CVE-2024-12297

Frontend Authorization Logic Disclosure Vulnerability

Published Jan 15, 2025 CVSS 4.0 · 9.2 Critical EPSS < 1% KEV · Not listed
Description
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.
