{"id":"CVE-2024-29188","aliases":["GHSA-jx4p-m4wm-vvjg"],"url":"https://o3.security/vulnerability/CVE-2024-29188","summary":"Malicious directory junction can cause WiX RemoveFoldersEx to possibly delete elevated files","details":"WiX toolset lets developers create installers for Windows Installer, the Windows installation engine. The custom action behind WiX's `RemoveFolderEx` functionality could allow a standard user to delete protected directories. `RemoveFolderEx` deletes an entire directory tree during installation or uninstallation. It does so by recursing every subdirectory starting at a specified directory and adding each subdirectory to the list of directories Windows Installer should delete. If the setup author instructed `RemoveFolderEx` to delete a per-user folder from a per-machine installer, an attacker could create a directory junction in that per-user folder pointing to a per-machine, protected directory. Windows Installer, when executing the per-machine installer after approval by an administrator, would delete the target of the directory junction. This vulnerability is fixed in 3.14.1 and 4.0.5.","published":"2024-03-24T19:46:25.875Z","modified":"2026-08-12T15:12:58.318114Z","cvss":{"score":7.9,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:C/C:N/I:H/A:H"},"epss":{"score":0.00242,"percentile":0.15169,"asOf":"2026-08-30"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"NuGet","name":"wix","fixedVersion":"3.14.1"},{"ecosystem":"NuGet","name":"wix","fixedVersion":"4.0.5"},{"ecosystem":"NuGet","name":"WixToolset.Util.wixext","fixedVersion":"4.0.5"}],"fix":{"url":"https://github.com/wixtoolset/wix/commit/2e5960b575881567a8807e6b8b9c513138b19742","label":"wixtoolset/wix@2e5960b"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/29xxx/CVE-2024-29188.json"},{"type":"ADVISORY","url":"https://github.com/wixtoolset/issues/security/advisories/GHSA-jx4p-m4wm-vvjg"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-29188"},{"type":"FIX","url":"https://github.com/wixtoolset/wix/commit/2e5960b575881567a8807e6b8b9c513138b19742"},{"type":"FIX","url":"https://github.com/wixtoolset/wix3/commit/93eeb5f6835776694021f66d4226c262c67d487a"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T15:12:58.318114Z"}}
