According to its self-reported version, the installation of Atlassian Crucible 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.
