Описание
The Alertmanager in CNCF Cortex before 1.8.1 has a local file disclosure vulnerability when -experimental.alertmanager.enable-api is used. The HTTP basic auth password_file can be used as an attack vector to send any file content via a webhook. The alertmanager templates can be used as an attack vector to send any file content because the alertmanager can load any text file specified in the templates list.
A flaw was found in Cortex that may allow a local attacker to obtain sensitive information. This is due to an issue in the Alertmanager when -experimental.alertmanager.enable-api is used. By using a webhook to send file content, an attacker can load any text file specified in the templates list, obtain sensitive information, and use this information to launch further attacks against the affected system.
