Lifecycle Timeline
3Description
LORIS (Longitudinal Online Research and Imaging System) is a self-hosted web application that provides data- and project-management for neuroimaging research. From 20.0.0 to before 27.0.3 and 28.0.1, an endpoint in the publication module was incorrectly trusting the baseURL submitted by a user's POST request rather than the internal LORIS value. This could result in a theoretical attacker with publication module access forging an email to an external domain under the attacker's control which appeared to come from LORIS. This vulnerability is fixed in 27.0.3 and 28.0.1.
Analysis
LORIS (Longitudinal Online Research and Imaging System) versions 20.0.0 through 27.0.2 and 28.0.0 allow authenticated users with publication module access to forge emails appearing to originate from LORIS by submitting a malicious baseURL parameter in POST requests, enabling email spoofing attacks against external recipients. The vulnerability requires user interaction (email recipient click) and publication module privileges but could facilitate social engineering or phishing campaigns. …
