Red Hat OpenShift Container Platform 4.12: Insufficient Entropy

Published Updated By the CyberSecBulletin desk

CVE-2024-6508 is a high-severity insufficient entropy vulnerability in Red Hat OpenShift Container Platform 4.12 from Red Hat, with a CVSS 3.1 base score of 8.0 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, but only if a user takes part, for example by opening a link or file. There is no confirmed exploitation so far. EPSS estimates a 0.67% chance of exploitation within 30 days, higher than 53% of scored CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Check which version of Red Hat OpenShift Container Platform 4.12 you run against the affected versions below, and install the vendor's latest release.
  2. 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

An insufficient entropy vulnerability was found in the Openshift Console. In the authorization code type and implicit grant type, the OAuth2 protocol is vulnerable to a Cross-Site Request Forgery (CSRF) attack if the state parameter is used inefficiently. This flaw allows logging into the victim’s current application account using a third-party account without any restrictions.

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

The underlying weakness: Insufficient Entropy

The product uses an algorithm or scheme that produces insufficient entropy, leaving patterns or clusters of values that are more likely to occur than others.

How developers prevent this class of flaw

  • Determine the necessary entropy to adequately provide for randomness and predictability. This can be achieved by increasing the number of bits of objects such as keys and seeds.
