ClipBucket V5 provides open source video hosting with PHP. Prior to 5.5.1 - 239, a file upload vulnerability exists in the Manage Playlist functionality of the application, specifically surrounding the uploading of playlist cover images. Without proper checks, an attacker can upload a PHP script file instead of an image file, thus allowing a webshell or other malicious files to be stored and executed on the server. This attack vector exists in both the admin area and low-level user area. This vulnerability is fixed in 5.5.1 - 239.

ClipBucket V5 provides open source video hosting with PHP. Prior to 5.5.1 - 238, ClipBucket V5 allows unauthenticated attackers to change the template directory via a directory traversal, which results in a denial of service.

ClipBucket V5 provides open source video hosting with PHP. During the user avatar upload workflow, a user can choose to upload and change their avatar at any time. During deletion, ClipBucket checks for the avatar_url as a filepath within the avatars subdirectory. If the URL path exists within the avatars directory, ClipBucket will delete it. There is no check for path traversal sequences in the provided user input (stored in the DB as avatar_url) therefore the final $file variable could be tainted with path traversal sequences. This leads to file deletion outside of the intended scope of the avatars folder. This vulnerability is fixed in 5.5.1 - 237.

ClipBucket V5 provides open source video hosting with PHP. ClipBucket-v5 Version 5.5.1 Revision 199 and below is vulnerable to PHP Deserialization vulnerability. The vulnerability exists in upload/upload.php where the user supplied input via collection get parameter is directly provided to unserialize function. As a result, it is possible for an adversary to inject maliciously crafted PHP serialized object and utilize gadget chains to cause unexpected behaviors of the application. This vulnerability is fixed in 5.5.1 Revision 200.

ClipBucket V5 provides open source video hosting with PHP. ClipBucket-v5 Version 2.0 to Version 5.5.1 Revision 199 are vulnerable to PHP Deserialization vulnerability. The vulnerability exists in upload/photo_upload.php within the decode_key function. User inputs were supplied to this function without sanitization via collection GET parameter and photoIDS POST parameter respectively. The decode_key function invokes PHP unserialize function as defined in upload/includes/classes/photos.class.php. As a result, it is possible for an adversary to inject maliciously crafted PHP serialized object and utilize gadget chains to cause unexpected behaviors of the application. This vulnerability is fixed in 5.5.1 Revision 200.
