"The version of Oracle Access Manager installed on the remote host is missing a security patch from the July 2023 CPU 
Advisory. It is, therefore, affected by denial of service vulnerability. Oracle Access Manager product of Oracle Fusion 
Middleware (component: Centralized Thirdparty Jars (jackson-databind)). The supported version that is affected is 
12.2.1.4.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise 
Oracle Access Manager. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or 
frequently repeatable crash (complete DOS) of Oracle Access Manager. 

Note that Nessus has not attempted to exploit these issues but has instead
relied only on the application's self-reported version number.");
