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.
github.com/cortexproject/cortex/pkg/alertmanager
Affected Cortex users are advised to upgrade to versions 1.13.2 or 1.14.1.
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.
