**Name of the Vulnerable Software and Affected Versions**
Oracle WebCenter Sites version 12.2.1.3.0
**Description**
The issue is related to insufficient access control in the Advanced UI interface of the Oracle WebCenter Sites application, allowing a remote attacker to gain unauthorized access to protected information via the HTTP protocol. Successful attacks may require human interaction and can significantly impact additional products, resulting in unauthorized access to some data, including update, insert, or delete access, as well as unauthorized read access to a subset of the data.
**Recommendations**
For version 12.2.1.3.0, consider restricting access to the Advanced UI interface until a patch is available.
As a temporary workaround, limit the use of the HTTP protocol to minimize the risk of exploitation.
Restrict access to sensitive data to prevent unauthorized updates, inserts, or deletes.
