CVE-2024-12297: Moxa Eds-508a Series

Critical severity, CVSS 9.2. EPSS: 0.8% chance of exploitation in the next 30 days.

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.
