Upgrade Steeltoe.Management.Endpoint to version 4.3.0 or higher.
Overview
Steeltoe.Management.Endpoint is a package that provides building blocks for development of .NET applications that integrate with Spring and Spring Boot environments, as well as Cloud Foundry and Kubernetes with first-party support for Tanzu.
Affected versions of this package are vulnerable to Information Exposure via the MaskedUri handling in HttpExchangeRequest and HttpExchangesRepository. An attacker can expose secrets in /actuator/httpexchanges responses and DEBUG logs by sending requests with sensitive values in query-string parameters. The affected code masks embedded user:password@host credentials but leaves query strings intact, so tokens, API keys, and similar data are recorded and returned verbatim in the uri field for any caller that can access the endpoint.
Workarounds
- Remove
httpexchangesfromManagement:Endpoints:Web:Exposure:Include, or restrict the endpoint behind authentication, so unauthenticated callers cannot retrieve prior request URIs containing secrets. - Set
Management:Endpoints:HttpExchanges:IncludeQueryStringtofalse, so query strings are stripped from recorded exchanges and secrets in query parameters are not returned in/actuator/httpexchangesor written to DEBUG logs.
