CVE-2025-14259 identifies a SQL injection vulnerability in Jihai Jshop MiniProgram Mall System version 2.9.0, specifically affecting the /index.php/api.html endpoint. The vulnerability arises from improper sanitization of the cat_id parameter, which an attacker can manipulate to inject malicious SQL queries. This injection flaw allows remote attackers to execute arbitrary SQL commands on the backend database without requiring authentication or user interaction, increasing the attack surface significantly. The vulnerability has a CVSS 4.0 base score of 5.3, classified as medium severity, reflecting moderate impact and ease of exploitation. The vendor was notified but has not issued a patch or response, and public exploit code is available, which raises the risk of active exploitation. The flaw can lead to unauthorized data access, modification, or deletion, potentially compromising confidentiality, integrity, and availability of the affected systems. Since the vulnerability is in an e-commerce mini program system, attackers could extract sensitive customer data, manipulate product listings, or disrupt service availability. The lack of authentication requirement and remote exploitability make this a critical concern for organizations running this software, especially if exposed to the internet. The vulnerability's exploitation does not require user interaction, further simplifying attack execution. No official patches or mitigations have been released, increasing urgency for organizations to implement compensating controls.

For European organizations using Jihai Jshop MiniProgram Mall System 2.9.0, this vulnerability poses significant risks. Exploitation can lead to unauthorized disclosure of sensitive customer and business data, undermining confidentiality. Attackers could alter or delete critical e-commerce data, impacting data integrity and potentially causing financial losses or reputational damage. Availability may also be affected if attackers execute destructive SQL commands or cause database corruption. Given the public availability of exploit code and lack of vendor response, the threat of exploitation is elevated. Organizations with internet-facing instances are particularly vulnerable. The impact is amplified in sectors with stringent data protection regulations like GDPR, where breaches can result in heavy fines and legal consequences. Additionally, e-commerce platforms are attractive targets for cybercriminals aiming to steal payment information or disrupt business operations. The medium severity score suggests moderate but non-trivial risk, warranting prompt attention. Failure to address this vulnerability could lead to data breaches, loss of customer trust, and operational disruptions.

1. Immediate implementation of input validation and sanitization for the cat_id parameter to prevent SQL injection. 2. Refactor the affected code to use parameterized queries or prepared statements, eliminating direct concatenation of user input into SQL commands. 3. Deploy Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the vulnerable endpoint. 4. Restrict access to the /index.php/api.html endpoint via network segmentation or IP whitelisting where feasible. 5. Conduct thorough code audits and penetration testing to identify and remediate similar injection flaws in other parts of the application. 6. Monitor logs and network traffic for suspicious activities indicative of SQL injection exploitation attempts. 7. Engage with the vendor or community to seek official patches or updates and apply them promptly once available. 8. Consider migrating to alternative, actively maintained e-commerce platforms if vendor support remains absent. 9. Educate development teams on secure coding practices to prevent future injection vulnerabilities. 10. Backup databases regularly and ensure recovery procedures are tested to mitigate potential data loss from exploitation.
