RUGGEDCOM ROX MX5000: Cross-Site Request Forgery

Published Updated By the CyberSecBulletin desk

CVE-2022-29561 is a high-severity cross-site request forgery vulnerability in RUGGEDCOM ROX MX5000 from Siemens, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. The record lists version V2.16.0 as the first without the flaw, so updating RUGGEDCOM ROX MX5000 to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.28% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update RUGGEDCOM ROX MX5000 to V2.16.0 or a later version.
  2. Update RUGGEDCOM ROX MX5000RE to V2.16.0 or a later version.
  3. Update RUGGEDCOM ROX RX1400 to V2.16.0 or a later version.
  4. Read the advisory on cert-portal.siemens.com for workarounds and exact fixed builds.
  5. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
  6. Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description

A vulnerability has been identified in RUGGEDCOM ROX MX5000 (All versions < V2.16.0), RUGGEDCOM ROX MX5000RE (All versions < V2.16.0), RUGGEDCOM ROX RX1400 (All versions < V2.16.0), RUGGEDCOM ROX RX1500 (All versions < V2.16.0), RUGGEDCOM ROX RX1501 (All versions < V2.16.0), RUGGEDCOM ROX RX1510 (All versions < V2.16.0), RUGGEDCOM ROX RX1511 (All versions < V2.16.0), RUGGEDCOM ROX RX1512 (All versions < V2.16.0), RUGGEDCOM ROX RX1524 (All versions < V2.16.0), RUGGEDCOM ROX RX1536 (All versions < V2.16.0), RUGGEDCOM ROX RX5000 (All versions < V2.16.0). The web interface of the affected devices are vulnerable to Cross-Site Request Forgery attacks. By tricking an authenticated victim user to click a malicious link, an attacker could perform arbitrary actions on the device on behalf of the victim user.

Source: the CVE record as published by its numbering authority, via NVD and CVE.org.

The underlying weakness: Cross-Site Request Forgery

The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.

How developers prevent this class of flaw

  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. For example, use anti-CSRF packages such as the OWASP CSRFGuard. Another example is the ESAPI Session Management control, which includes a component for CSRF.
  • Ensure that the application is free of cross-site scripting issues (CWE-79), because most CSRF defenses can be bypassed using attacker-controlled script.
  • Generate a unique nonce for each form, place the nonce into the form, and verify the nonce upon receipt of the form. Be sure that the nonce is not predictable (CWE-330).
