vulnerability.");

"According to its self-reported version number, the instance of
Atlassian Bamboo running on the remote host is 5.x prior to 5.15.7 or
6.0.x prior to 6.0.1. It is, therefore, affected by a remote code
execution vulnerability due to improper validation of edit permissions
for deployment projects. An authenticated, remote attacker can exploit
this to create a deployment project and use it to execute arbitrary
code.

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