{"schema":"threatline.record/2","record":{"id":"CVE-2026-100716","aliases":["GHSA-2wjc-6mgx-hq42"],"summary":"Froxlor before 2.3.12 Privilege Escalation via Symlink","details":"Froxlor is a server administration panel. In versions 2.3.10 and earlier, the customer data-export (DataDump) cron fails to validate intermediate path components of the export destination: Froxlor\\FileDir::makeCorrectDir() contains an off-by-one in its path-component walk that skips the first segment below the customer home directory, and the guard in ExportCron.php checks only the final component with is_link(). An authenticated customer whose account has the export feature enabled can schedule an export into a genuine subdirectory of their own webspace, then replace an intermediate path component with a symlink before the root-owned cron runs. The cron's `chown -R` then recursively changes ownership of the linked directory tree — for example /etc — to the customer's UID, yielding host root and cross-tenant compromise. Exploitation is deterministic and requires no race. This is an incomplete fix of GHSA-75h4-... The 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-2026-100716","source_modified_at":"2026-09-28T14:41:06.103Z","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-2026-100716","source_modified_at":"2026-09-28T14:41:06.103Z","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":9.4,"severity":"Critical","kev":{"listed":false},"epss":{"probability":0.00393,"percentile":0.32316,"score_date":"2026-10-23"},"published_at":"2026-09-26T13:24:07.854Z","modified_at":"2026-09-28T14:41:06.103Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-100716","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-28T14:41:06.103Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-100716","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-2wjc-6mgx-hq42","tags":["exploit"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/froxlor-before-2.3.12-privilege-escalation-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":"2026-09-28T14:40:34.238165Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-28T14:41:06.103Z","content_hash":"8eb2b4e55c11285f4f7021b6d4011b6bdb49fbe2b78111e1dda7233aead89ea7"}}
