Vulnerability details
The vulnerability allows a remote authenticated attacker to execute arbitrary code on the target system.
The weakness exists due to incorrect check if a configured Mercurial repository URI contained values that the Windows operating system may consider argument parameters. A remote attacker, who has permission to create a repository in Bamboo, edit an existing plan in Bamboo that has a non-linked Mercurial repository or create a plan in Bamboo either globally or in a project using Bamboo Specs, can execute arbitrary code.
Successful exploitation of the vulnerability may result in system compromise.
