DescriptionCVE.org

A third-party NAT traversal module fails to validate SSL/TLS certificates when connecting to the signaling server. While subsequent access to device services requires additional authentication, a Man-in-the-Middle (MitM) attacker can intercept or redirect the NAT tunnel establishment. This could allow an attacker to disrupt service availability or facilitate further targeted attacks by acting as a proxy between the user and the device services. Affected products and versions include: from ADM 4.1.0 through ADM 4.3.3.ROF1 as well as from ADM 5.0.0 through ADM 5.1.1.RCI1.

AnalysisAI

Data Master ADM 4.1.0-4.3.3 and 5.0.0-5.1.1 are vulnerable to man-in-the-middle attacks due to improper SSL/TLS certificate validation in the NAT traversal module, allowing attackers to intercept tunnel establishment and redirect connections to the signaling server. An attacker exploiting this can proxy device service communications, disrupt availability, or position themselves for follow-on attacks, though further authentication is required to access actual device services. No patch is currently available.
