CVE-2024-7885 (opens in a new tab)How to fix?
Upgrade io.undertow:undertow-core to version 2.2.36.Final, 2.3.17.Final or higher.
Overview
io.undertow:undertow-core is a Java web server based on non-blocking IO.
Affected versions of this package are vulnerable to Race Condition due to the reuse of the StringBuilder instance in the ProxyProtocolReadListener across multiple requests. An attacker can access data from previous requests or responses by exploiting the shared usage of the StringBuilder.
This vulnerability primarily results in errors and connection termination but creates a risk of data leakage in multi-request environments.
