Siemens Web Server Login Page of Industrial Controllers Cross-Site Request Forgery (CVE-2022-30694)

medium Tenable OT Security Plugin ID 500715

Synopsis

The remote OT asset is affected by a vulnerability.

Description

The login endpoint /FormLogin in affected web services does not apply proper origin checking. This could allow authenticated remote attackers to track the activities of other users via a login cross- site request forgery attack.

This plugin only works with Tenable.ot.

Siemens has identified the following specific workarounds and mitigations users can apply to reduce risk:

- Do not access the product’s web service via URLs coming from untrusted sources.
- Disable the web server if possible.
- SIMATIC PC Station (Specifically): Disable the web server. Note that this feature is disabled by default.

As a general security measure, Siemens recommends protecting network access to devices with appropriate mechanisms. To operate devices in a protected IT environment, Siemens recommends configuring the environment according to Siemens’ Operational Guidelines for Industrial Security and following recommendations in the product manuals.
