EUVDB-ID: #VU12762

Risk: Low

CVSSv4.0: 6.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2018-5224

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

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.

Mitigation

Update to version 6.3.3 or 6.4.1.
