Summary
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has issued warnings regarding multiple vulnerabilities in industrial control systems (ICS) related to Siemens, Schneider Electric, and ABB equipment. The advisories, released on April 23, 2025, detail critical flaws that could pose significant risks to essential infrastructure across various sectors, including energy and transportation.
Specific vulnerabilities include issues that could allow attackers to initiate denial-of-service conditions, execute unwanted code, and expose sensitive information. CISA recommends immediate updates and mitigations to safeguard against these threats.
Key Points
- CISA issued five advisories focusing on critical vulnerabilities in ICS hardware from Siemens, Schneider Electric, and ABB.
- Siemens’ TeleControl Server Basic was found to have an SQL Injection vulnerability, allowing potential unauthorised access to databases.
- Schneider Electric’s Wiser Home Controller could expose sensitive credentials due to improper information handling.
- ABB’s MV Drives equipment contains vulnerabilities that might enable complete access to the drive, risking denial-of-service scenarios.
- Recommended actions include restricting access to affected systems and updating to the latest firmware versions.
