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).

An update of the kapacitor package has been released.

The remote Ubuntu 18.04 LTS / 20.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-5451-1 advisory.

    Ilya Averyanov discovered that an InfluxDB vulnerability allowed attackers to bypass authentication and     gain access to any known database user.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

An update of the influxdb package has been released.

It was discovered that incorrect validation of JWT tokens in InfluxDB, a time series, metrics, and analytics database, could result in authentication bypass.

An issue has been found in influxdb, a scalable datastore for metrics, events, and real-time analytics. By using a JWT token with an empty shared secret, one is able to bypass authentication in services/httpd/handler.go.

For Debian 9 stretch, this problem has been fixed in version 1.1.1+dfsg1-4+deb9u1.

We recommend that you upgrade your influxdb packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
