CVE-2023-24471Network attack vector

Restricted-data disclosure via unenforced debug authorization

Published Aug 9, 2023 · Updated Aug 2, 2024

Incorrect authorization in Nozomi Networks Guardian and CMC before 22.6.2 allows remote authenticated users to read restricted data. The assertion debug function fails to enforce the visibility restrictions applied to the underlying assertions. A reduced-visibility account can retrieve information otherwise blocked in the Query and Assertions functions.
