Summary
PEPPERL+FUCHS: Profinet Gateway LB8122A.1.EL – Device is affected by XSS vulnerability and information disclosure
Notes
Summary: A stored cross-site scripting vulnerability has been discovered in the profinet gateway LB8122A.1.EL. An attacker can write an HTML tag with up to 32 characters in the message field of a HART transmitter. The HTML tag is interpreted as HTML when the HART information is displayed in a webbrowser. If the HTML tag contains a link to a manipulated page, a user can be tricked into accessing this page. Furthermore, an attacker can access information about running processes via the SNMP protocol. Sending such SNMP read commands can also trigger a reboot.
Impact: An unauthenticated attacker can use a stored HTML link in a HART transmitter to redirect a user to a manipulated website. From there, he can manipulate the user's device or environment. An attacker can collect information via SNMP to launch attacks. Sending the read commands can trigger a reboot of the device.
Remediation: Please install the updated firmware V1.3.13.
Mitigation: The web server is switched off by default and can only be switched on via the gateway display. It is then active for 5 minutes and switches itself off again. - Ensure that only authorized personnel have access to the gateway. - Only use the gateway in an isolated network environment.
CVE-2025-1985

Due to improper neutralization of input during web page generation (XSS) an unauthenticated remote attacker can inject HTML code into the Web-UI in the affected device.

6.1 (Medium)
CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Vendor Fix Please install the updated firmware V1.3.13.
CVE-2025-41654

An unauthenticated remote attacker can access information about running processes via the SNMP protocol. The amount of returned data can trigger a reboot by the watchdog.

8.2 (High)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H
CWE-306 - Missing Authentication for Critical Function
Vendor Fix Please install the updated firmware V1.3.13.
CVE-2025-41655

An unauthenticated remote attacker can access a URL which causes the device to reboot.

7.5 (High)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
CWE-306 - Missing Authentication for Critical Function
Vendor Fix Please install the updated firmware V1.3.13.
