Multiple directory traversal vulnerabilities in the iBrowser plugin library, as used in Open Journal Systems before 2.3.7, allow remote authenticated users to (1) delete or (2) rename arbitrary files via a .. (dot dot) in the param parameter to lib/pkp/lib/tinymce/jscripts/tiny_mce/plugins/ibrowser/scripts/rfiles.php.

Incomplete blacklist vulnerability in Open Journal Systems before 2.3.7 allows remote authenticated users with the Author Role permission to execute arbitrary code by uploading a file with an executable extension that is not ".php", then accessing it via a direct request to the file in submission/original/ in the associated article directory, as demonstrated using .pHp, .asp, and other extensions.

Multiple cross-site scripting (XSS) vulnerabilities in Open Journal Systems before 2.3.7 allow remote attackers and remote authenticated users to inject arbitrary web script or HTML via the (1) editor or (2) callback parameters to lib/pkp/lib/tinymce/jscripts/tiny_mce/plugins/ibrowser/ibrowser.php in the iBrowser plugin, (3) authors[][url] parameter to index.php, or (4) Bio Statement or (5) Abstract of Submission fields to the stripUnsafeHtml function in lib/pkp/classes/core/String.inc.php.
