Uncontrolled Recursion in io.undertow:undertow-core

CVE-2024-5971

  • io.undertow:undertow-core
  • io.undertow:undertow-dist
  • io.undertow:undertow-parent
High
7.5/10

Summary

A vulnerability was found in the undertow-core, where the chunked response hangs after the body was flushed. The response headers and body were sent, but the client would continue waiting as Undertow did not send the expected "0\r\n" termination of the chunked response. This results in uncontrolled resource consumption, leaving the server side to a Denial of Service (DOS) attack. This happens only with Java 17 TLSv1.3 scenarios. This vulnerability affects io.undertow:undertow-core package versions 1.2.0.Beta6 through 2.3.14.Final.
