6.5Medium

Attack vector: Network
Complexity: Low
Privileges needed: Low
User interaction: None
Impact: High impact on confidentiality
Weakness: CWE-639

Impact

Authenticated attackers can view metadata and download unauthorized file attachments across tenants. To exploit it, an attacker needs valid credentials and network access to the API.

Root cause

The listFileByBizId endpoint fails to enforce tenant or object-level authorization checks on the user-supplied bizId parameter.

Affected systems

lamp-cloud through 5.10.1

CVSS v3.1 · CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N

Fix & remediation

No fixed version is specified in the advisory; check upstream for patches past 5.10.1. As an interim mitigation, restrict access to the listFileByBizId API endpoint and block unauthenticated requests to /anyTenant/file at the reverse proxy or API gateway.

AI-suggested. Run it in staging first and check it against the vendor advisory. Why?

NVD description

lamp-cloud through 5.10.1 contains an insecure direct object reference vulnerability that allows authenticated users to list other business objects' file attachments by supplying an arbitrary bizId to the listFileByBizId endpoint. Attackers can retrieve file names, storage paths, MD5 hashes and stored URLs, which in default LOCAL storage are served without login under /anyTenant/file.
