Name of the Vulnerable Software and Affected Versions Moxa MXView versions 3.x through 3.2.2

Description The issue is related to the use of hard-coded passwords in the Moxa MXView Network Management software. This could allow a remote attacker to gain unauthorized access to protected information using default passwords.

Recommendations For versions 3.x through 3.2.2, update the software to a version that does not use hard-coded passwords, or change the default passwords to custom ones to prevent exploitation. As a temporary workaround, consider disabling the use of default passwords until a patch is available. Restrict access to the software to minimize the risk of exploitation.
