Directory traversal in the Copy, Move, and Delete features in Pydio Cells 2.2.9 allows remote authenticated users to enumerate personal files (or Cells files belonging to any user) via the nodes parameter (for Copy and Move) or via the Path parameter (for Delete).

Broken access control for user creation in Pydio Cells 2.2.9 allows remote anonymous users to create standard users via the profile parameter. (In addition, such users can be granted several admin permissions via the Roles parameter.)

Directory traversal in the Compress feature in Pydio Cells 2.2.9 allows remote authenticated users to overwrite personal files, or Cells files belonging to any user, via the format parameter.

A problem was found in Pydio Core before 8.2.4 and Pydio Enterprise before 8.2.4. A PHP object injection is present in the page plugins/uploader.http/HttpDownload.php. An authenticated user with basic privileges can inject objects and achieve remote code execution.

A problem was found in Pydio Core before 8.2.4 and Pydio Enterprise before 8.2.4. A PHP object injection is present in the page plugins/core.access/src/RecycleBinManager.php. An authenticated user with basic privileges can inject objects and achieve remote code execution.

Ajaxeplorer before 5.0.1 allows remote attackers to execute arbitrary commands via shell metacharacters in the (1) archivename parameter to the Power FS module (plugins/action.powerfs/class.PowerFSController.php), a (2) file name to the getTrustSizeOnFileSystem function in the File System (Standard) module (plugins/access.fs/class.fsAccessWrapper.php), or the (3) revision parameter to the Subversion Repository module (plugins/meta.svn/class.SvnManager.php).

Pydio 6.0.8 allows Authenticated SSRF during a Remote Link Feature download. An attacker can specify an intranet address in the file parameter to index.php, when sending a file to a remote server, as demonstrated by the file=http%3A%2F%2F192.168.1.2 substring.

Pydio 6.0.8 mishandles error reporting when a directory allows unauthenticated uploads, and the remote-upload option is used with the http://localhost:22 URL. The attacker can obtain sensitive information such as the name of the user who created that directory and other internal server information.

An issue was discovered in proxy.php in pydio-core in Pydio through 8.2.2. Through an unauthenticated request, it possible to evaluate malicious PHP code by placing it on the fourth line of a .php file, as demonstrated by a PoC.php created by the guest account, with execution via a proxy.php?hash=../../../../../var/lib/pydio/data/personal/guest/PoC.php request. This is related to plugins/action.share/src/Store/ShareStore.php.

It is possible for an attacker with regular user access to the web application of Pydio through 8.2.2 to trick an administrator user into opening a link shared through the application, that in turn opens a shared file that contains JavaScript code (that is executed in the context of the victim user to obtain sensitive information such as session identifiers and perform actions on behalf of him/her).

The ImageMagick plugin that is installed by default in Pydio through 8.2.2 does not perform the appropriate validation and sanitization of user supplied input in the plugin's configuration options, allowing arbitrary shell commands to be entered that result in command execution on the underlying operating system, with the privileges of the local user running the web server. The attacker must be authenticated into the application with an administrator user account in order to be able to edit the affected plugin configuration.

A stored XSS vulnerability exists in the web application of Pydio through 8.2.2 that can be exploited by levering the file upload and file preview features of the application. An authenticated attacker can upload an HTML file containing JavaScript code and afterwards a file preview URL can be used to access the uploaded file. If a malicious user shares an uploaded HTML file containing JavaScript code with another user of the application, and tricks an authenticated victim into accessing a URL that results in the HTML code being interpreted by the web browser, then the included JavaScript code is executed under the context of the victim user session.

An unauthenticated attacker can obtain information about the Pydio 8.2.2 configuration including session timeout, libraries, and license information.

The "action" getsessid in the web application of Pydio through 8.2.2 discloses the session cookie value in the response body, enabling scripts to get access to its value. This identifier can be reused by an attacker to impersonate a user and perform actions on behalf of him/her (if the session is still active).

In Pydio before 8.2.2, an attack is possible via PHP Object Injection because a user is allowed to use the $phpserial$a:0:{} syntax to store a preference. An attacker either needs a "public link" of a file, or access to any unprivileged user account for creation of such a link.

Pydio 4.2.1 through 8.2.1 has an authenticated remote code execution vulnerability in which an attacker with administrator access to the web application can execute arbitrary code on the underlying system via Command Injection.

Pydio version 8.2.0 and earlier contains a Server-Side Request Forgery (SSRF) vulnerability in plugins/action.updater/UpgradeManager.php Line: 154, getUpgradePath($url) that can result in an authenticated admin users requesting arbitrary URL's, pivoting requests through the server. This attack appears to be exploitable via the attacker gaining access to an administrative account, enters a URL into Upgrade Engine, and reloads the page or presses "Check Now". This vulnerability appears to have been fixed in 8.2.1.

Pydio (formerly AjaXplorer) before 6.0.7 allows remote attackers to execute arbitrary commands via unspecified vectors, aka "Pydio OS Command Injection Vulnerabilities."

Multiple cross-site scripting (XSS) vulnerabilities in Pydio (formerly AjaXplorer) before 6.0.7 allow remote attackers to inject arbitrary web script or HTML via unspecified vectors, aka "Pydio XSS Vulnerabilities."

Unrestricted file upload vulnerability in plugins/editor.zoho/agent/savezoho.php in the Zoho plugin in Pydio (formerly AjaXplorer) before 5.0.4 allows remote attackers to execute arbitrary code by uploading an executable file, and then accessing this file at a location specified by the format parameter of a move operation.
