Description#
NexoPOS through 6.3.0 contains a missing authorization vulnerability that allows authenticated cashiers to manipulate other cashiers' register sessions because CashRegistersService never compares used_by with the user. Attackers holding the default nexopos.use.registers permission can submit closing, cash-in, or cash-out actions to POST /api/cash-registers/{action}/{register} to force-close sessions or alter balances.
Impact#
Per CVSS v3.1: confidentiality impact none, integrity impact low, availability impact low. Attack vector: network.
Weaknesses#
- CWE-639 Authorization Bypass Through User-Controlled Key
