CVE-2019-9901
CRITICAL10.0EPSS 0.09%EnvoyProxy Envoy Missing HTTP URL path normalization
發布日:2022/5/24修改日:2026/3/13
描述
Envoy 1.9.0 and before does not normalize HTTP URL paths. A remote attacker may craft a relative path, e.g., `something/../admin`, to bypass access control, e.g., a block on `/admin`. A backend server could then interpret the non-normalized path and provide an attacker access beyond the scope provided for by the access control policy.
