Problem

The export functionality fails to limit the result set to allowed columns of a particular database table. This allows authenticated users to export internal details of database tables to which they already have access.

Solution

Update to TYPO3 versions 7.6.57 ELTS, 8.7.47 ELTS, 9.5.35 ELTS, 10.4.29, 11.5.11 that fix the problem described above.

In order to address this issue, access to mentioned export functionality is completely denied for regular backend users.

ℹ️ Strong security defaults - Manual actions required
Following User TSconfig setting would allow using the export functionality for particular users:

options.impexp.enableExportForNonAdminUser = 1

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
