CVSS 3.1
6.5 mediumCVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:NCVE-2022-23536
Medium (6.5) in linuxfoundation cortex. EPSS 0.8% chance of exploitation in the next 30 days. Fixed in github.com/cortexproject/cortex 1.13.2, 1.14.1.
Cortex provides multi-tenant, long term storage for Prometheus. A local file inclusion vulnerability exists in Cortex versions 1.13.0, 1.13.1 and 1.14.0, where a malicious actor could remotely read local files as a result of parsing maliciously crafted Alertmanager configurations when submitted to the Alertmanager Set Configuration API. Only users of the Alertmanager service where `-experimental.alertmanager.enable-api` or `enable_api: true` is configured are affected. Affected Cortex users are advised to upgrade to patched versions 1.13.2 or 1.14.1. However as a workaround, Cortex administrators may reject Alertmanager configurations containing the `api_key_file` setting in the `opsgenie_configs` section before sending to the Set Alertmanager Configuration API.
