GS-4210-24PL4C hardware 2.0: Cross-Site Request Forgery

CVE-2024-8458 is a high-severity cross-site request forgery vulnerability in GS-4210-24PL4C hardware 2.0 from PLANET Technology, 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 2.305b240719 as the first without the flaw, so updating GS-4210-24PL4C hardware 2.0 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 GS-4210-24PL4C hardware 2.0 to 2.305b240719 or a later version.
  2. Update GS-4210-24P2S hardware 3.0 to 3.305b240802 or a later version.
  3. Update gs-4210-24pl4c_hardware_3.0 to 3.305b240802 or a later version.
  4. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
  5. 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

Certain switch models from PLANET Technology have a web application that is vulnerable to Cross-Site Request Forgery (CSRF). An unauthenticated remote attacker can trick a user into visiting a malicious website, allowing the attacker to impersonate the user and perform actions on their behalf, such as creating accounts.

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).
