- Severity: medium (CVSS 5.6 v3.1)
- Exploited in the wild: not listed in CISA KEV
- EPSS: 0.2% probability of exploitation in the next 30 days
- Public exploit or detection template: none known

Description
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.
Affected products
- Tenable ASUSTOR Data Master: from 4.1.0.rhu2 through 4.3.3.rof1; from 5.0.0.ra82 before 5.1.2.re51 — fixed in 5.1.2.re51
How to fix
Upgrade to a fixed version: Tenable ASUSTOR Data Master 5.1.2.re51. Check the vendor advisory for mitigations.
