A weak Cookie parameter is used in the web application of Moxa OnCell G3100-HSPA Series version 1.4 Build 16062919 and prior. An attacker can brute force parameters required to bypass authentication and access the web interface to use all its functions except for password change.

CSRF tokens are not used in the web application of Moxa OnCell G3100-HSPA Series version 1.4 Build 16062919 and prior, which makes it possible to perform CSRF attacks on the device administrator.

An issue was discovered on Moxa AWK-3121 1.19 devices. It provides functionality so that an administrator can change the name of the device. However, the same functionality allows an attacker to execute XSS by injecting an XSS payload. The POST parameter "iw_board_deviceName" is susceptible to this injection.

An issue was discovered on Moxa AWK-3121 1.14 devices. It provides functionality so that an administrator can run scripts on the device to troubleshoot any issues. However, the same functionality allows an attacker to execute commands on the device. The POST parameter "iw_filename" is susceptible to command injection via shell metacharacters.

An issue was discovered on Moxa AWK-3121 1.14 devices. The session cookie "Password508" does not have an HttpOnly flag. This allows an attacker who is able to execute a cross-site scripting attack to steal the cookie very easily.

An issue was discovered on Moxa AWK-3121 1.14 devices. 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.

An issue was discovered on Moxa AWK-3121 1.14 devices. It provides functionality so that an administrator can run scripts on the device to troubleshoot any issues. However, the same functionality allows an attacker to execute commands on the device. The POST parameter "iw_filename" is susceptible to buffer overflow. By crafting a packet that contains a string of 162 characters, it is possible for an attacker to execute the attack.

An issue was discovered on Moxa AWK-3121 1.14 devices. The device enables an unencrypted TELNET service by default. This allows an attacker who has been able to gain an MITM position to easily sniff the traffic between the device and the user. Also an attacker can easily connect to the TELNET daemon using the default credentials if they have not been changed by the user.

An issue was discovered on Moxa AWK-3121 1.14 devices. It provides alert functionality so that an administrator can send emails to his/her account when there are changes to the device's network. However, the same functionality allows an attacker to execute commands on the device. The POST parameters "to1,to2,to3,to4" are all susceptible to buffer overflow. By crafting a packet that contains a string of 678 characters, it is possible for an attacker to execute the attack.

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.
