4DescriptionGitHub Advisory
OliveTin gives access to predefined shell commands from a web interface. Prior to version 3000.11.0, OliveTin allows an unauthenticated guest to terminate running actions through KillAction even when authRequireGuestsToLogin: true is enabled. Guests are correctly blocked from dashboard access, but can still call the KillAction RPC directly and successfully stop a running action. This is a broken access control issue that causes unauthorized denial of service against legitimate action executions. This issue has been patched in version 3000.11.0.
AnalysisAI
OliveTin versions prior to 3000.11.0 suffer from broken access control allowing unauthenticated users to invoke the KillAction RPC endpoint and terminate running shell command executions, bypassing authentication restrictions. Public exploit code exists for this vulnerability, enabling remote denial of service attacks against legitimate administrative actions. …
