As many as five vulnerabilities have been uncovered in Ovarro’s TBox remote terminal units (RTUs) that, if left unpatched, could open the door for escalating attacks against critical infrastructures, like remote code execution and denial-of-service.

“Successful exploitation of these vulnerabilities could result in remote code execution, which may cause a denial-of-service condition,” the U.S. Cybersecurity and Infrastructure Security Agency (CISA) said in an advisory published on March 23.
