Package

gomod github.com/traefik/traefik (Go)

Affected versions

>= 1.7.0, <= 1.7.11

Description

types/types.go in Containous Traefik 1.7.x through 1.7.11, when the --api flag is used and the API is publicly reachable and exposed without sufficient access control (which is contrary to the API documentation), allows remote authenticated users to discover password hashes by reading the Basic HTTP Authentication or Digest HTTP Authentication section, or discover a key by reading the ClientTLS section.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
