CVE-2024-41628 is a directory traversal vulnerability identified in Severalnines ClusterControl, a popular database management and automation platform. The affected versions include all releases before 1.9.8-9778, 2.0.0-9779, and 2.1.0-9780. The vulnerability resides in the CMON API, which is used for cluster monitoring and management. An attacker can exploit this flaw by sending specially crafted HTTP requests that manipulate file path parameters to traverse directories outside the intended scope. This allows the attacker to read arbitrary files on the server, potentially exposing sensitive configuration files, credentials, or other critical data. The vulnerability does not require any authentication or user interaction, making it remotely exploitable over the network. The weakness is classified under CWE-22 (Improper Limitation of a Pathname to a Restricted Directory), indicating insufficient validation of user-supplied file paths. Although no exploits have been observed in the wild yet, the high CVSS score (7.5) highlights the serious confidentiality impact and the low attack complexity. The vulnerability does not affect integrity or availability directly but can facilitate further attacks if sensitive information is disclosed. The lack of patches at the time of this report means organizations must rely on mitigating controls until updates are released.

The primary impact of CVE-2024-41628 is the unauthorized disclosure of sensitive information due to arbitrary file read capabilities. Attackers can access configuration files, database credentials, or other sensitive data stored on the server, which can lead to further compromise such as privilege escalation or lateral movement within the network. For organizations relying on Severalnines ClusterControl to manage critical database infrastructure, this breach of confidentiality can undermine trust, cause data leaks, and potentially violate compliance requirements. Since the vulnerability is remotely exploitable without authentication, it significantly increases the attack surface for threat actors. Although the vulnerability does not directly compromise system integrity or availability, the information gained can be leveraged to launch more damaging attacks. The absence of known exploits in the wild currently reduces immediate risk, but the ease of exploitation and high impact score suggest that attackers may develop exploits soon, especially targeting organizations with exposed management interfaces.

1. Immediately restrict access to the CMON API by implementing network-level controls such as IP whitelisting, VPN access, or firewall rules to limit exposure to trusted administrators only. 2. Monitor and log all access to the CMON API for unusual or suspicious requests that may indicate exploitation attempts. 3. Apply the official patches or updates from Severalnines as soon as they become available to remediate the vulnerability. 4. If patching is not immediately possible, consider deploying a web application firewall (WAF) with custom rules to detect and block directory traversal patterns in HTTP requests targeting the CMON API. 5. Conduct a thorough audit of server files and credentials to identify any potential data exposure resulting from this vulnerability. 6. Educate system administrators on the risks of exposing management interfaces publicly and enforce the principle of least privilege for API access. 7. Regularly update and harden the underlying operating system and services hosting ClusterControl to reduce the attack surface.
