      Bamboo did not check that the name of a branch in a Mercurial repository contained argument parameters. An attacker who has permission to do one or more of the following:

      • create a repository in Bamboo
      • edit an existing plan in Bamboo that has a non-linked Mercurial repository
      • create or edit a plan in Bamboo when there is at least one linked Mercurial repository that the attacker has permission to use
      • commit to a Mercurial repository used by a Bamboo plan which has branch detection enabled
        can execute code of their choice on systems that run a vulnerable version of Bamboo Server.

      Affected versions:

      • Versions of Bamboo starting with 2.7.0 before 6.1.6 (the fixed version for 6.1.x) and from 6.2.0 before 6.2.5 (the fixed version for 6.2.x) are affected by this vulnerability.
