Sensitive information disclosure via out-of-bounds read
Published Jun 11, 2021 · Updated Sep 17, 2024
An out-of-bounds read in QNAP Systems QSS before 1.0.2 build 20210122 allows remote attackers to read sensitive system information. QNAP identifies an out-of-bounds memory read but has not published the affected component, the input that crosses its boundary, or the request path that reaches it. Exploitation is reachable from an adjacent network without authentication or user interaction; the disclosed consequence is limited to reading sensitive information.
