Vulnerability Title
Klever-Go: /log controls global node logging
来源: CVE Program / CVE List V5
Vulnerability Description
Klever-Go is the Go implementation of the Klever blockchain protocol. Prior to 1.7.20, the default-open GET /log WebSocket route configured in config/node/api.yaml and registered by network/api/api.go does not require authentication. The first client message is parsed as a logger Profile in network/api/logs/logSender.go and applied process-wide through Profile.Apply, allowing a remote client to change global log levels and formatting options until the connection closes. The same connection is registered as a log observer and can receive live process logs. An attacker can suppress normal logs, increase verbosity, distort operator visibility, and access operational information without credentials. This issue is fixed in version 1.7.20.
