Vulnerability Title
Arbitrary redirects under /new endpoint
来源: CVE Program / CVE List V5
Vulnerability Description
Prometheus is an open-source monitoring system and time series database. In 2.23.0, Prometheus changed its default UI to the New ui. To ensure a seamless transition, the URL's prefixed by /new redirect to /. Due to a bug in the code, it is possible for an attacker to craft an URL that can redirect to any other URL, in the /new endpoint. If a user visits a prometheus server with a specially crafted address, they can be redirected to an arbitrary URL. The issue was patched in the 2.26.1 and 2.27.1 releases. In 2.28.0, the /new endpoint will be removed completely. The workaround is to disable access to /new via a reverse proxy in front of Prometheus.

| 1 | Prometheus 2.23.0 through 2.26.0 and 2.27.0 contains an open redirect vulnerability. To ensure a seamless transition to 2.27.0, the default UI was changed to the new UI with a URL prefixed by /new redirect to /. Due to a bug in the code, an attacker can redirect a user to a malicious site and possibly obtain sensitive information, modify data, and/or execute unauthorized operations. | https://github.com/projectdiscovery/nuclei-templates/blob/main/http/cves/2021/CVE-2021-29622.yaml | POC详情 |
