CVE-2023-0113Network attack vector

Unauthenticated information disclosure via backup parameter

Published Jan 7, 2023 · Updated Aug 2, 2024

Information disclosure in the Backup Handler of Netis Netcore Router 2.2.0 through 2.2.6 allows remote attackers to read backup data. The handler exposes information when it processes a manipulated param.file.tgz value, but the CNA has not disclosed the underlying code-level error. Unauthenticated network access is sufficient; the published impact is limited to confidentiality, with no integrity or availability impact.
