A vulnerability has been identified in SCALANCE X204RNA (HSR) (All versions < V3.2.7), SCALANCE X204RNA (PRP) (All versions < V3.2.7), SCALANCE X204RNA EEC (HSR) (All versions < V3.2.7), SCALANCE X204RNA EEC (PRP) (All versions < V3.2.7), SCALANCE X204RNA EEC (PRP/HSR) (All versions < V3.2.7). The integrated web server could allow Cross-Site Scripting (XSS) attacks if unsuspecting users are tricked into accessing a malicious link. This can be used by an attacker to trigger a malicious request on the affected device.
This plugin only works with Tenable.ot.

"The following text was originally created by the Cybersecurity and Infrastructure Security Agency (CISA). The original
can be found at CISA.gov.
Siemens released updates for the affected products and recommends updating to the latest versions:
- Update to V3.2.7 or later version
Siemens identified the following specific workarounds and mitigations users can apply to reduce risk:
- Restrict access to affected systems, especially to ports 22/TCP, 80/TCP, 443/TCP, and 161/UDP to only trusted IP
addresses.
- Disable the simple network management protocol (SNMP) service if not required and if the product supports disabling.
- Deactivate the webserver if not required and if the product supports deactivation.
As a general security measure, Siemens recommends protecting network access to devices with appropriate mechanisms. To
operate the devices in a protected IT environment, Siemens recommends configuring the environment according to Siemens'
operational guidelines for industrial security and following the recommendations in the product manuals.
Additional information on industrial security by Siemens can be found on the Siemens Industrial Security webpage.
For further inquiries on security vulnerabilities in Siemens products, users should contact Siemens ProductCERT.
For more information, see the associated Siemens security advisory SSA-363821 in HTML and CSAF.");
