- Fix
0.7.2- Upgrade org.apache.nifi:nifi to this version or later
Description
In Apache NiFi before 0.7.2 and 1.x before 1.1.2 in a cluster environment, the proxy chain serialization/deserialization is vulnerable to an injection attack where a carefully crafted username could impersonate another user and gain their permissions on a replicated request to another node.
Affected versions
Maven
| Package | Vulnerable | Fixed in |
|---|---|---|
| org.apache.nifi:nifi | < 0.7.2 |
0.7.2 |
| org.apache.nifi:nifi | >= 1.0.0, < 1.1.2 |
1.1.2 |
How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.

Weakness
CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')
The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
How to prevent it
- Requirements: Programming languages and supporting technologies might be chosen which are not subject to these issues.
- Implementation: Utilize an appropriate mix of allowlist and denylist parsing to filter control-plane syntax from all input.
