{"id":"CVE-2026-54543","summary":"Froxlor DomainZones.add allows DNS zone-file RR injection via record/type fields","details":"Froxlor is open source server administration software. Prior to 2.3.8, the DomainZones.add API command in lib/Froxlor/Api/Commands/DomainZones.php accepts user-controlled record and type values without rejecting line delimiters, tab characters, semicolons, or unsupported DNS record types before lib/Froxlor/Dns/DnsEntry.php serializes the values into a BIND zone file. An authenticated customer with DNS-zone permissions can place a crafted value in the record field, or use the related type-field variant, to create additional resource-record lines that bypass Froxlor's field-level validation. BIND accepts the injected records, allowing modification of DNS data and possible DNS availability impact within a zone the caller is authorized to manage. This issue is fixed in version 2.3.8.","aliases":["GHSA-5rw4-4665-cvwf"],"modified":"2026-08-21T03:30:19.792191596Z","published":"2026-08-18T20:12:12.161Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-74"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54543.json"},"references":[{"type":"WEB","url":"https://github.com/froxlor/froxlor/releases/tag/2.3.8"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54543.json"},{"type":"ADVISORY","url":"https://github.com/froxlor/froxlor/security/advisories/GHSA-5rw4-4665-cvwf"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54543"},{"type":"FIX","url":"https://github.com/froxlor/froxlor/commit/a4f09f09fa71337b6cdff364d0a641d631a0130a"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/froxlor/froxlor","events":[{"introduced":"0"},{"fixed":"a4f09f09fa71337b6cdff364d0a641d631a0130a"},{"fixed":"e118217f90bb9c6a08f561d382d5ca2341eb4dfa"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"2.3.8"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["2.3.7","2.3.6","2.3.5","2.3.4","2.3.3","2.3.2","2.3.1","2.3.0","2.3.0-rc1","2.2.0-rc1","2.1.4","2.1.3","2.1.2","2.1.1","2.1.0","2.1.0-rc3","2.1.0-rc2","2.1.0-rc1","2.1.0-beta2","2.1.0-beta1","2.0.24","2.0.23","2.0.22","2.0.21","2.0.20","2.0.19","2.0.18","2.0.17","2.0.16","2.0.15","2.0.14","2.0.13","2.0.12","2.0.11","2.0.10","2.0.9","2.0.8","2.0.7","2.0.6","2.0.5","2.0.4","2.0.3","2.0.2","2.0.1","0.10.33","0.10.32","0.10.31","0.10.30","0.10.29.1","0.10.29","0.10.28","0.10.27","0.10.26","0.10.25","0.10.24","0.10.23.1","0.10.23","0.10.22","0.10.21","0.10.20","0.10.19","0.10.18","0.10.17","0.10.16","0.10.15","0.10.14","0.10.13","0.10.12","0.10.11","0.10.10","0.10.9","0.10.8","0.10.7","0.10.6","0.10.5","0.10.4","0.10.3","0.10.2","0.10.1","0.10.0","0.10.0-rc2","0.10.0-rc1","0.9.39.5","0.9.39.4","0.9.39.3","0.9.39.2","0.9.39.1","0.9.39","0.9.38.8","0.9.38.7","0.9.38.6","0.9.38.5","0.9.38.4","0.9.38.3","0.9.38.2","0.9.38.1","0.9.38","0.9.38-rc2","0.9.38-rc1","0.9.37","0.9.37-rc1","0.9.36","0.9.35.1","0.9.35","0.9.35-rc1","0.9.34.2","0.9.34.1","0.9.33-rc3","0.9.33-rc2","0.9.33-rc1","0.9.32","0.9.32-rc2","0.9.32-rc1","0.9.31-rc1","0.9.30","0.9.30-rc1","0.9.29","0.9.29-rc1","0.9.28.1","0.9.28","0.9.28-rc1","0.9.27","0.9.27-rc1","0.9.26","0.9.26-rc1","0.9.25","0.9.25-rc1","0.9.24","0.9.24-rc1","0.9.23","0.9.23-rc1","0.9.22","0.9.22-rc1","0.9.21","0.9.20.1","0.9.20","0.9.19","0.9.18.1","0.9.18"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-54543.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:L"}]}
