CVE-2020-24402

Magento version 2.4.0 and 2.3.5p1 (and earlier) are affected by an incorrect permissions vulnerability in the Integrations component. This vulnerability could be abused by authenticated users with permissions to the Resource Access API to delete customer details via the REST API without authorization.

Weakness

During installation, installed file permissions are set to allow anyone to modify those files.

Affected Software

Potential Mitigations

• Compartmentalize the system to have “safe” areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
• Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
