Vulnerability Title
L7 policy bypass via unnormalized HTTP path matching
Vulnerability Description
Calico's Application Layer Policy (disabled by default), which enforces HTTP rules through Dikastes, fails to perform URL path normalization. As a result, HTTP requests using path-traversal segments, encoded slashes, or repeated slashes are not correctly evaluated by Prefix path rules. Dikastes authorizes the request under the permitted prefix while the downstream workload or a fronting proxy normalizes the path and serves the restricted endpoint. An attacker with network access and no special RBAC can potentially reach HTTP endpoints the policy was intended to restrict.

对路径名的限制不恰当(路径遍历)
Vulnerability Title
Tigera Calico 路径遍历漏洞
Vulnerability Description
Tigera Calico是美国Tigera公司开源的一套针对容器、虚拟机和主机工作负载的开源网络安全解决方案。 Tigera Calico存在路径遍历漏洞,该漏洞源于Application Layer Policy未进行URL路径规范化,导致前缀路径规则无法正确评估包含路径遍历段、编码斜杠或重复斜杠的HTTP请求,Dikastes在允许前缀下授权请求,而下游工作负载或前端代理会规范化路径并服务受限制的端点,攻击者可能访问策略本应限制的HTTP端点。
