"The Sonatype Nexus Repository Manager server application running on the remote host is version 3.x prior
 to 3.21.2. It is, therefore, affected by a remote code execution vulnerability, which allows for an 
 attacker with any type of account on NXRM to execute arbitrary code by crafting a malicious request to NXRM.
 
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
