CVE-2025-14011 is a SQL injection vulnerability identified in JIZHICMS, a content management system, affecting versions 2.5.0 through 2.5.5. The vulnerability resides in the commentlist function of the file /index.php/admins/Comment/addcomment.html, specifically in the Add Display Name Field component. The issue arises due to improper sanitization or validation of the aid and tid parameters, which are used in SQL queries without adequate escaping or parameterization. This allows an attacker to inject malicious SQL code remotely, without requiring user interaction or authentication, although the CVSS vector indicates a high privilege requirement, suggesting exploitation might need elevated access within the system. Successful exploitation can lead to unauthorized data access, modification, or deletion, impacting the confidentiality, integrity, and availability of the backend database. The vendor was contacted early but did not respond or provide a patch, and a public exploit has been released, increasing the risk of exploitation. The CVSS 4.0 base score is 5.1 (medium severity), reflecting the moderate impact and exploitation complexity. No known exploits are reported in the wild yet, but the public availability of exploit code increases the likelihood of attacks. The vulnerability affects a widely used CMS component, making it relevant for organizations relying on JIZHICMS for web content management.

The SQL injection vulnerability could allow attackers to execute arbitrary SQL commands on the backend database, potentially leading to unauthorized data disclosure, data manipulation, or deletion. This compromises the confidentiality and integrity of sensitive information stored within the CMS database, such as user comments, administrative data, or other content. Availability could also be affected if destructive queries are executed. Given the remote exploitation capability without user interaction, attackers can target vulnerable systems over the internet. However, the requirement for high privileges to exploit somewhat limits the attack surface to insiders or compromised accounts with elevated rights. Organizations using JIZHICMS in sectors such as government, education, or business that rely on this CMS for critical web services may face data breaches, reputational damage, and operational disruptions. The lack of vendor response and patch availability increases exposure time, raising the risk of exploitation by threat actors leveraging the public exploit code.

Organizations should immediately audit their JIZHICMS installations to identify affected versions (2.5.0 to 2.5.5). Since no official patch is available, implement the following mitigations: 1) Apply manual input validation and sanitization on the aid and tid parameters in the commentlist function to prevent injection, using parameterized queries or prepared statements. 2) Restrict access to the /index.php/admins/Comment/addcomment.html endpoint to trusted administrators or internal networks via firewall rules or VPN. 3) Monitor web server and database logs for suspicious SQL query patterns or unusual activity targeting these parameters. 4) Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts on the affected endpoints. 5) Limit database user privileges associated with the CMS to the minimum necessary to reduce impact if exploited. 6) Consider upgrading to a newer, unaffected CMS version once available or migrating to alternative CMS platforms with active security support. 7) Maintain regular backups of CMS data to enable recovery in case of compromise. These steps provide layered defense until an official patch is released.
