CVE-2024-42368 Â (opens in a new tab)How to fix?
Upgrade github.com/open-telemetry/opentelemetry-collector-contrib/extension/bearertokenauthextension to version 0.107.0 or higher.
Overview
Affected versions of this package are vulnerable to Timing Attack due to the bearertokenauth server authenticator. An attacker can guess the configured token by iteratively sending tokens and comparing the response time, potentially introducing fabricated or bad data into the collector's telemetry pipeline.
Workaround
Users unable to upgrade to the fixed version can not expose the receiver using bearertokenauth to network segments accessible by potential attackers by changing the receiver to use a different authentication extension instead or disabling the receiver relying on bearertokenauth.
