A privilege escalation vulnerability is introduced since any location in the system-wide PATH environment variable may be used to load code that runs with privileges.\r\n\r\n### Impact\r\nBy placing a specially-crafted DLL file in the `C:\\ProgramData\\Boxstarter` directory, an unprivileged user may be able to execute arbitrary code with SYSTEM privileges on a Windows system with the vulnerable Boxstarter software installed. See [DLL Search Order Hijacking](https://attack.mitre.org/techniques/T1574/001/) for more details.\r\n\r\n### Solution\r\n####Apply an update\r\n\r\nThis vulnerability is addressed in Chocolatey Boxstarter version 2.13.0. Please see the [security advisory](https://github.com/chocolatey/boxstarter/security/advisories/GHSA-rpgx-h675-r3jf) for more details.\r\n\r\n### Acknowledgements\r\nThis vulnerability was reported by Will Dormann of the CERT/CC.\r\n\r\nThis document was written by Will Dormann.","title":"Summary"},{"category":"legal_disclaimer","text":"THIS DOCUMENT IS PROVIDED ON AN 'AS IS' BASIS AND DOES NOT IMPLY ANY KIND OF GUARANTEE OR WARRANTY, INCLUDING THE WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR USE.
