Apache Camel 平台 HTTP 组件存在“大小写敏感性处理不当”的漏洞。 受影响的版本范围:Apache Camel 4.0.0 至 4.18.5(不含 4.18.5),以及 4.19.0 至 4.22.1(不含 4.22.1)。 该漏洞源于:用于防止请求头被反射到响应中的防护机制,在比较请求头名称时采用了大小写敏感的方式,而 HTTP 请求头名称本身是大小写不敏感的。因此,攻击者只需改变请求头名称的大小写,即可绕过该抑制机制。在 HTTP/2 协议下,该问题变得更为严重:由于协议强制要求传输层中的请求头

Vulnerability Title
Apache Camel: Camel-Platform-HTTP Request-Header Echo Suppression Bypassed by Header-Name Casing
来源: CVE Program / CVE List V5
Vulnerability Description
Improper Handling of Case Sensitivity vulnerability in Apache Camel Platform HTTP component. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1. The guard that prevents a request header being reflected into the response compared header names case sensitively, while HTTP header names are case insensitive. A caller could therefore defeat the suppression simply by varying the case of the header name. HTTP/2 makes the problem unconditional rather than optional: the protocol requires header names to be lowercase on the wire, so the comparison never matched and the suppression was inert for every request on an HTTP/2 connection. The consequence is that content the caller chose is echoed back in the response, which is the basis for response-splitting and cache-poisoning style attacks against whatever sits in front of the Camel endpoint. 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. Request header names are now compared case insensitively, so the suppression holds regardless of casing and works under HTTP/2. For deployments that cannot upgrade immediately, strip the headers in question in front of the Camel endpoint, or remove them from the response in the route rather than relying on the built-in suppression.
