CVE-2023-41742

Adjacent information disclosure via unrestricted IP binding

Published Aug 31, 2023 · Updated Sep 27, 2024

Information exposure in Acronis Agent before build 30430 and Cyber Protect 15 before build 35979 allows attackers on an adjacent network to read data. An affected service binds to an unrestricted IP address rather than a limited interface, exposing it to connections from unintended networks. Acronis has not identified the service, protocol, or exposed data, and the published impact is confidentiality only.
