CVE-2023-39420Network attack vector

Administrative access via predictable daily password

Published Sep 7, 2023 · Updated Sep 26, 2024

Hard-coded credentials in IRM Next Generation 5.3.2.15 allow remote attackers to gain unrestricted administrative application access. RDPCore.dll derives the admin account password with a routine that produces a predictable value for each day. An attacker must reverse-engineer that routine and reach a customer management interface or API, after which the shared account permits unrestricted application access.
