QID 981231

QID 981231: Go (go) Security Update for github.com/cortexproject/cortex (GHSA-jphm-g89m-v42p)

An issue was discovered in Grafana Cortex through 1.9.0. The header value X-Scope-OrgID is used to construct file paths for rules files, and if crafted to conduct directory traversal such as ae ../../sensitive/path/in/deployment pathname, then Cortex will attempt to parse a rules file at that location and include some of the contents in the error message. (Other Cortex API requests can also be sent a malicious OrgID header, e.g., tricking the ingester into writing metrics to a different location, but the effect is nuisance rather than information disclosure.)

Successful exploitation of this vulnerability may affect the confidentiality, integrity, and availability of the targeted user.

CVSS V3 rated as Medium - 5.3 severity.

CVSS V2 rated as Medium - 5 severity.
