HTTP Request Smuggling

  • Vulnerable module: io.netty:netty-codec-http
  • Introduced through: io.netty:netty-all@4.1.86.Final

Detailed paths

  • Introduced through: albahrani/pi4j-rest-sysinfo@albahrani/pi4j-rest-sysinfo#f12b589dff6024907f6c2c8da334e6002485bff6 › io.netty:netty-all@4.1.86.Final › io.netty:netty-codec-http@4.1.86.Final
    Remediation: Upgrade to io.netty:netty-all@4.1.125.Final.

Overview

io.netty:netty-codec-http is a network application framework for rapid development of maintainable high performance protocol servers & clients.

Affected versions of this package are vulnerable to HTTP Request Smuggling via the parsing of chunk extensions in HTTP/1.1 messages with chunked encoding. An attacker can bypass HTTP request boundaries by sending specially crafted HTTP requests that exploit differences in how standalone newline characters are parsed between reverse proxies and the backend, potentially allowing them to smuggle additional requests.

Remediation

Upgrade io.netty:netty-codec-http to version 4.1.125.Final, 4.2.5.Final or higher.

Improper Handling of Highly Compressed Data (Data Amplification)

  • Vulnerable module: io.netty:netty-codec-http
  • Introduced through: io.netty:netty-all@4.1.86.Final

Detailed paths

  • Introduced through: albahrani/pi4j-rest-sysinfo@albahrani/pi4j-rest-sysinfo#f12b589dff6024907f6c2c8da334e6002485bff6 › io.netty:netty-all@4.1.86.Final › io.netty:netty-codec-http@4.1.86.Final
    Remediation: Upgrade to io.netty:netty-all@4.1.125.Final.

Overview

io.netty:netty-codec-http is a network application framework for rapid development of maintainable high performance protocol servers & clients.

Affected versions of this package are vulnerable to Improper Handling of Highly Compressed Data (Data Amplification) via the BrotliDecoder.decompress function, which has no limit on how often it calls pull, decompressing data 64K bytes at a time. An attacker can exhaust system memory and cause application downtime by submitting specially crafted compressed input that triggers excessive buffer allocations.

Allocation of Resources Without Limits or Throttling

  • Vulnerable module: io.netty:netty-codec-http2
  • Introduced through: io.netty:netty-all@4.1.86.Final

Detailed paths

  • Introduced through: albahrani/pi4j-rest-sysinfo@albahrani/pi4j-rest-sysinfo#f12b589dff6024907f6c2c8da334e6002485bff6 › io.netty:netty-all@4.1.86.Final › io.netty:netty-codec-http2@4.1.86.Final
    Remediation: Upgrade to io.netty:netty-all@4.1.124.Final.

Overview

io.netty:netty-codec-http2 is a HTTP2 sub package for the netty library, an event-driven asynchronous network application framework.

Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling through the improper handling of concurrently active streams per connection. An attacker can cause resource exhaustion and disrupt service availability by rapidly sending crafted frames, such as WINDOW_UPDATE, HEADERS, or PRIORITY, that manipulate the server's stream reset logic, leading to unbounded concurrent stream processing.

Remediation

Upgrade io.netty:netty-codec-http2 to version 4.1.124.Final, 4.2.4.Final or higher.

    Remediation: Upgrade to io.netty:netty-all@4.1.100.Final.

Overview

io.netty:netty-codec-http2 is a HTTP2 sub package for the netty library, an event-driven asynchronous network application framework.

Affected versions of this package are vulnerable to Denial of Service (DoS) in the implementation of the HTTP/2 protocol. An attacker can cause a denial of service (including via DDoS) by rapidly resetting many streams through request cancellation.

    Remediation: Upgrade to io.netty:netty-all@4.1.108.Final.

Overview

io.netty:netty-codec-http is a network application framework for rapid development of maintainable high performance protocol servers & clients.

Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling due to the accumulation of data in the HttpPostRequestDecoder. The decoder cumulates bytes in the undecodedChunk buffer until it can decode a field, allowing for data to accumulate without limits.

An attacker can cause a denial of service by sending a chunked post consisting of many small fields that will be accumulated in the bodyListHttpData list.

Remediation

Upgrade io.netty:netty-codec-http to version 4.1.108.Final or higher.
