CVE-2023-38844Public exploitNetwork attack vector

Database disclosure via unneutralized thesaurus parameter

Published Feb 21, 2024 · Updated Aug 29, 2024

SQL injection in PMB 7.4.7 and earlier allows remote attackers to read database data through the thesaurus parameter in export_skos.php. The endpoint passes the attacker-controlled thesaurus value into an SQL command without neutralizing SQL syntax. No authentication or user interaction is required; CISA's impact assessment limits the consequence to confidentiality.
