``` ### Mitigation (optional) To significantly mitigate risk of exploitation, disable the web application before the device is deployed. ### Timeline * 2016-11-18 - Vendor Disclosure * 2017-04-10 - Public Release ### CREDIT * Discovered by Patrick DeSantis of Cisco Talos.
