LORIS media module vulnerable to remote code execution

LORIS (Longitudinal Online Research and Imaging System) is a self-hosted web application that provides data- and project-management for neuroimaging research. Prior to versions 26.0.5, 27.0.2, and 28.0.0, an authenticated user with sufficient privileges can exploit a path traversal vulnerability to upload a malicious file to an arbitrary location on the server. Once uploaded, the file can be used to achieve remote code execution (RCE). An attacker must be authenticated and have the appropriate permissions to exploit this issue. If the server is configured as read-only, remote code execution (RCE) is not possible; however, the malicious file upload may still be achievable. This problem is fixed in LORIS v26.0.5 and above, v27.0.2 and above, and v28.0.0 and above. As a workaround, LORIS administrators can disable the media module if it is not being used.

LORIS vulnerable to path traversal in electrophysiology_browser

LORIS (Longitudinal Online Research and Imaging System) is a self-hosted web application that provides data- and project-management for neuroimaging research. Starting in version 24.0.0 and prior to versions 26.0.5, 27.0.2, and 28.0.0, an authenticated user with the appropriate authorization can read configuration files on the server by exploiting a path traversal vulnerability. Some of these files contain hard-coded credentials. The vulnerability allows an attacker to read configuration files containing hard-coded credentials. The attacker could then authenticate to the database or other services if those credentials are reused. The attacker must be authenticated and have the required permissions. However, the vulnerability is easy to exploit and the application source code is public. This problem is fixed in LORIS v26.0.5 and v27.0.2 and above, and v28.0.0 and above. As a workaround, the electrophysiogy_browser in LORIS can be disabled by an administrator using the module manager.
