"According to its self-reported version number, the instance of
Atlassian Bamboo running on the remote host is version 2.2.x prior to
5.8.5 or 5.9.x prior to 5.9.7. It is, therefore, affected by an
unspecified resource deserialization flaw due to improper validation
of user-supplied input. An unauthenticated, remote attacker can
exploit this to execute arbitrary Java code. Note that the attacker
must be able to access the Bamboo web interface.

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