Background
InfluxDB is a popular open-source time series database designed to handle high write and query loads. It provides a scalable and efficient solution for storing and analyzing time-stamped data. The affected package, github.com/influxdata/influxdb/services/httpd, is responsible for handling HTTP requests in InfluxDB. This vulnerability allows an attacker to bypass authentication by exploiting an issue in the authenticate function. Specifically, a JSON Web Token (JWT) token with an empty SharedSecret can be used to authenticate without a valid secret. This vulnerability has a critical severity rating and is assigned CVE-2019-20933.
Vulnerability Detail
The vulnerability in InfluxDB allows an attacker to bypass authentication and gain unauthorized access to the database. By providing a JWT token with an empty SharedSecret, the attacker can trick the authenticate function into granting access without a valid secret. This can lead to unauthorized data access, modification, or deletion. The vulnerability is critical, with a CVSS v3 score of 9.8, indicating a high level of severity. It affects InfluxDB versions prior to 1.7.6.

To disable authentication, modify the configuration file and set the auth-enabled option to false. Restart the InfluxDB service for the changes to take effect. It is strongly advised to apply the official fix by upgrading to a patched version.
Conclusion
InfluxDB before version 1.7.6 is vulnerable to an authentication bypass issue that allows unauthorized access to the database.
