Jetty 9.4.27 < 9.4.30 Buffer Overflow

critical Web App Scanning Plugin ID 113003

Synopsis

Jetty 9.4.27 < 9.4.30 Buffer Overflow

Description

The version of Jetty installed on the remote host when handling too large response headers throws an exception to produce an HTTP 431 error. When this happens, the ByteBuffer containing the HTTP response headers is released back to the ByteBufferPool twice. Because of this double release, two threads can acquire the same ByteBuffer from the pool and potentially leak sensitive data between the two clients. Note that the scanner has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Jetty version 9.4.30 or later.
