6.1.0 before 6.1.2 (the fixed version for 6.1.x) allow remote attackers who have admin permissions to achieve remote
code execution on a Bitbucket server instance via path traversal through the Data Center migration tool.

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