Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Apache Camel AS2 组件中存在服务端请求伪造（SSRF）漏洞。 该漏洞影响以下版本的 Apache Camel： 4.0.0 至 4.18.5（不含 4.18.5） 4.19.0 至 4.22.1（不含 4.22.1） 在 AS2 协议中，消息发送方可以请求将消息处置通知（Message Disposition Notification, MDN）异步返回到其指定的地址。camel-as2 组件直接从传入消息中获取该地址，并将其用作出站回执的目标，而未根据部署配置对该地址施加任何限制。因此，远程合作伙

Vulnerability Title
Apache Camel: Camel-AS2 Server-Side Request Forgery and Credential Disclosure via Asynchronous MDN Delivery Address
Source: CVE Program / CVE List V5
Vulnerability Description
Server-Side Request Forgery (SSRF) vulnerability in Apache Camel AS2 component. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1. In the AS2 protocol the sender of a message may request that the Message Disposition Notification be returned asynchronously to an address the sender supplies. camel-as2 took that address from the inbound message and used it as the destination for the outgoing receipt without constraining it to anything the deployment had configured. A remote partner therefore chose the host the Camel instance would connect to when delivering the MDN. That gives server-side request forgery from the position of the AS2 receiver, including reaching hosts that are only routable from inside the deployment's network, and where the outbound connection carries credentials configured for MDN delivery those credentials are presented to the attacker-chosen destination. Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. Users on the 4.22.x LTS releases stream should upgrade to 4.22.1. The asynchronous MDN destination is now constrained rather than taken verbatim from the inbound message. For deployments that cannot upgrade immediately, restrict outbound connectivity from the AS2 receiver to the partner endpoints it legitimately delivers receipts to, and do not attach credentials to MDN delivery that are valid for any host other than those partners.
