CVE-2023-44206

Authenticated data disclosure and manipulation

Published Sep 27, 2023 · Updated Sep 23, 2024

Improper authorization in Acronis Cyber Protect 15 before build 35979 allows remote authenticated users to disclose or alter sensitive data. Acronis has not published the affected component, request field, or authorization operation that mishandles an attacker-controlled identifier. Exploitation requires low-privileged access from an adjacent network, and the public record does not bound which data can be read or changed.
