Summary
A vulnerability in the MISP dashboard widgets allowed an authenticated user to manipulate field options, potentially disclosing user email addresses and other organization data even when disclosure was disabled in configuration.
Risk Assessment
The organization may be exposed to unauthorized access to sensitive user and organization data, leading to privacy breaches and loss of trust.
Recommendation
It is recommended to update to the latest version of MISP that includes security patches to ensure restricted fields are properly filtered and cannot be manipulated by low-privileged users.
Original NVD description (English source)
A vulnerability in the MISP dashboard widgets allowed an authenticated user to manipulate the fields option and influence which fields were returned by the New Users and New Organisations widgets. In some cases, requesting a field set that became empty after validation or redaction could cause the underlying query to fall back to returning unintended model fields. For the New Users widget, this could allow a non-site-admin user to obtain user e-mail addresses even when user e-mail disclosure was disabled by configuration. For the New Organisations widget, crafted field selection could similarly result in unintended organisation fields being included in the dashboard response. The issue was caused by applying field filtering and redaction in a way that could leave the selected field list empty. The patch ensures that the allowed field list is built safely, that restricted fields such as user e-mail addresses are removed before user-supplied field selection is processed, and that an empty field selection falls back only to the permitted default fields. Impact: An authenticated low-privileged user with access to the affected dashboard widgets may be able to disclose restricted user or organisation metadata, including user e-mail addresses depending on configuration.
