CVE-2024-20938Network attack vector

Unauthorized data changes via undisclosed ECC operation

Published Jan 16, 2024 · Updated Jun 3, 2025

Improper access control in Oracle iStore 12.2.3 through 12.2.13 allows remote attackers to read and modify data via HTTP. Oracle has not disclosed the faulty ECC endpoint or operation that mishandles untrusted input. Exploitation is unauthenticated but requires another person to interact, and successful attacks can read a subset of accessible data and update, insert, or delete some accessible data.
