{"id":"CVE-2023-4052","details":"The Firefox updater created a directory writable by non-privileged users. When uninstalling Firefox, any files in that directory would be recursively deleted with the permissions of the uninstalling user account. This could be combined with creation of a junction (a form of symbolic link) to allow arbitrary file deletion controlled by the non-privileged user. \n*This bug only affects Firefox on Windows. Other operating systems are unaffected.* This vulnerability affects Firefox \u003c 116, Firefox ESR \u003c 115.1, and Thunderbird \u003c 115.1.","modified":"2026-03-15T22:47:17.723334Z","published":"2023-08-01T15:15:10.207Z","related":["SUSE-SU-2023:3161-1","SUSE-SU-2023:3162-1","SUSE-SU-2023:3163-1","SUSE-SU-2023:3228-1","openSUSE-SU-2024:13124-1","openSUSE-SU-2024:13202-1","openSUSE-SU-2024:14572-1"],"references":[{"type":"ADVISORY","url":"https://www.mozilla.org/security/advisories/mfsa2023-31/"},{"type":"ADVISORY","url":"https://www.mozilla.org/security/advisories/mfsa2023-33/"},{"type":"ADVISORY","url":"https://www.mozilla.org/security/advisories/mfsa2023-29/"},{"type":"REPORT","url":"https://bugzilla.mozilla.org/show_bug.cgi?id=1824420"}],"affected":[{"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-4052.json","unresolved_ranges":[{"events":[{"introduced":"0"},{"fixed":"116.0"}]},{"events":[{"introduced":"0"},{"fixed":"115.1"}]}]}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N"}]}
