CVE-2021-2106Network attack vector

Unauthenticated access and modification of interaction data

Published Jan 20, 2021 · Updated Sep 26, 2024

Compromise in Oracle Customer Interaction History 12.1.1 through 12.1.3 and 12.2.3 through 12.2.10 allows remote attackers to read and alter data. Oracle identifies the affected locus only as the Outcome-Result component and has not disclosed the faulty operation on untrusted HTTP input. Exploitation requires no credentials but does require a different person to interact, enabling access to critical or all readable interaction data and limited insertion, update, or deletion of data.
