Customer Advisory
Potential Security Vulnerability Has Been Discovered in Wonderware InBatch Server and
Foxboro I/A Series Batch Server
17, 2010

Schneider Electric is committed to ensuring that our customers and employees are kept current on issues that might affect or improve product, system or process operation. We are dedicated to providing product and application reliability, and exceptional client service.

Customer Advisories are intended to inform you of the possibility of a situation occurring at system installations, and the identified resolution. Invensys recommends that our customers consider taking action to help prevent occurrence of the identified situation during your production process.

A vulnerability has been discovered in InBatch Server and I/A Batch Server in all supported versions of Wonderware InBatch and I/A Series Batch. This vulnerability, if exploited, could allow Denial of Service, the consequence of which is a crash of the InBatch Server.


The Invensys cyber-security team is collaborating with the United States government (ICS-CERT) to ensure an appropriate and timely official public communication of the issue.

·         Invensys Operations Management has prepared Invensys Operations Management Security Bulletin LFSEC00000051


The InBatch Server component contains a vulnerability that may allow Denial of Service in an unsecure deployment. The rating is medium and would require a malicious application that has access to port 9001 on the batch server and understands the protocol used on that port to send a partially valid message that overflows an internal buffer.

Any machine on which InBatch Server or I/A Series Batch server is installed is affected. No other components of Wonderware InBatch and I/A Series Batch are affected. Further mitigation beyond that identified in this Alert will be made available to customers running Wonderware InBatch and I/A Series Batch.


Additional mitigation, such as software updates to address the issue for all supported versions of affected products, is being prepared and will be communicated at a later date.

Until product updates are available, customers using versions of Wonderware InBatch and I/A Series Batch SHOULD make sure that their Batch Server is on a secured network inaccessible from the Internet.
