What to do

Solution (from the CVE record)

The fix ensures that the redacted and cli_only flags declared by a module in its own setting definition are preserved when the server rebuilds the setting for API exposure. By carrying these flags through to the final setting object, the existing enforcement logic (which checks these flags before serving values or accepting edits) now correctly applies to module-supplied settings, preventing disclosure of redacted values and blocking API-based modification of CLI-only settings.

About this vulnerability

MISP contains a vulnerability in the handling of module plugin settings. When the server rebuilds module-supplied settings for API consumption, it drops the redacted and cli_only flags that a module declares in its own configuration metadata. As a result: - A module that marks a setting (such as an API key) as redacted still has its value returned in full by the servers/getSetting and servers/s…

Description

MISP Module Settings Expose Redacted Values and Allow API Modification of CLI-Only Settings

MISP contains a vulnerability in the handling of module plugin settings. When the server rebuilds module-supplied settings for API consumption, it drops the redacted and cli_only flags that a module declares in its own configuration metadata. As a result: - A module that marks a setting (such as an API key) as redacted still has its value returned in full by the servers/getSetting and servers/serverSettingsEdit endpoints, exposing sensitive credentials to any authenticated user who can read server settings. - A module that marks a setting as cli_only (intended to be editable only via the command-line interface) can still be modified through the web API, bypassing the intended access restriction. An authenticated user with access to server settings can therefore read sensitive module credentials and modify settings that the module author intended to restrict to CLI-only access. Affected: <2.5.48
