AI Analysis
Technical Summary
CVE-2023-51982 is a critical authentication bypass vulnerability affecting CrateDB version 5.5.1, specifically within its Admin UI component. CrateDB is a distributed SQL database management system designed for real-time analytics. The vulnerability arises when password authentication is configured alongside local address-based identity authentication. An attacker can exploit this flaw by manipulating the X-Real-IP HTTP request header to a specific value, thereby bypassing the intended authentication mechanism and gaining unauthorized access to the Admin UI. This bypass allows the attacker to assume the default user identity without providing valid credentials. The vulnerability is classified under CWE-287 (Improper Authentication), indicating a failure to properly verify user identity. The CVSS v3.1 base score of 9.8 reflects the high severity, with network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and full impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Although no known exploits in the wild have been reported yet, the ease of exploitation and critical impact make this a significant threat. The lack of available patches at the time of reporting underscores the urgency for organizations to implement mitigations and monitor for updates from CrateDB.
Potential Impact
For European organizations utilizing CrateDB 5.5.1, this vulnerability poses a severe risk. Unauthorized access to the Admin UI can lead to full compromise of the database system, including unauthorized data access, data manipulation, and potential disruption of services relying on CrateDB. Given the critical nature of the vulnerability, attackers could exfiltrate sensitive information, alter or delete data, and disrupt business operations. This is particularly concerning for sectors handling sensitive or regulated data such as finance, healthcare, telecommunications, and government agencies within Europe. The breach of confidentiality and integrity could lead to regulatory non-compliance under GDPR, resulting in legal and financial penalties. Additionally, availability impacts could disrupt critical analytics and operational processes dependent on CrateDB, affecting decision-making and service delivery.
Mitigation Recommendations
To mitigate this vulnerability, European organizations should immediately restrict access to the CrateDB Admin UI to trusted networks and IP addresses, effectively minimizing exposure to untrusted sources. Implement network-level controls such as firewalls and VPNs to limit Admin UI accessibility. Organizations should monitor and filter HTTP headers, particularly the X-Real-IP header, to prevent spoofing or manipulation by external actors. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious header values. Until an official patch is released, consider disabling the Admin UI if operationally feasible or deploying it behind strong authentication proxies that enforce multi-factor authentication (MFA). Regularly audit access logs for unusual or unauthorized access attempts. Stay informed about CrateDB security advisories and apply patches promptly once available. Additionally, conduct internal security assessments and penetration tests focusing on the Admin UI to identify and remediate potential exploitation paths.
