Technical description

A vulnerability has been identified in Industrial Edge App Publisher (All versions < V1.27.9). The affected software does not properly validate the server certificate when initiating a TLS connection. This allows an attacker to intercept and relay communication (Man-in-the-Middle attack) and to spoof a trusted entity by interfering in the communication path between the client and the intended server.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
