优先检查厂商安全公告和参考链接中的修复版本;无法立即升级时,限制受影响服务暴露并加强监测。

Apache Camel Netty HTTP 组件中存在因大小写处理不当导致的安全漏洞。 受影响版本: Apache Camel 4.0.0 至 4.18.4(含) Apache Camel 4.19.0 至 4.22.0(含) 问题描述: camel-netty-http 安全约束在比较请求路径与配置的上下文路径时,采用了区分大小写的匹配方式;而负责将请求分发到目标端点的路由逻辑却未遵循相同的大小写规则。因此,对于任何大小写与配置值不一致的路径,这两处比较会产生不一致的结果。外部攻击者可通过修改路径段中某个字符

Vulnerability Title
Apache Camel: Camel-Netty-HTTP Security Constraint Bypass via Case-Sensitive Context-Path Matching
来源: CVE Program / CVE List V5
Vulnerability Description
Improper Handling of Case Sensitivity vulnerability in Apache Camel Netty HTTP component. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1. The camel-netty-http security constraint compared the request path against the configured context path using a case-sensitive match, while the routing that dispatches the request to the endpoint did not apply the same rule. The two comparisons therefore disagreed for any path whose case differed from the configured value. An external caller could alter the case of a character in a path segment so that the security constraint no longer recognised the path as protected, while the request still dispatched to the same endpoint. The result is that the constraint is skipped and the protected route is reached without satisfying it. No credential, prior access or special configuration is required beyond being able to send a request to the consumer. 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 constraint now matches the request path with the same case rules the dispatch uses, so the two can no longer disagree. For deployments that cannot upgrade immediately, place the authorization decision in front of the Camel consumer, for example in a reverse proxy that normalises the request path before forwarding.
