CVE-2019-9901
6.5
CVSS:3.0/AC:H/AV:N/A:L/C:L/I:L/PR:N/S:C/UI:N
Summary
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.
