Mô tả

Impact

A local file inclusion vulnerability exists in Cortex versions v1.13.0, v1.13.1 and v1.14.0, 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 Cortex Alertmanager service using -experimental.alertmanager.enable-api or enable_api: true are affected.

Specific Go Packages Affected

github.com/cortexproject/cortex/pkg/alertmanager

Patches

Affected Cortex users are advised to upgrade to versions 1.13.2 or 1.14.1.

Workarounds

Patching is ultimately advised. Using out-of-bound validation, Cortex administrators may reject Alertmanager configurations containing the api_key_file setting in the opsgenie_configs section and opsgenie_api_key_file in the global section before sending to the Set Alertmanager Configuration API as a workaround.

Mô tả của NVD

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.
