Affected: CleanStart: apache-nifi
Multiple security vulnerabilities affect the apache-nifi package. yawkat LZ4 Java provides LZ4 compression for Java. See references for individual vulnerability details.
Netty is a network application framework for development of protocol servers and clients. Versions 4.2.0.Final through 4.2.15.Final and 4.1.0.Final through 4.1.135.Final, are vulnerable to security control bypass during the origin evaluation process. CorsHandler provides a shortCircuit() configuration designed to reject unauthorized cross-origin requests immediately, acting as a security control before requests reach the application. However, due to a logical operator error in the origin evaluation process, this protection can be entirely bypassed. An attacker can bypass the short-circuit mechanism by sending a request with an Origin: null header. This failure forwards unauthorized requests to the backend application, bypassing intended access controls. This issue is fixed in versions 4.1.136.Final and 4.2.16.Final.
Affected: Maven: io.netty:netty-codec-http
### Summary Netty's CorsHandler provides a `shortCircuit()` configuration designed to reject unauthorized cross-origin requests immediately, acting as a security control before requests reach the application. However, due to a logical operator error in the origin evaluation process, this protection can be entirely bypassed. An attacker can bypass the short-circuit mechanism by sending a request with an `Origin: null` header. This failure forwards unauthorized requests to the backend application, bypassing intended access controls.
### Details In `io.netty.handler.codec.http.cors.CorsHandler#channelRead`, the short-circuit logic relies on the configuration returned by `getForOrigin(origin)` to determine if an origin is authorized. If `getForOrigin` returns a configuration object, the short-circuit check `(!(origin == null || config != null))` is bypassed, and the request proceeds to the backend.
The vulnerability is located in the `getForOrigin` method:
```java if (corsConfig.isNullOriginAllowed() || NULL_ORIGIN.equals(requestOrigin)) { return corsConfig; } ```
If an attacker sends `Origin: null`, `NULL_ORIGIN.equals(requestOrigin)` evaluates to true. The method returns the configuration object regardless of whether `isNullOriginAllowed()` was configured by the developer. The short-circuit is bypassed.
### Impact Applications relying on CorsHandler's short-circuit feature to prevent unauthorized cross-origin requests from reaching…
