Short explanation
A vulnerability in the Kuadrant operator allows gateway policy bypasses via specially crafted HTTPRoute match values.
This vulnerability can lead to the bypassing of authentication and rate limiting controls, allowing requests to be forwarded to backend systems without security checks.
What should be done?
- Follow vendor advisory guidelines
- Review HTTPRoute configurations and permissions
Chain of evidence and sources
Kuadrant operator dahili WebAssembly aracı, HTTPRoute eşleşme alanlarındaki değerleri düzgün kaçamadığı için CEL koşul ifadesinde güvenlik açığı oluşur.
Özel olarak hazırlanmış path, header veya query eşleşme değerleri, ağ geçidi kimlik doğrulama ve hız sınırlama kontrollerinin atlanmasına neden olur.
Show the technical text from the sources
A flaw was found in the internal WebAssembly (WASM) shim used by the Kuadrant operator. When generating the CEL predicate that determines whether Gateway-level authentication and rate limiting should run, the shim does not correctly escape values from HTTPRoute match fields. A user who can create or modify an HTTPRoute attached to a shared Gateway can provide a crafted path, header, or query match value that causes the predicate to skip those checks. The request is still forwarded to the route’s backend.
