Detailsinfo

A vulnerability classified as problematic was found in sysadminsmedia Homebox up to 0.25.x. This vulnerability affects the function HandleWipeInventory of the file backend/app/api/handlers/v1/v1_ctrl_actions.go of the component Wipe Inventory. The manipulation of the argument X-Tenant with an unknown input leads to a improper authorization vulnerability. The CWE definition for the vulnerability is CWE-285. The product does not perform or incorrectly performs an authorization check when an actor attempts to access a resource or perform an action. As an impact it is known to affect integrity, and availability. CVE summarizes:

HomeBox is a home inventory and organization system. Prior to 0.26.0, HandleWipeInventory in backend/app/api/handlers/v1/v1_ctrl_actions.go authorizes POST /v1/actions/wipe-inventory through the global ctx.User.IsOwner value instead of the caller's role in the active group, while the active group is selected through the X-Tenant request header. Because every self-registered user who creates a group receives the global owner value, a user who is also a member of another group can select that group with X-Tenant and permanently delete its complete inventory, which is not recoverable without external backups. This issue is fixed in version 0.26.0.
