CVE-2025-41669
Description
The Web-based Management allows a remote low privileged Engineer user to install additional APPs on the device downloaded from the PLCnext Store without implementing any data verification mechanism, leading to the capability for an Engineer user to reach arbitrary code execution with root privileges on the PLC device. A successful exploitation may allow to install a manipulated APP package, potentially impacting integrity and availability of the PLCnext Control.
AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
A low-privileged Engineer can install unverified APPs from the PLCnext Store, leading to arbitrary code execution with root privileges on PLCnext Control devices.
Vulnerability
The Web-based Management in PLCnext firmware versions prior to 2026.0.3 allows a remote low-privileged Engineer user to install additional APPs from the PLCnext Store without any data verification mechanism, enabling the installation of manipulated APP packages [1].
Exploitation
An attacker with Engineer user credentials can access the Web-based Management, download and install a crafted APP from the store. The lack of verification allows the malicious APP to be installed, leading to arbitrary code execution with root privileges [1].
Impact
Successful exploitation allows the attacker to execute arbitrary code with root privileges on the PLCnext Control device, compromising integrity and availability [1].
Mitigation
The vulnerability is fixed in PLCnext firmware version 2026.0.3 [1]. Users should update to this version or later to mitigate the issue.
