CVE-2023-26443Network attack vector

SQL injection via unencoded autocomplete quotes

Published Aug 2, 2023 · Updated Aug 2, 2024

SQL injection in OX App Suite backend 7.10.6-rev42 and 8.11 allows remote authenticated users to inject SQL via full-text autocomplete. The autocomplete path inserts user-supplied SQL syntax into a FULLTEXT query because single quotes are not encoded before statement construction. Administrative privileges and a crafted search are required; existing sanitization exposes SQL exceptions, while more damaging query execution is described as an unconfirmed escalation rather than a demonstrated consequence.
