{"schema":"threatline.record/2","record":{"id":"CVE-2026-100714","aliases":["GHSA-3w4g-cmpj-rj42"],"summary":"Froxlor before 2.3.12 Command Injection via letsencryptchallengepath","details":"Froxlor before 2.3.12 does not restrict or escape the system.letsencryptchallengepath setting: unlike sibling settings hardened in GHSA-33mp, the field has no string_regexp or required_otp guard, and its value is concatenated unescaped into the acme.sh command line built in lib/Froxlor/Cron/Http/LetsEncrypt/AcmeSh.php and executed by the root cron via FileDir::safe_exec. Because safe_exec only blacklists shell metacharacters such as ; | & > < \\ $ ~ ?, spaces and quotes survive and the value is word-split into additional acme.sh arguments. An administrator, or any actor able to write settings (for example through the settings-import API), can therefore inject acme.sh options such as --renew-hook, --pre-hook or --post-hook to obtain arbitrary command execution as root at the next Let's Encrypt cron run, or use --config-home/--cert-home for arbitrary file writes. Versions up to and including 2.3.10 are affected; the issue is fixed in 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-2026-100714","source_modified_at":"2026-09-26T23:07:30.927Z","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-2026-100714","source_modified_at":"2026-09-26T23:07:30.927Z","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":0.00549,"percentile":0.45174,"score_date":"2026-10-23"},"published_at":"2026-09-26T13:24:06.446Z","modified_at":"2026-09-26T23:07:30.927Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-100714","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-26T23:07:30.927Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-100714","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-3w4g-cmpj-rj42","tags":["vendor-advisory"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/froxlor-before-2.3.12-command-injection-via-letsencryptchallengepath","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"total","assessed_at":"2026-09-26T23:07:23.597548Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-26T23:07:30.927Z","content_hash":"80666c4dc98ca3c94563cc0dc22849230ec82c9fc83769f0dfe6e1499c6fba87"}}
