PRODUCT DESCRIPTION

SIMATIC S7-1200 CPU products have been designed for discrete and continuous control in industrial environments such as manufacturing, food and beverages, and chemical industries worldwide.

SIPLUS extreme products are designed for reliable operation under extreme conditions and are based on SIMATIC, LOGO!, SITOP, SINAMICS, SIMOTION, SCALANCE or other devices. SIPLUS devices use the same firmware as the product they are based on.

VULNERABILITY DESCRIPTION

Un-/Collapse All

This chapter describes all vulnerabilities (CVE-IDs) addressed in this security advisory. Wherever applicable, it also documents the product-specific impact of the individual vulnerabilities.

Vulnerability CVE-2024-47100

The web interface of the affected devices is vulnerable to Cross-Site Request Forgery (CSRF) attacks. This could allow an unauthenticated attacker to change the CPU mode by tricking a legitimate and authenticated user with sufficient permissions on the target CPU to click on a malicious link.
