Summary

Multiple vulnerabilities in SIMATIC RF160B RFID readers (versions below V2.2) could allow an attacker to execute arbitrary code within the context of a privileged process. The vulnerabilities span memory corruption (CWE-119, CWE-125, CWE-190, CWE-191, CWE-787, CWE-416), insufficient input validation (CWE-20, CWE-665), weak authentication and authorization (CWE-287, CWE-862, CWE-863), insecure cryptography (CWE-326, CWE-330, CWE-295), and other issues (CWE-74, CWE-116, CWE-120, CWE-502, CWE-610, CWE-681, CWE-668, CWE-281, CWE-835, CWE-1188, and others). The affected device is the SIMATIC RF160B firmware versions below V2.2.

What this means

What could happen

An attacker could execute arbitrary code on the SIMATIC RF160B reader with elevated privileges, potentially allowing them to modify RFID read/write operations, alter process data, or disrupt industrial processes that depend on RFID identification and authentication.

Who's at risk

Manufacturing facilities and warehouses using Siemens SIMATIC RF160B RFID readers for product identification, tracking, and authentication in automated processes. This includes discrete manufacturing, food/beverage production, and logistics operations where RFID-based process control is critical.

How it could be exploited

An attacker with network access to the SIMATIC RF160B can send specially crafted requests that exploit memory corruption or input validation weaknesses to inject and execute arbitrary code in a privileged process context. The vulnerability is remotely exploitable without requiring authentication or user interaction.
