"The versions of Primavera Unifier installed on the remote host are affected by a denial of service (DoS) vulnerability
as referenced in the April 2024 CPU advisory. The vulnerability lies in the Primavera Unifier product of Oracle 
Construction and Engineering (component: Integration (Nimbus JOSE+JWT)). Supported versions that are affected are 
21.12.0-21.12.17, 22.12.0-22.12.12 and  23.12.0-23.12.3. Easily exploitable vulnerability allows an unauthenticated 
attacker with network access via HTTP to compromise Primavera Unifier. Successful attacks of this vulnerability can
result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Primavera Unifier.

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