"The version of IBM App Connect Enterprise installed on the remote host is 12.0.1.x prior to 12.0.12.30, or 13.0.1.x
prior or equal to 13.0.8.2. It is, therefore, affected by an arbitrary file write vulnerability. IBM App Connect Enterprise
could allow a local attacker to perform an arbitrary file write due to improper validation of pathnames during archive
extraction.

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