Deeper analysis

DIAView versions 4.2.0 and earlier contain a directory traversal vulnerability tracked as CVE-2025-53417 and assigned CWE-35. The flaw resides in the industrial visualization software and permits unauthorized access to files outside intended directories, resulting in information disclosure. It carries a CVSS 4.0 score of 9.3 with a network attack vector, low complexity, and no required privileges or user interaction.

An unauthenticated remote attacker can exploit the issue over the network to read sensitive files on the affected system. Successful traversal can expose configuration data, credentials, or other restricted content, enabling further compromise of the host and any connected industrial control environments.
