The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has released eight Industrial Control Systems (ICS) advisories on Tuesday, warning of critical flaws affecting equipment from Delta Electronics and Rockwell Automation.
This includes 13 security vulnerabilities in Delta Electronics’ InfraSuite Device Master, a real-time device monitoring software. All versions prior to 1.0.5 are affected by the issues.
“Successful exploitation of these vulnerabilities could allow an unauthenticated attacker to obtain access to files and credentials, escalate privileges, and remotely execute arbitrary code,” CISA said.
Top of the list is CVE-2023-1133 (CVSS score: 9.8), a critical flaw that arises from the fact that InfraSuite Device Master accepts unverified UDP packets and deserializes the content, thereby allowing an unauthenticated remote attacker to execute arbitrary code.
Two other deserialization flaws, CVE-2023-1139 (CVSS score: 8.8) and CVE-2023-1145 (CVSS score: 7.8) could also be weaponized to obtain remote code execution, CISA cautioned.
Piotr Bazydlo and an anonymous security researcher have been credited with discovering and reporting the shortcomings to CISA.
