Apache CloudStack: Cross-Site Request Forgery

CVE-2024-45693 is a high-severity cross-site request forgery vulnerability in Apache CloudStack from Apache, 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. Affected Apache CloudStack versions: 4.15.1.0 through 4.18.2.3; 4.19.0.0 through 4.19.1.1. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.55% 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. Check which version of Apache CloudStack you run against the affected versions below, and install the vendor's latest release.
  2. Read the advisory on cloudstack.apache.org for workarounds and exact fixed builds.
  3. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
  4. 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

Users logged into the Apache CloudStack's web interface can be tricked to submit malicious CSRF requests due to missing validation of the origin of the requests. This can allow an attacker to gain privileges and access to resources of the authenticated users and may lead to account takeover, disruption, exposure of sensitive data and compromise integrity of the resources owned by the user account that are managed by the platform. This issue affects Apache CloudStack from 4.15.1.0 through 4.18.2.3 and 4.19.0.0 through 4.19.1.1 Users are recommended to upgrade to Apache CloudStack 4.18.2.4 or 4.19.1.2, or later, which addresses this issue.

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).
