CVE-2020-36195Known exploitationNetwork attack vector

Application information disclosure via SQL injection

Published Apr 17, 2021 · Updated Sep 16, 2024

SQL injection in QNAP NAS running Multimedia Console or Media Streaming add-on allows remote attackers to obtain application information. QNAP has not published the affected request parameter, query-building code, or other details of the operation that incorporates untrusted input into SQL. Network access without authentication or user interaction is sufficient; the advisory directly reports only application-information disclosure.
