{"schema":"threatline.record/2","record":{"id":"CVE-2026-100715","aliases":["GHSA-px4q-2rf7-cvcf"],"summary":"Froxlor before 2.3.12 Arbitrary File Deletion via Symlink","details":"Froxlor through 2.3.10 is vulnerable to arbitrary file deletion via symlink following in the FTP data deletion cron task. Cron task 8 (deleteFtpData), queued when an FTP account is deleted, calls FileDir::makeCorrectDir() without the $fixed_homedir argument, so the symlink component walk is skipped, and then executes 'rm -rf' as root on the resulting path with string-level guards only. Because makeCorrectDir() appends a trailing slash, GNU rm dereferences a symlink used either as an intermediate path component or as the final component. An authenticated customer who can write to the FTP home directory can plant a symlink between task insertion and cron execution, causing the root cron job to recursively delete arbitrary directory trees, resulting in cross-tenant data destruction and host denial of service. This issue is fixed in Froxlor 2.3.12.","categories":["Unclassified"],"product":"froxlor","vendor":"froxlor","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-100715","source_modified_at":"2026-09-28T16:59:54.596Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"froxlor","vendor":"froxlor","versions":[{"version":"0","status":"affected","versionType":"semver","lessThan":"2.3.12"},{"version":"2.3.12","status":"unaffected","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-100715","source_modified_at":"2026-09-28T16:59:54.596Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"froxlor","ecosystem":null},"version":"2.3.12","basis":"first unaffected version stated in the CVE record"}],"cvss":8.5,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00399,"percentile":0.32978,"score_date":"2026-10-23"},"published_at":"2026-09-26T13:24:07.174Z","modified_at":"2026-09-28T16:59:54.596Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-100715","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-28T16:59:54.596Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-100715","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/froxlor/froxlor/security/advisories/GHSA-px4q-2rf7-cvcf","tags":["exploit"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/froxlor-before-2.3.12-arbitrary-file-deletion-via-symlink","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"total","assessed_at":"2026-09-28T16:56:45.496100Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-28T16:59:54.596Z","content_hash":"5444687d44a790b8b52404062e9e212bd837af7fa5a312accae9b49d4ba20df7"}}
