A PyInstaller built application, elevated as a privileged process, may be tricked by an unprivileged attacker into deleting files the unprivileged user does not otherwise have access to. A user is affected if **all** the following are satisfied: 1. The user runs an application containing either `matplotlib` or `win32com`. 2. The application is ran as administrator (or at least a user with higher privileges than the attacker). 3. The user's temporary directory is not locked to that specific user (most likely due to `TMP`/`TEMP` environment variables pointing to an unprotected, arbitrary, non default location). Either: A. The attacker is able to very carefully time the replacement of a temporary file with a symlink. This switch must occur exactly between `shutil.rmtree()`'s builtin symlink check and the deletion itself B: The application was built with Python 3.7.x or earlier which has no protection against Directory Junctions links. The vulnerability has been addressed in PR #7827 which corresponds to `pyinstaller >= 5.13.1`. Users are advised to upgrade. There are no known workarounds for this vulnerability.","references":[{"reference_url":"https://github.com/pyinstaller/pyinstaller/pull/7827","reference_id":"","reference_type":"","scores":[{"value":"7.8","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}],"url":"https://github.com/pyinstaller/pyinstaller/pull/7827"},{"reference_url":"https://github.com/pyinstaller/pyinstaller/security/advisories/GHSA-9w2p-rh8c-v9g5","reference_id":"","reference_type":"","scores":[{"value":"7.8","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}],"url":"https://github.com/pyinstaller/pyinstaller/security/advisories/GHSA-9w2p-rh8c-v9g5"},{"reference_url":"https://github.com/python/cpython/blob/0fb18b02c8ad56299d6a2910be0bab8ad601ef24/Lib/shutil.py#L623","reference_id":"","reference_type":"","scores":[{"value":"7.8","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}],"url":"https://github.com/python/cpython/blob/0fb18b02c8ad56299d6a2910be0bab8ad601ef24/Lib/shutil.py#L623"},{"reference_url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/2K2XIQLEMZIKUQUOWNDYWTEWYQTKMAN7/","reference_id":"","reference_type":"","scores":[{"value":"7.8","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}],"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/2K2XIQLEMZIKUQUOWNDYWTEWYQTKMAN7/"},{"reference_url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/ISRWT34FAF23PUOLVZ7RVWBZMWPDR5U7/","reference_id":"","reference_type":"","scores":[{"value":"7.8","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}],"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/ISRWT34FAF23PUOLVZ7RVWBZMWPDR5U7/"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/81218?format=json","purl":"pkg:pypi/pyinstaller@5.13.1","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/pyinstaller@5.13.1"}],"aliases":["CVE-2023-49797","GHSA-9w2p-rh8c-v9g5","PYSEC-2023-292"],"risk_score":null,"exploitability":null,"weighted_severity":null,"resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-ksr4-5d9x-tfec"}],"fixing_vulnerabilities":[],"risk_score":null,"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/pyinstaller@4.1"}
