Summary

Traefik is an open source HTTP reverse proxy and load balancer. Versions prior to 2.9.6 are subject to a potential vulnerability in Traefik displaying the Authorization header in its debug logs. In certain cases, if the log level is set to DEBUG, credentials provided using the Authorization header are displayed in the debug logs. Attackers must have access to a users logging system in order for credentials to be stolen. This issue has been addressed in version 2.9.6. Users are advised to upgrade. Users unable to upgrade may set the log level to `INFO`, `WARN`, or `ERROR`.

Common Weakness Enumeration (CWE)

CWE-532 - Information Exposure Through Log Files

Common Attack Pattern Enumeration and Classification (CAPEC)

Fuzzing and observing application log data/errors for application mapping
An attacker sends random, malformed, or otherwise unexpected messages to a target application and observes the application's log or error messages returned. Fuzzing techniques involve sending random or malformed messages to a target and monitoring the target's response. The attacker does not initially know how a target will respond to individual messages but by attempting a large number of message variants they may find a variant that trigger's desired behavior. In this attack, the purpose of the fuzzing is to observe the application's log and error messages, although fuzzing a target can also sometimes cause the target to enter an unstable state, causing a crash. By observing logs and error messages, the attacker can learn details about the configuration of the target application and might be able to cause the target to disclose sensitive information.
