CVE-2020-9351Public exploitNetwork attack vector

Absolute-path disclosure via verbose XML error

Published Feb 23, 2020 · Updated Aug 4, 2024

Information disclosure in Isomorphic SmartClient 12.0 allows remote attackers to obtain the application's absolute path via malformed XML. The developer console endpoints accept malformed XML in the _transaction parameter and return a verbose server error containing the installation path. The disputed issue requires deployed developer tools without access controls; the disclosed value is a filesystem path, not file contents.
