OpenTelemetry Collector < 0.107.0 Timing Discrepancy

medium Nessus Plugin ID 205617

Language:

Synopsis

An installed application on the remote host is affected by a timing discrepancy vulnerability.

Description

The OpenTelemetry Collector running on the remote host is prior to 0.107.0. It is, therefore, affected by a timing discrepancy vulnerability, outlined below:

The bearertokenauth extension's server authenticator performs a simple, non-constant time string comparison of the received & configured bearer tokens. This impacts anyone using the `bearertokenauth` server authenticator. Malicious clients with network access to the collector may perform a timing attack against a collector with this authenticator to guess the configured token, by iteratively sending tokens and comparing the response time. This would allow an attacker to introduce fabricated or bad data into the collector's telemetry pipeline.

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 0.107.0 or later.
