CVE-2025-4517\n\ud83d\udd25 CVSS Score: 9.4 (cvssV3_1, Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:L)\n\ud83d\udd39 Description: Allows arbitrary filesystem writes outside the extraction directory during extraction with filter=\"data\".\n\n\nYou are affected by this vulnerability if using the tarfile\u00a0module to extract untrusted tar archives using TarFile.extractall()\u00a0or TarFile.extract()\u00a0using the filter=\u00a0parameter with a value of \"data\"\u00a0or \"tar\". See the tarfile  extraction filters documentation https://docs.python.org/3/library/tarfile.html#tarfile-extraction-filter \u00a0for more information.\n\nNote that for Python 3.14 or later the default value of filter=\u00a0changed from \"no filtering\" to `\"data\", so if you are relying on this new default behavior then your usage is also affected.\n\nNote that none of these vulnerabilities significantly affect the installation of source distributions which are tar archives as source distributions already allow arbitrary code execution during the build process. However when evaluating source distributions it's important to avoid installing source distributions with suspicious links.\n\ud83d\udccf Published: 2025-06-03T12:58:50.352Z\n\ud83d\udccf Modified: 2025-06-10T13:25:08.659Z\n\ud83d\udd17 References:\n1. https://github.com/python/cpython/issues/135034\n2. https://github.com/python/cpython/pull/135037\n3. https://mail.python.org/archives/list/security-announce@python.org/thread/MAXIJJCUUMCL7ATZNDVEGGHUMQMUUKLG/\n4. https://github.com/python/cpython/commit/3612d8f51741b11f36f8fb0494d79086bac9390a\n5. https://github.com/python/cpython/commit/9e0ac76d96cf80b49055f6d6b9a6763fb9215c2a\n6. https://gist.github.com/sethmlarson/52398e33eff261329a0180ac1d54f42f\n7. https://github.com/python/cpython/commit/19de092debb3d7e832e5672cc2f7b788d35951da\n8. https://github.com/python/cpython/commit/aa9eb5f757ceff461e6e996f12c89e5d9b583b01\n9. https://github.com/python/cpython/commit/28463dba112af719df1e8b0391c46787ad756dd9\n10. https://github.com/python/cpython/commit/4633f3f497b1ff70e4a35b6fe2c907cbe2d4cb2e\n11. https://github.com/python/cpython/commit/9c1110ef6652687d7c55f590f909720eddde965a\n12. https://github.com/python/cpython/commit/dd8f187d0746da151e0025c51680979ac5b4cfb1", "creation_timestamp": "2025-06-10T13:30:01.000000Z"}, {"uuid": "0cffa97b-7f23-4be6-8324-25cee77f524d", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2025-4517", "type": "seen", "source": "https://t.me/bagl3y_notes/280", "content": "\ud83d\udfe2 \u041d\u043e\u0432\u044b\u0439 \u0432\u0438\u0434\u0435\u043e-\u0440\u0430\u0437\u0431\u043e\u0440 \ud83d\udc9a \u0442\u0430\u0447\u043a\u0438 \u043e\u0442 ippsec'a\n\n\n\u2049\ufe0f   \u0410\u043d\u043e\u043d\u0438\u043c\u043d\u044b\u0439 \u043b\u043e\u0433\u0438\u043d (\u044e\u0437\u0435\u0440 anonymous \u0441 \u043f\u0443\u0441\u0442\u044b\u043c \u043f\u0430\u0440\u043e\u043b\u0435\u043c) \u043d\u0430 Wing FTP Server v7.4.3 \u27a1\ufe0f\u0438\u0449\u0435\u043c \"Wingftp v7.4.3 exploit\", \u043d\u0430\u0445\u043e\u0434\u0438\u043c CVE-2025-47812 (null-byte injection \u0432 \u0432\u0435\u0431-\u0438\u043d\u0442\u0435\u0440\u0444\u0435\u0439\u0441\u0435 \u0434\u043b\u044f \u0432\u043d\u0435\u0434\u0440\u0435\u043d\u0438\u044f Lua-\u043a\u043e\u0434\u0430 \u0432 \u0441\u0435\u0441\u0441\u0438\u043e\u043d\u043d\u044b\u0439 \u0444\u0430\u0439\u043b) \u27a1\ufe0f  \u0432 /opt/wftpserver/Data \u043d\u0430\u0445\u043e\u0434\u0438\u043c XML-\u0444\u0430\u0439\u043b\u044b \u0430\u043a\u043a\u0430\u0443\u043d\u0442\u043e\u0432 \u0441 salted SHA256-\u0445\u0435\u0448\u0430\u043c\u0438 (SHA256(pass + \"WingFTP\")), \u0431\u0440\u0443\u0442\u0438\u043c \u0447\u0435\u0440\u0435\u0437 hashcat mode 1410 -
