newbee-mall stores and verifies user passwords using an unsalted MD5 hashing algorithm. The implementation does not incorporate per-user salts or computational cost controls, enabling attackers who obtain password hashes through database exposure, backup leakage, or other compromise vectors to rapidly recover plaintext credentials via offline attacks.

newbee-mall includes pre-seeded administrator accounts in its database initialization script. These accounts are provisioned with a predictable default password. Deployments that initialize or reset the database using the provided schema and fail to change the default administrative credentials may allow unauthenticated attackers to log in as an administrator and gain full administrative control of the application.

A vulnerability was determined in newbee-mall-plus 2.0.0. This impacts the function Upload of the file src/main/java/ltd/newbee/mall/controller/common/UploadController.java of the component Product Information Edit Page. This manipulation of the argument File causes unrestricted upload. The attack may be initiated remotely. The exploit has been publicly disclosed and may be utilized. The vendor was contacted early about this disclosure but did not respond in any way.
