{"id":"CVE-2026-44331","details":"In ProFTPD through 1.3.9a before 7666224, a SQL injection vulnerability in sqltab_fetch_clients_cb() in contrib/mod_wrap2_sql.c allows a remote attacker to inject arbitrary SQL commands via a crafted domain name that is accessed in a reverse DNS lookup. When \"UseReverseDNS on\" is enabled, the attacker-supplied hostname is passed unescaped into SQL queries. The character restrictions of DNS names may affect exploitability.","modified":"2026-08-15T09:53:22.551564Z","published":"2026-05-05T19:41:06.243Z","database_specific":{"cna_assigner":"mitre","cwe_ids":["CWE-89"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44331.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44331.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-44331"},{"type":"REPORT","url":"https://github.com/proftpd/proftpd/issues/2057"},{"type":"FIX","url":"https://github.com/proftpd/proftpd/commit/766622456440fbca33abd7927c523673a11d1ed1"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/proftpd/proftpd","events":[{"introduced":"0"},{"fixed":"f59f248e26bdfa514443e42bf72a145641df635d"},{"fixed":"766622456440fbca33abd7927c523673a11d1ed1"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.3.9a"}],"source":["DESCRIPTION","REFERENCES"]}}],"versions":["v1.3.9c","v1.3.9b","v1.3.9a","v1.3.10rc1","v1.3.9","v1.3.9rc3","v1.3.9rc2","v1.3.9rc1","v1.3.8","v1.3.8rc4","v1.3.8rc3","v1.3.8rc2","v1.3.8rc1","v1.3.7","v1.3.7rc4","v1.3.7rc3","v1.3.7rc2","v1.3.7rc1","v1.3.6","v1.3.6rc4","v1.3.6rc3","v1.3.6rc2","v1.3.6rc1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-44331.json","vanir_signatures_modified":"2026-08-15T09:53:22Z","vanir_signatures":[{"deprecated":false,"digest":{"line_hashes":["188482706554823101810217099371113475442","68337044015778869399813398219364202197","334365133394600081695344133386138485036","84965816477830368718499911502919309885","257689760143191922139795645690342910699","279078725103272610705499487142617442562","200755676198081997654057562277869569473","185160440974126000080114331374655820147","125458845817003328104264753665928310783","263248335264980344081424844571976700176","236080155514241972172298194553298885942","46161859100360679407753404889689615657","82567606603689545712045968230310458907","171101706885532581099216327660532567177","310242041935806729107316771436680950336"],"threshold":0.9},"id":"CVE-2026-44331-57249226","signature_type":"Line","signature_version":"v1","source":"https://github.com/proftpd/proftpd/commit/766622456440fbca33abd7927c523673a11d1ed1","target":{"file":"contrib/mod_wrap2_sql.c"}},{"target":{"file":"contrib/mod_wrap2_sql.c","function":"sqltab_fetch_clients_cb"},"deprecated":false,"digest":{"function_hash":"223779140751552999123681835048876320623","length":2108},"id":"CVE-2026-44331-f10affcc","signature_type":"Function","signature_version":"v1","source":"https://github.com/proftpd/proftpd/commit/766622456440fbca33abd7927c523673a11d1ed1"}]}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
