Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-287: Improper Authentication, where when an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. In Github.com/influxdata/influxdb, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

InfluxDB before 1.7.6 has an authentication bypass vulnerability in the authenticate function in `services/httpd/handler.go` because a JWT token may have an empty SharedSecret (aka shared secret).
