JIZHICMS

Overview

CVE-2025-14012 details a SQL injection vulnerability found in JIZHICMS versions up to 2.5.5. This vulnerability affects the batch comment deletion functionality. Specifically, the functions deleteAll, findAll, and delete within the /index.php/admins/Comment/deleteAll.html file are susceptible to malicious manipulation. An attacker can leverage this flaw to execute arbitrary SQL queries on the database, potentially leading to data breaches, modification, or even complete system compromise.

Technical Details

The vulnerability stems from insufficient input sanitization within the batch comment deletion feature. The deleteAll.html component processes data parameters without proper validation, allowing an attacker to inject malicious SQL code within these parameters. The publicly disclosed exploit demonstrates how to craft a specific payload that, when passed to the affected functions, results in the execution of arbitrary SQL commands. This vulnerability is remotely exploitable, meaning an attacker doesn’t need local access to the server to launch an attack.

Affected file: /index.php/admins/Comment/deleteAll.html

Affected functions: deleteAll, findAll, delete

CVSS Analysis

This vulnerability has been assigned a CVSS score of 4.7 (Medium).

• CVSS Vector: (This vector string wasn’t provided in the prompt. A full CVSS vector is needed for a complete assessment)
• Impact: Limited data modification or access.
• Attack Vector: Network
• Attack Complexity: High (requires knowledge of SQL syntax and database structure)
• Privileges Required: None (attacker does not need credentials)
• User Interaction: None
• Scope: Unchanged
• Confidentiality Impact: Low
• Integrity Impact: Low
• Availability Impact: None

Possible Impact

Successful exploitation of CVE-2025-14012 could lead to several negative consequences, including:

• Data Breach: An attacker could extract sensitive information from the JIZHICMS database.
• Data Modification: Malicious actors might alter existing data, potentially leading to incorrect or corrupted content.
• Account Compromise: An attacker could potentially gain unauthorized access to user accounts by manipulating database entries related to authentication.
• Denial of Service (DoS): While the availability impact is rated as None, poorly crafted SQL injection attempts could potentially overload the database server, leading to a temporary denial of service.

Mitigation or Patch Steps

Unfortunately, the vendor has not responded to vulnerability disclosure attempts. Therefore, the following mitigation steps are recommended:

1. Upgrade JIZHICMS (if a patch becomes available): Continuously monitor the JIZHICMS website for any security updates or patches addressing this vulnerability. If a patch is released, apply it immediately.
2. Input Sanitization: Implement robust input sanitization and validation techniques on the deleteAll.html component, specifically for the parameters passed to the deleteAll, findAll, and delete functions. Use parameterized queries or prepared statements to prevent SQL injection.
3. Web Application Firewall (WAF): Deploy a Web Application Firewall (WAF) with rules designed to detect and block SQL injection attempts. Configure the WAF to filter potentially malicious payloads before they reach the JIZHICMS application.
4. Database Permissions: Apply the principle of least privilege to database user accounts. Ensure that the account used by JIZHICMS has only the necessary permissions to perform its intended functions, minimizing the potential damage from a successful SQL injection attack.
5. Monitor and Audit: Implement thorough monitoring and auditing of database activity. Monitor for suspicious SQL queries or unusual database access patterns that could indicate an attempted exploit.
