Moxa MGate MB3180 before 1.8, MGate MB3280 before 2.7, MGate MB3480 before 2.6, MGate MB3170 before 2.5, and MGate MB3270 before 2.7 use weak encryption, which allows remote attackers to bypass authentication via a brute-force series of guesses for a parameter value.
Moxa Device Server Web Console 5232-N allows remote attackers to bypass authentication, and consequently modify settings and data, via vectors related to reading a cookie parameter containing a UserId value.
Moxa PT-7728 devices with software 3.4 build 15081113 allow remote authenticated users to change the configuration via vectors involving a local proxy.
Moxa UC-7408 LX-Plus devices allow remote authenticated users to write to the firmware, and consequently render a device unusable, by leveraging root access.
Moxa MiiNePort_E1_4641 devices with firmware 1.1.10 Build 09120714, MiiNePort_E1_7080 devices with firmware 1.1.10 Build 09120714, MiiNePort_E2_1242 devices with firmware 1.1 Build 10080614, MiiNePort_E2_4561 devices with firmware 1.1 Build 10080614, and MiiNePort E3 devices with firmware 1.0 Build 11071409 have a blank default password, which allows remote attackers to obtain access via unspecified vectors.
Moxa Secure Router EDR-G903 devices before 3.4.12 do not delete copies of configuration and log files after completing the import function, which allows remote attackers to obtain sensitive information by requesting these files at an unspecified URL.
Moxa Secure Router EDR-G903 devices before 3.4.12 allow remote attackers to cause a denial of service (cold start) by sending two crafted ping requests.
