CVE-2018-15819Public exploitNetwork attack vector

Unauthenticated credential disclosure via session-token acceptance

Published Mar 2, 2020 · Updated Aug 5, 2024

Authentication bypass in EasyIO EasyIO-30P before 2.0.5.27 allows remote attackers to read stored user credentials via webuser.js. The web interface accepts an attacker-supplied session token for webuser.js and returns credential data without validating an authenticated session. No account or user interaction is required, and the documented consequence is credential disclosure rather than configuration changes or service interruption.
