Organizations that use the IntraVUE network visualization software from Network Vision are advised to update their installations as soon as possible because older versions of the solution are plagued by a critical vulnerability.

A code injection flaw (CVE-2015-0977) has been found in IntraVUE by Jürgen Bilberger from Daimler TSS GmbH, a security researcher who has discovered and reported vulnerabilities in several industrial control system (ICS) products over the past years.

According to an advisory from ICS-CERT, a remote, unauthenticated attacker can exploit the vulnerability to execute arbitrary operating system commands that could impact the availability, integrity, and confidentiality of affected servers.

This is a high-severity vulnerability with a CVSS base score of 10. Even an attacker with low skill could leverage the bug, but there is no evidence that an exploit is publicly available, ICS-CERT noted.

The security hole affects all Windows versions of IntraVUE prior to 2.3.0a14. The issue has been addressed with the release of IntraVUE 2.3.0a14 on February 9. In the meantime, Network Vision also released version 2.3.0a16, which brings some functionality improvements.

“It is recommended that the new version be applied as soon as possible. Users who have software support contracts with Network Vision can upgrade to the newest version at no cost,” reads the advisory from ICS-CERT.

Network Vision is a Newburyport, Massachusetts-based company that provides industrial Ethernet solutions for sectors such as automation, critical manufacturing, transportation, and water systems.

IntraVUE, the company’s flagship product, is designed to provide Ethernet device visualization and enable organizations to quickly identify issues affecting devices deployed in distributed and hostile environments. The solution can be used to identify duplicate MAC and IP addresses, connection or application faults, device or cable moves, and unauthorized connections.
