ClipBucket version 2.6 and earlier contains a critical vulnerability in the ofcuploadimage.php script located at /adminarea/charts/ofc-library/. This endpoint allows unauthenticated users to upload arbitrary files, including executable PHP scripts. Once uploaded, the attacker can access the file via a predictable path and trigger remote code execution.

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/photoupload.php within the decodekey function. User inputs were supplied to this function without sanitization via collection GET parameter and photoIDS POST parameter respectively. The decodekey 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.

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 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. 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. Prior to version 5.5.3 - #129, the actions/progressvideo.php endpoint is vulnerable to blind SQL injection. Any unauthenticated user can exploit the ids parameter to execute SQL queries and exfiltrate sensitive data. This issue has been patched in version 5.5.3 - #129.

ClipBucket v5 is an open source video sharing platform. Prior to version 5.5.3 - #140, ClipBucket's Remote Play feature allows any authenticated user to add a video by importing an external URL as the source. Some shell commands are run with the URL as a parameter. The URL is concatenated directly into shell commands without escaping then executed, so any shell metacharacter in the URL is interpreted. This results in arbitrary command execution. This issue has been patched in version 5.5.3 - #140.

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 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 avatarurl 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 avatarurl) 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 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 ClipBucket version 5.5.2, a change to network.class.php causes the application to dynamically build the server URL from the incoming HTTP Host header when the configuration baseurl is not set. Because Host is a client-controlled header, an attacker can supply an arbitrary Host value. This allows an attacker to cause password-reset links (sent by forget.php) to be generated with the attacker’s domain. If a victim follows that link and enters their activation code on the attacker-controlled domain, the attacker can capture the code and use it to reset the victim’s password and take over the account. This issue has been patched in version 5.5.2#162.

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 - #132, any authenticated user who can upload videos can add multiple subtitles from different files and change their title (English, Spanish...). The POST /actions/subtitleedit.php request used to change their title includes a number parameter which is vulnerable to SQL Injection. A boolean-based blind SQL injection can be used to exfiltrate sensitive data. This issue has been patched in version 5.5.3 - #132.

ClipBucket v5 before 5.5.3-#182 contains a file upload vulnerability that allows authenticated users to achieve remote code execution by uploading a PHP file with valid image magic bytes through the photo upload endpoint. The FileUpload::manageFile() function in fileupload.class.php fails to update the file extension after MIME validation, allowing an attacker-controlled .php extension to persist on disk and execute as PHP via PHP-FPM when the uploaded file is retrieved.

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.

An issue in ClipBucket 5.5.0 and prior versions allows an unauthenticated attacker can exploit the plupload endpoint in photouploader.php to upload arbitrary files without any authentication, due to missing access controls in the upload handler

An issue in ClipBucket v5 v.5.5.2 allows an attacker to execute arbitrary code via the Authentication interface, login page endpoint and HTTP response security headers components

ClipBucket V5 provides open source video hosting with PHP. In version5.5.2 - #140 and earlier, a Blind SQL injection vulnerability exists in the Admin Area’s “/adminarea/loginasuser.php” file. Exploiting this vulnerability requires access privileges to the Admin Area.

ClipBucket v5 is an open source video sharing platform. Prior to version 5.5.2 #147, ClipBucket v5 is vulnerable to arbitrary PHP code execution. In /upload/adminarea/actions/updatelaunch.php, the "type" parameter from a POST request is embedded into PHP tags and executed. Proper sanitization is not performed, and by injecting malicious code an attacker can execute arbitrary PHP code. This allows an attacker to achieve RCE. This issue has been resolved in version 5.5.2 #147.

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.

ClipBucket v5 is an open source video sharing platform. In versions 5.5.2-#146 and below, the Manage Playlists feature is vulnerable to stored Cross-site Scripting (XSS),specifically in the Playlist Name field. An authenticated low-privileged user can create a playlist with a malicious name containing HTML/JavaScript code, which is rendered unescaped on playlist detail and listing pages. This results in arbitrary JavaScript execution in every viewer’s browser, including administrators. This issue is fixed in version 5.5.2-#147.

ClipBucket v5 is an open source video sharing platform. Prior to 5.5.3 - #122, there is a critical SQL Injection (SQLi) vulnerability in ClipBucket, exploitable through the type parameter on the authenticated admin endpoint adminarea/actionlogs.php. The endpoint adminarea/actionlogs.php reads $GET['type'], stores it in $resultarray['type'], and forwards it into fetchactionlogs(), where the value is concatenated directly into a SQL WHERE condition on actiontype without parameterization. This allows UNION-based SQL injection and direct data exfiltration from the database. This vulnerability is fixed in 5.5.3 - #122.

ClipBucket is a web-based video-sharing platform. In ClipBucket version 5.5.2 - #146 and earlier, the /adminarea/templateeditor.php endpoint is vulnerable to path traversal. The validation of the file-loading path is inadequate, allowing authenticated administrators to read and write arbitrary files outside the intended template directory by inserting path traversal sequences into the folder parameter. An attacker with administrator privileges can exploit this vulnerability to read sensitive files such as /etc/passwd and modify writable files on the system, potentially leading to sensitive information disclosure and compromise of the application or server. This issue is fixed in version 5.5.2 - #147.

ClipBucket v5 is an open source video sharing platform. Versions 5.5.2 - #151 and below allow authenticated administrators with plugin management privileges to execute arbitrary SQL commands against the database through its ClipBucket Custom Fields plugin. The vulnerabilities require the Custom Fields plugin to be installed and accessible, and can only be exploited by users with administrative access to the plugin interface. This issue is fixed in version 5.5.2 - #.

ClipBucket v5 is an open source video sharing platform. Prior to version 5.5.2 - #164, an authorization bypass vulnerability in the AJAX flagging system allows any unauthenticated user to flag any content (users, videos, photos, collections) on the platform. This can lead to mass flagging attacks, content disruption, and moderation system abuse. This issue has been patched in version 5.5.2 - #164.

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 version 5.5.3 - #133, a normal authenticated user can edit another user's video subtitles because of a lack of authorization. They can upload subtitles, edit their name or delete them. This issue has been patched in version 5.5.3 - #133.

ClipBucket v5 through 5.5.3 contains a blind SQL injection vulnerability that allows authenticated users to extract arbitrary data from the database by submitting the checkphoto parameter as an array to bypass the cleanrequests() sanitization function in ClipBucket.class.php. Attackers can pass unsanitized array elements through the bulk deletion handler in managephotos.php to photoexists() in photos.class.php, where non-numeric values are interpolated directly into a SQL query, enabling time-based blind SQL injection to retrieve credential hashes and other sensitive data.

ClipBucket v5 through 5.5.3 contains a blind SQL injection vulnerability that allows authenticated users to extract arbitrary database contents by submitting the msgid parameter as an array to bypass the cleanrequests() sanitization function in ClipBucket.class.php. Attackers can pass unsanitized array elements through the deletion handler in privatemessage.php into cbpm::deletemsg(), which interpolates the unescaped message ID directly into a SQL query string, enabling time-based blind SQL injection to retrieve all user credential hashes and email addresses.
