The vulnerability CVE-2024-58290 affects Elements Xhibiter NFT Marketplace version 1.10.2 and is classified as a SQL injection (CWE-89) flaw in the collections endpoint. The issue arises from improper neutralization of special elements in SQL commands, specifically through the 'id' parameter, which is not properly sanitized. This allows attackers to craft malicious payloads that manipulate SQL queries executed by the backend database. Exploitation techniques include boolean-based, time-based, and UNION-based SQL injection, enabling attackers to extract sensitive information, modify data, or potentially escalate further attacks. The vulnerability is remotely exploitable over the network without requiring authentication or user interaction, increasing its risk profile. The CVSS 4.0 score of 9.3 reflects critical severity due to high impact on confidentiality and integrity, ease of exploitation, and broad attack surface. Although no public exploits are reported yet, the NFT marketplace context heightens the threat due to the value of digital assets and user data involved. The lack of available patches necessitates immediate attention to mitigation strategies to prevent exploitation.

For European organizations, exploitation of this vulnerability could lead to unauthorized disclosure of sensitive user data, including wallet information, transaction histories, and personal identifiers. Attackers could manipulate marketplace data, potentially altering NFT ownership records or transaction details, undermining trust and causing financial losses. Given the growing adoption of NFT platforms in Europe, such breaches could damage reputations and lead to regulatory penalties under GDPR for inadequate data protection. The critical severity and network-level exploitability mean attackers can compromise systems remotely without credentials, increasing the risk of widespread attacks. Additionally, manipulation of marketplace data could facilitate fraud or theft of digital assets, impacting both users and platform operators. The absence of known exploits currently provides a window for proactive defense, but the threat remains significant due to the high-value nature of NFT marketplaces.

European organizations using Xhibiter NFT Marketplace 1.10.2 should immediately implement input validation and sanitization on the 'id' parameter to prevent injection of malicious SQL code. Employing parameterized queries or prepared statements is essential to neutralize special characters in SQL commands. Network-level protections such as Web Application Firewalls (WAFs) configured to detect and block SQL injection patterns can provide interim defense. Monitoring database query logs for unusual patterns or delays indicative of time-based SQL injection attempts is recommended. Organizations should engage with the vendor for patches or updates and consider temporary disabling or restricting access to the vulnerable endpoint if feasible. Conducting security audits and penetration testing focused on injection flaws will help identify other potential weaknesses. Finally, educating developers on secure coding practices and integrating automated scanning tools into the development lifecycle will reduce future risks.
