CVE-2024-3624 identifies a vulnerability in the Quay container registry's mirror-registry component, specifically in how it stores database credentials. The flaw involves storing the database password in plaintext within the jinja templated config.yaml file. This insecure storage means that any malicious actor who gains access to this configuration file can retrieve the database password without needing to bypass encryption or other protections. The vulnerability requires the attacker to have at least limited privileges (PR:L) and network or local access (AV:A), but no user interaction is needed (UI:N). The vulnerability impacts confidentiality and integrity severely (C:H/I:H) but does not affect availability (A:N). The CVSS 3.1 base score is 7.3, reflecting a high severity level. While no known exploits have been reported in the wild, the risk remains significant due to the sensitive nature of database credentials and the potential for lateral movement or data exfiltration. The vulnerability was published on April 25, 2024, and assigned by Red Hat. No patches or mitigations were provided at the time of reporting, emphasizing the need for immediate manual mitigation steps. This issue highlights the importance of secure credential storage practices, such as encryption or use of secret management tools, especially in containerized and cloud-native environments.

The primary impact of CVE-2024-3624 is the compromise of confidentiality and integrity of Quay's database. An attacker who accesses the plaintext password can connect to the database, potentially extracting sensitive data, modifying records, or escalating privileges within the environment. This can lead to data breaches, unauthorized changes to container images or metadata, and disruption of supply chain security. Although availability is not directly affected, the downstream effects of data manipulation or exposure can cause operational disruptions and loss of trust. Organizations relying on Quay for container image management, especially in production or sensitive environments, face significant risk of data compromise and potential regulatory consequences. The vulnerability's requirement for some level of access means that perimeter defenses and internal access controls are critical to prevent exploitation. The absence of known exploits reduces immediate risk but does not eliminate the threat, as attackers may develop exploits given the publicly available details.

To mitigate CVE-2024-3624, organizations should immediately audit access controls to the mirror-registry's config.yaml file, ensuring only authorized personnel and processes can read it. Implement strict file system permissions and consider isolating the registry environment to limit exposure. Until an official patch is released, manually remove or encrypt plaintext passwords in configuration files, leveraging secret management solutions such as HashiCorp Vault, Kubernetes Secrets, or similar tools to inject credentials securely at runtime. Monitor logs and network traffic for suspicious access patterns to the registry and database. Employ network segmentation to restrict access to the database from untrusted sources. Regularly rotate database credentials and update configurations accordingly. Additionally, keep abreast of vendor advisories for patches or updates addressing this vulnerability and apply them promptly once available. Conduct security training to raise awareness about secure credential handling among DevOps and security teams.
