A substantial-scale unauthenticated scraping of publicly out there and non-secured endpoints from more mature variations of Prometheus party checking and alerting answer could be leveraged to inadvertently leak sensitive information and facts, according to the most recent exploration.
“Thanks to the actuality that authentication and encryption aid is relatively new, lots of organizations that use Prometheus haven’t but enabled these options and so lots of Prometheus endpoints are totally exposed to the Internet (e.g. endpoints that run earlier versions), leaking metric and label dat,” JFrog researchers Andrey Polkovnychenko and Shachar Menashe mentioned in a report.
Prometheus is an open up-supply system monitoring and alerting toolkit made use of to accumulate and procedure metrics from different endpoints, together with enabling quick observation of software metrics these as memory use, network utilization, and application-certain described metrics, these kinds of as the number of unsuccessful logins to a web software. Assistance for Transportation Layer Security (TLS) and primary authentication was released with model 2.24. unveiled on January 6, 2021.
The conclusions occur from a systematic sweep of publicly-uncovered Prometheus endpoints, which were being available on the Internet without requiring any authentication, with the metrics found exposing software program variations and host names, which the researchers reported could be weaponized by attackers to conduct reconnaissance of a concentrate on setting right before exploiting a individual server or for submit-exploitation techniques like lateral motion.
Some of the endpoints and the information and facts disclosed are as follows –
- /api/v1/status/config – Leakage of usernames and passwords presented in URL strings from the loaded YAML configuration file
- /api/v1/targets – Leakage of metadata labels, together with natural environment variables as properly as person and device names, extra to concentrate on equipment addresses
- /api/v1/status/flags – Leakage of usernames when delivering a entire route to the YAML configuration file
Even extra concerningly, an attacker can use the “/api/v1/position/flags” endpoint to query the status of two administration interfaces — “web.help-admin-api” and “web.help-lifecycle” — and if found manually enabled, exploit them to delete all saved metrics and worse, shut down the monitoring server. It is really value noting the two endpoints are disabled by default for security causes as of Prometheus 2..
JFrog reported it discovered about 15% of the Internet-experiencing Prometheus endpoints had the API administration environment enabled, and 4% had databases management turned on. A full of about 27,000 hosts have been identified via a lookup on IoT search engine Shodan.
In addition to recommending businesses to “query the endpoints […] to assist verify if sensitive info could have been exposed,” the scientists noted that “state-of-the-art customers demanding more robust authentication or encryption than what is actually furnished by Prometheus, can also set up a independent network entity to take care of the security layer.”
