Name of the Vulnerable Software and Affected Versions Dotclear versions prior to 2.10.3

Description The issue allows remote authenticated users with permissions to manage media items to execute arbitrary code by uploading a ZIP file containing a file with a crafted extension. This can be achieved by uploading a ZIP file with a file that has an extension such as .php.txt or .php%20.

Recommendations For versions prior to 2.10.3, update to version 2.10.3 or later to resolve the issue. As a temporary workaround, consider restricting access to the fileUnzip->unzip method or limiting the types of files that can be uploaded to prevent exploitation.
