Ajaxeplorer before 5.0.1 allows remote attackers to execute arbitrary commands via shell metacharacters in the (1) archive_name 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" get_sess_id 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.
