**Description**
The issue exists due to insufficient input validation in the Core component of Oracle Coherence, allowing a remote attacker to cause the device to hang or deny service. Successful attacks can result in unauthorized ability to cause a hang or frequently repeatable crash of Oracle Coherence. The vulnerability can be exploited via T3, IIOP by an unauthenticated attacker with network access.
**Recommendations**
For versions 3.7.1.0, 12.1.3.0.0, 12.2.1.3.0, 12.2.1.4.0, and 14.1.1.0.0, consider restricting network access via T3, IIOP to minimize the risk of exploitation until a patch is available.
As a temporary workaround, consider implementing additional validation for incoming requests to prevent unauthorized access.
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
