Authenticated database disclosure via unsafe baseKey substitution
Published Mar 30, 2022 · Updated Aug 4, 2024
SQL injection in Oasys oa_system 2021-09-07 allows remote authenticated users to read database data through a crafted baseKey value. The sortMyNotice query in src/main/resources/mappers/notice-mapper.xml expands baseKey with MyBatis ${...} substitution inside a LIKE pattern instead of binding it as a parameter. A regular application account and access to /informlistpaging are required; successful injection exposes database information without reported modification or service interruption.
