Piwigo is a full featured open source photo gallery application for the web. Prior to 16.4.0, admin/themes_standard_pages.php validates uploaded logo content by MIME type but reuses the attacker-controlled extension from std_pgs_logo when constructing the stored filename. An authenticated administrator can upload image content with a server-executable final extension, causing the file to be placed in the web-accessible logo directory and executed when requested if the web server handles that extension. This can permit arbitrary command execution, data disclosure, modification, persistence, and service disruption. This vulnerability is fixed in 16.4.0.
