NewCVE-2024-53990 (opens in a new tab)How to fix?
Upgrade org.asynchttpclient:async-http-client to version 3.0.1 or higher.
Overview
org.asynchttpclient:async-http-client is a maven plugin for the Async Http Client (AHC) classes.
Affected versions of this package are vulnerable to Improper Authentication due to the CookieStore process in the RequestBuilderBase component, which replaces Cookies that were explicitly defined with any that have the same name from the cookie jar. An attacker can manipulate session management by replacing user cookies with others having the same name.
PoC
Add an auth Cookie to the CookieStore
Handle a different user's request where the same Cookie is provided as a passthrough, like a JWT, and attempt to use it by explicitly providing it.
Observe that the user's cookie in step 2 is passed as the Cookie in step 1.
