CVE-2020-15015Public exploitNetwork attack vector

Cross-site scripting via executable SVG uploads

Published Jun 24, 2020 · Updated Aug 4, 2024

Cross-site scripting in FileExplorer in GleamTech FileUltimate 6.1.5.0 allows remote attackers to run script via an uploaded SVG document. FileExplorer opens the uploaded SVG without neutralizing its embedded script element, causing the browser to execute the payload in the application origin. Exploitation requires a user to open the crafted SVG; the script can read or modify data available to that browser session, while no service interruption is reported.
