CVE-2024-24375 is a SQL injection vulnerability identified in Jfinalcms version 5.0.0, specifically targeting the /admin/admin name parameter. SQL injection (CWE-89) occurs when untrusted input is improperly sanitized, allowing attackers to inject malicious SQL queries. This vulnerability enables remote attackers to retrieve sensitive information from the backend database without requiring authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The vulnerability impacts confidentiality (C) but does not affect integrity (I) or availability (A). The weakness is related to improper handling of input parameters in the administrative interface, which is typically a high-value target. Although no exploits are currently known in the wild, the low attack complexity and network accessibility make it a significant threat. The vulnerability is categorized under CWE-312 (Cleartext Storage of Sensitive Information) and CWE-89 (SQL Injection), highlighting risks around data exposure and injection flaws. No official patches have been released, increasing the urgency for defensive measures. The vulnerability was published on March 7, 2024, with a CVSS 3.1 score of 7.5, reflecting high severity due to ease of exploitation and potential data leakage.

The primary impact of CVE-2024-24375 is unauthorized disclosure of sensitive data stored in the backend database of Jfinalcms installations. This can include user credentials, personal information, or configuration details, which attackers can leverage for further attacks or identity theft. Since the vulnerability does not affect integrity or availability, it does not allow data modification or service disruption directly. However, the exposure of sensitive information can lead to secondary impacts such as privilege escalation, targeted phishing, or lateral movement within affected networks. Organizations relying on Jfinalcms 5.0.0 for content management, especially those hosting sensitive or regulated data, face increased risk of data breaches and compliance violations. The ease of exploitation without authentication broadens the attack surface, potentially enabling widespread scanning and automated attacks. The lack of known exploits in the wild currently limits immediate threat but does not reduce the urgency for mitigation, as public disclosure often leads to rapid development of exploit code.

1. Immediate deployment of web application firewalls (WAFs) with rules to detect and block SQL injection attempts targeting the /admin/admin endpoint. 2. Implement strict input validation and parameterized queries or prepared statements in the affected codebase to prevent injection of malicious SQL. 3. Restrict access to the administrative interface by IP whitelisting or VPN-only access to reduce exposure. 4. Monitor server and application logs for unusual query patterns or repeated access attempts to the vulnerable parameter. 5. Conduct a thorough security audit of all input handling in Jfinalcms and related components to identify and remediate similar injection flaws. 6. Stay updated with vendor advisories for official patches or updates and apply them promptly once available. 7. Consider temporary disabling or restricting the /admin/admin functionality if feasible until a patch is released. 8. Educate development and operations teams on secure coding practices to prevent recurrence of injection vulnerabilities.
