CISA Alerts on Critical Security Vulnerabilities

CISA Alerts on Critical Security Vulnerabilities

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.

At the 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.

Piotr Bazydlo and an anonymous security researcher have been credited with discovering and reporting the shortcomings to CISA.

“Successful exploitation of these vulnerabilities could allow an attacker to potentially perform remote code execution on the target system/device or crash the software,” CISA noted.

Users are advised to update to versions 11.0.6, 11.1.6, 11.2.7, 12.0.5, 12.1.6, and 13.0.2 to mitigate potential threats. ThinManager ThinServer versions 6.x – 10.x are retired, requiring that users upgrade to a supported version.

As workarounds, it is also recommended that remote access of port 2031/TCP is limited to known thin clients and ThinManager servers.
