Apache NiFi: Improper Neutralization of Input in Parameter Description (CVE-2024-45477)
Description
Apache NiFi 1.10.0 through 1.27.0 support a description field for Parameters in a Parameter Context configuration that is vulnerable to cross-site scripting. An authenticated user, authorized to configure a Parameter Context, can enter arbitrary JavaScript code, which the client browser will execute within the session context of the authenticated user. Upgrading to Apache NiFi 1.28.0 or higher is the recommended mitigation.

Technical Analysis
Apache NiFi versions from 1.10.0 up to but not including 1.28.0 have an XSS vulnerability in the Parameter Context description field. This flaw allows an authenticated and authorized user to insert malicious JavaScript code that executes in the context of other authenticated users' browsers. The vulnerability arises from improper neutralization of input in the parameter description field. The recommended remediation is to upgrade to Apache NiFi 1.28.0 or higher.
Potential Impact
An attacker with authenticated access and permission to configure Parameter Contexts can inject JavaScript code that executes in the browser of an authenticated user, potentially leading to session hijacking or other client-side attacks within the NiFi UI session. This impacts the confidentiality and integrity of user sessions but requires prior authentication and authorization.
Mitigation Recommendations
A patch is available in Apache NiFi version 1.28.0 and later. Upgrading to version 1.28.0 or higher fully mitigates this vulnerability. No additional mitigation steps are indicated by the vendor advisory.
