ClipBucket 5.5.2 is affected by an improper access control issue where the product is shipped or deployed with hardcoded default administrative credentials. An unauthenticated remote attacker can log in to the administrative panel using these default credentials, resulting in full administrative control of the application.

ClipBucket v5 is an open source video sharing platform. An authenticated time-based blind SQL injection vulnerability exists in ClipBucket prior to 5.5.3 #80 within the actions/ajax.php endpoint. Due to insufficient input sanitization of the userid parameter, an authenticated attacker can execute arbitrary SQL queries, leading to full database disclosure and potential administrative account takeover. Version 5.5.3 #80 fixes the issue.

ClipBucket v5 is an open source video sharing platform. Prior to version 5.5.3 #59, a normal authenticated user can store the XSS payload. The payload is triggered by administrator. Version 5.5.3 #59 fixes the issue.

ClipBucket v5 is an open source video sharing platform. Prior to version 5.5.3 #59, collection item operations are vulnerable to authorization flaws, allowing a normal authenticated user to modify another user’s collection items. This affects both add item (/actions/addtocollection.php) due to missing authorization checks and delete item (/managecollections.php?mode=manageitems...) due to a broken ownership check in removeItemFromCollection(). As a result, attackers can insert and remove items from collections they do not own. Version 5.5.3 #59 fixes the issue.

ClipBucket v5 is an open source video sharing platform. Prior to 5.5.3 - #40, a Time-of-Check to Time-of-Use (TOCTOU) race condition vulnerability exists in ClipBucket's avatar and background image upload functionality. The application moves uploaded files to a web-accessible location before validating them, creating a window where an attacker can execute arbitrary PHP code before the file is deleted. The uploaded file was moved to a web-accessible path via moveuploadedfile(), then validated via ValidateImage(). If validation failed, the file was deleted via @unlink(). This vulnerability is fixed in 5.5.3 - #40.

ClipBucket v5 is an open source video sharing platform. Prior to 5.5.3 - #45, in Clip Bucket V5, The Remote Play allows creating video entries that reference external video URLs without uploading the video files to the server. However, by specifying an internal network host in the video URL, an SSRF can be triggered, causing GET requests to be sent to internal servers. An attacker can exploit this to scan the internal network. Even a regular (non-privileged) user can carry out the attack.

ClipBucket v5 is an open source video sharing platform. Versions 5.5.2-#187 and below allow an attacker to perform Blind SQL Injection through the add comment section within a channel. When adding a comment within a channel, there is a POST request to the /actions/ajax.php endpoint. The objid parameter within the POST request to /actions/ajax.php is then used within the userexists function of the upload/includes/classes/user.class. php file as the $id parameter. It is then used within the count function of the upload/includes/classes/db.class. php file. The $id parameter is concatenated into the query without validation or sanitization, and a user-supplied input like 1' or 1=1-- - can be used to trigger the injection. This issue does not have a fix at the time of publication.

ClipBucket v5 is an open source video sharing platform. In versions 5.5.2 - #156 and below, an authenticated regular user can create a photo collection whose Collection Name contains HTML/JavaScript payloads, which making ClipBucket’s Manage Photos feature vulnerable to Stored XSS. The payload is rendered unsafely in the Admin → Manage Photos interface, causing it to execute in the administrator’s browser, therefore allowing an attacker to target administrators and perform actions with elevated privileges. This issue is fixed in version 5.5.2 - #157.

ClipBucket v5 is an open source video sharing platform. In versions 5.5.2-#146 and below, the Manage Photos feature is vulnerable to stored Cross-site Scripting (XSS). An authenticated regular user can upload a photo with a malicious Photo Title containing HTML/JavaScript code. While the payload does not execute in the user-facing photo gallery or detail pages, it is rendered unsafely in the Admin → Manage Photos section, resulting in JavaScript execution in the administrator’s browser. This issue is fixed in version 5.5.2-#147.
