CVE-2020-7001Network attack vector

Confidential-information disclosure via weak configuration encryption

Published Mar 24, 2020 · Updated Aug 4, 2024

Weak cryptography in Moxa EDS-G516E Series firmware 5.2 and earlier allows remote attackers to disclose confidential information. The configuration-file encryption function applies a broken or risky algorithm to backed-up configuration data; Moxa does not disclose the algorithm or implementation defect. Exploitation requires network reachability, and published material does not identify the exposed data or request path.
