🛡️ Security Considerations
While WebAccess/SCADA offers robust features, it's essential to be aware of potential security vulnerabilities. For instance, versions prior to 9.1.4 were found to have an untrusted pointer dereference vulnerability (CVE-2023-1437), which could allow remote file system access and command execution. It's crucial to ensure that your system is updated to the latest version to mitigate such risks.
