OpenTelemetry Collector < 0.108.0 Authentication Bypass

medium Nessus Plugin ID 206657

Language:

Synopsis

An installed application on the remote host is affected by an authentication bypass vulnerability.

Description

The OpenTelemetry Collector running on the remote host is prior to 0.108.0. It is, therefore, affected by a timing discrepancy vulnerability, outlined below:

OpenTelemetry Collector module awsfirehosereceiver allows unauthenticated remote requests, even when configured to require a key.

OpenTelemetry Collector can be configured to receive CloudWatch metrics via an AWS Firehose Stream. Firehose sets the header X-Amz-Firehose-Access-Key with an arbitrary configured string. The OpenTelemetry Collector awsfirehosereceiver can optionally be configured to require this key on incoming requests. However, when this is configured it still accepts incoming requests with no key.

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

Solution

Upgrade to OpenTelemetry Collector 0.108.0 or later.
