CVE-2022-45278 is a high-severity SQL injection vulnerability identified in Jizhicms version 2.3.3, specifically affecting the /index.php/admins/Fields/get_fields.html component. SQL injection (CWE-89) vulnerabilities occur when untrusted input is improperly sanitized and directly incorporated into SQL queries, allowing attackers to manipulate the database queries executed by the application. In this case, the vulnerability allows an attacker with at least low-level privileges (PR:L) to remotely exploit the system over the network (AV:N) without requiring user interaction (UI:N). The vulnerability impacts confidentiality, integrity, and availability (C:H/I:H/A:H) of the affected system, enabling attackers to extract sensitive data, modify or delete database records, or disrupt service availability. The CVSS 3.1 base score of 8.8 reflects the critical nature of this flaw. Although no public exploits are currently known in the wild, the ease of exploitation combined with the high impact makes this a significant threat. The lack of vendor or product details beyond Jizhicms v2.3.3 limits the scope of direct attribution, but the vulnerability resides in a web-based content management system component, which is commonly used for managing website content and administrative functions. Attackers could leverage this flaw to gain unauthorized access to backend databases, potentially leading to data breaches or full system compromise.

For European organizations using Jizhicms v2.3.3, this vulnerability poses a substantial risk. Exploitation could lead to unauthorized disclosure of sensitive information, including personal data protected under GDPR, resulting in regulatory penalties and reputational damage. The ability to alter or delete database content threatens data integrity and operational continuity, potentially disrupting business processes reliant on the CMS. Availability impacts could cause website downtime, affecting customer trust and revenue streams. Given the administrative nature of the vulnerable component, attackers might escalate privileges or pivot to other internal systems, amplifying the breach impact. Organizations in sectors with stringent data protection requirements, such as finance, healthcare, and government, are particularly vulnerable. The absence of known exploits suggests a window for proactive mitigation, but the high CVSS score indicates that once exploited, the consequences could be severe.

1. Immediate patching is recommended; however, no official patch links are currently available. Organizations should monitor vendor communications for updates or consider upgrading to a later, unaffected version if available. 2. Implement Web Application Firewalls (WAFs) with rules specifically designed to detect and block SQL injection attempts targeting the /index.php/admins/Fields/get_fields.html endpoint. 3. Conduct thorough input validation and sanitization on all user-supplied data, especially in administrative interfaces. 4. Restrict access to the vulnerable component by IP whitelisting or VPN-only access to reduce exposure. 5. Employ database user accounts with the least privileges necessary to limit the impact of potential SQL injection exploitation. 6. Perform regular security audits and penetration testing focused on injection flaws. 7. Monitor logs for unusual database queries or errors indicative of injection attempts. 8. Educate administrators on recognizing signs of compromise and enforce strong authentication mechanisms to prevent unauthorized access. 9. Consider deploying runtime application self-protection (RASP) tools that can detect and block injection attacks in real-time.
