PhreeBooks ERP 5.2.3 contains an arbitrary file upload vulnerability in the Image Manager component that allows authenticated attackers to upload malicious files by submitting requests to the image upload endpoint. Attackers can upload PHP files through the imgFile parameter to the bizuno/image/manager endpoint and execute them via the bizunoFS.php script for remote code execution.
An issue was discovered in PhreeBooksERP before 2017-02-13. The vulnerability exists due to insufficient filtration of user-supplied data in the "form" HTTP GET parameter passed to the "PhreeBooksERP-master/extensions/ShippingMethods/ups/label_mgr/js_include.php" and "PhreeBooksERP-master/extensions/ShippingMethods/yrc/label_mgr/js_include.php" URLs. An attacker could execute arbitrary HTML and script code in a browser in the context of the vulnerable website. NOTE: these js_include.php files do not exist in the SourceForge "stable release" (aka R37RC1).
