Stored XSS via bypassable SVG script filtering

Published Mar 26, 2024 · Updated Aug 2, 2024

Stored XSS in Photo Gallery by 10Web 1.0.1 through 1.8.21 allows remote authenticated users to upload executable SVG content. UploadHandler.php rewrites SVG files with a regular expression that misses closing script tags containing whitespace, leaving embedded JavaScript intact. A user with image-upload permission must store the file, after which unauthenticated visitors can retrieve it and the script executes in their browsers.
