CVE-2024-7207 (opens in a new tab)How to fix?
Upgrade envoyproxy/envoy to version 1.28.7, 1.29.9, 1.30.6, 1.31.2 or higher.
Overview
Affected versions of this package are vulnerable to Improper Input Validation through the manipulation of HTTP headers. An attacker can forge requests to internal-only services or arbitrary external systems by manipulating headers in pass-through routes used for the ingress gateway. This is only exploitable if the internal_address_config range for envoy is not set to 0.0.0.0/32.
Note:
This is a regression of the fix for CVE-2023-27487
Workaround
This vulnerability can be mitigated by setting the internal_address_config range for envoy to 0.0.0.0/32.
