CVE-2018-5224

Bamboo did not correctly check if a configured Mercurial repository URI contained values that the Windows operating system may consider argument parameters. An 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 can execute code of their choice on systems that run a vulnerable version of Bamboo on the Windows operating system. All versions of Bamboo starting with 2.7.0 before 6.3.3 (the fixed version for 6.3.x) and from version 6.4.0 before 6.4.1 (the fixed version for 6.4.x) running on the Windows operating system are affected by this vulnerability.

8.8 3.0 HIGH
CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
