CVE-2021-2186Network attack vector

Unauthenticated data disclosure and modification

Published Apr 22, 2021 · Updated Sep 26, 2024

Oracle iStore 12.1.1 through 12.1.3 and 12.2.3 through 12.2.10 allows remote attackers to read and modify data via HTTP. Oracle identifies the Shopping Cart component but does not disclose the flawed request, handler, or input operation that causes the compromise. No credentials are required, but exploitation requires interaction by another person; impact is bounded to complete access to iStore-readable data and limited updates, inserts, or deletions.
