CVE-2024-22030

Summary

A vulnerability within Rancher has been identified, which could be exploited under specific conditions via a man-in-the-middle (MITM) attack. For this to take place, an attacker must either have control over a domain that has expired or carry out a DNS spoofing or hijacking attack against the Rancher URL. This potential security flaw requires stringent measures to safeguard against domain takeover and reinforce DNS security protocols to prevent exploitation. Organizations using Rancher must remain vigilant, ensuring they regularly monitor domain statuses and assess their DNS integrity.
