{"id":"CVE-2026-41230","aliases":["GHSA-47hf-23pw-3m8c"],"url":"https://o3.security/vulnerability/CVE-2026-41230","summary":"Froxlor has a BIND Zone File Injection via Unsanitized DNS Record Content in DomainZones::add()","details":"Froxlor is open source server administration software. Prior to version 2.3.6, `DomainZones::add()` accepts arbitrary DNS record types without a whitelist and does not sanitize newline characters in the `content` field. When a DNS type not covered by the if/elseif validation chain is submitted (e.g., `NAPTR`, `PTR`, `HINFO`), content validation is entirely bypassed. Embedded newline characters in the content survive `trim()` processing, are stored in the database, and are written directly into BIND zone files via `DnsEntry::__toString()`. An authenticated customer can inject arbitrary DNS records and BIND directives (`$INCLUDE`, `$ORIGIN`, `$GENERATE`) into their domain's zone file. Version 2.3.6 fixes the issue.","published":"2026-04-23T03:47:11.258Z","modified":"2026-08-12T03:51:13.573605222Z","cvss":{"score":8.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:H/A:L"},"epss":{"score":0.00347,"percentile":0.27534,"asOf":"2026-08-12"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"froxlor/froxlor","fixedVersion":"2.3.6"}],"fix":{"url":"https://github.com/froxlor/froxlor/commit/47a8af5d9523cb6ec94567405cfc2e294d3a1442","label":"froxlor/froxlor@47a8af5"},"references":[{"type":"WEB","url":"https://github.com/froxlor/froxlor/releases/tag/2.3.6"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/41xxx/CVE-2026-41230.json"},{"type":"ADVISORY","url":"https://github.com/froxlor/froxlor/security/advisories/GHSA-47hf-23pw-3m8c"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-41230"},{"type":"FIX","url":"https://github.com/froxlor/froxlor/commit/47a8af5d9523cb6ec94567405cfc2e294d3a1442"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:13.573605222Z"}}
