Moxa’s Ethernet switch is vulnerable to an authentication bypass because of flaws in its authorization mechanism. Although both client-side and back-end server verification are involved in the process, attackers can exploit weaknesses in its implementation. These vulnerabilities may enable brute-force attacks to guess valid credentials or MD5 collision attacks to forge authentication hashes, potentially compromising the security of the device.
Solution:
Workaround:
The product uses a protection mechanism whose strength depends heavily on its obscurity, such that knowledge of its algorithms or key data is sufficient to defeat the mechanism.
