"According to its self-reported version, the installation of Atlassian Fisheye running on the remote Windows host is
prior to 4.4.6 or 4.5.x prior to 4.5.3. It is, therefore, affected by a remote command execution vulnerability due
to improper sanitization of characters in a Mercurial repository URI which may be interpreted as argument parameters
on the Windows operating system. An authenticated, remote attacker can exploit this to execute arbitrary commands 
with the privileges of the user running the server. 

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