UK-based industrial automation company Ovarro recently patched a series of vulnerabilities in its TBox remote terminal units (RTUs). Cybersecurity experts say these flaws could pose a serious risk to organizations.
Ovarro’s TBox RTUs are described by the vendor as a remote telemetry solution for remote automation and monitoring of critical assets. These devices are used worldwide, including in the water, oil and gas, power, transportation and process industries.
Researchers at industrial cybersecurity firm Claroty discovered last year that the TBox RTUs, as well as the associated TWinSoft engineering software, are affected by five types of vulnerabilities.
Information about the vulnerabilities — all of which have been rated “high severity” — is available in a blog post published by Claroty and advisories released by the U.S. Cybersecurity and Infrastructure Security Agency (CISA) and Ovarro.

The vulnerabilities can allow an attacker to bypass protection features, cause a denial-of-service (DoS) condition, and execute arbitrary code on a targeted device.
“The risks associated with these flaws threaten not only the integrity of automation processes, but also, in some cases public safety,” Claroty said in its blog post. “Using these security shortcomings, we were able to find web-based interfaces, similar to HMIs, that monitor process levels and other industrial activity. We’ve seen in the past what could go wrong when s ..
