Vulnerability from csaf_wagogmbhcokg - Published: 2024-03-13 08:30 - Updated: 2024-03-13 08:30Summary
Wago: Multiple vulnerabilities in web-based management of multiple products
Notes
Summary: The Web-Based Management (WBM) of WAGOs programmable logic controller (PLC) is typically used for administration, commissioning, and updates.
The option to change the configuration data via tools or the web-based-management enabled attackers to prepare cross-site-scripting attacks and under specific circumstances perform remote code execution.
Impact: The web-based management of affected products is vulnerable to Reflective Cross-Site Scripting. This can be used to install malicious code and to gain access to confidential information on a System that connects to the WBM after it has been compromised.
Additionally, the affected products contain a buffer overflow vulnerability which enables attackers to remotely execute code, which could lead to compromise of data and execution of malicious code.
Mitigation: If not needed, you can deactivate the web-based management to prevent attacks (command line). Disableunused TCP/UDP-ports. Restrict network access to the device. Do not directly connect the device to theinternet.
Remediation: A fix for the affected firmwares will be provided with the following firmware versions:
- FW14 installed on 750-352/xxx-xxx
- FW14 installed on 750-88x/xxx-xxx
- FW14 installed on 750-852
No fix planned for products:
<= FW13 installed on 750-831/xxx-xxx
<= FW13 installed on 750-829
An unautheticated remote attacker could send specifically crafted packets to a affected device. If an authenticated user then views that data in a specific page of the web-based management a buffer overflow will be triggered to gain full access of the device.
8.8 (High)
Mitigation
If not needed, you can deactivate the web-based management to prevent attacks (command line). Disableunused TCP/UDP-ports. Restrict network access to the device. Do not directly connect the device to theinternet.
Vendor Fix
A fix for the affected firmwares will be provided with the following firmware versions:
- FW14 installed on 750-352/xxx-xxx
- FW14 installed on 750-88x/xxx-xxx
- FW14 installed on 750-852
No fix planned for products:
<= FW13 installed on 750-831/xxx-xxx
<= FW13 installed on 750-829
An unauthenticated remote attacker can use an XSS attack due to improper neutralization of input during web page generation. User interaction is required. This leads to a limited impact of confidentiality and integrity but no impact of availability.
5.4 (Medium)
Mitigation
If not needed, you can deactivate the web-based management to prevent attacks (command line). Disableunused TCP/UDP-ports. Restrict network access to the device. Do not directly connect the device to theinternet.
Vendor Fix
