Upgrade org.apache.camel:camel-as2-api to version 4.18.5, 4.22.1 or higher.
Overview
Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) via the asynchronous MDN delivery process in the camel-as2 component. An attacker can make the AS2 receiver connect to attacker-chosen or internally reachable hosts by sending a message with a malicious Receipt-Delivery-Option header; if MDN credentials are configured, the receiver also sends them to the chosen host.
Workarounds
- Restrict outbound connectivity from the AS2 receiver to partner endpoints that legitimately receive MDNs, preventing sender-supplied destinations from reaching other hosts.
- Do not attach MDN-delivery credentials that are valid for hosts other than those authorized partner endpoints, limiting credential exposure to an attacker-chosen destination.
