CVE-2025-8219: Critical SQL Injection Found in Lingdang CRM
Lingdang CRM, a customer relationship management software, is vulnerable to a critical SQL injection flaw that could allow attackers to compromise affected systems. Let's dive into the details and how to protect yourself.
Vulnerability Details
- CVE ID: CVE-2025-8219
- Description: A SQL injection vulnerability exists in Shanghai Lingdang Information Technology Lingdang CRM up to version 8.6.4.7. An attacker can remotely exploit this vulnerability by manipulating the
getvaluestringargument in an HTTP POST request to/crm/crmapi/erp/tabdetail_moduleSave_dxkp.php. - CVSS Score: 6.3 (Medium)
- CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L
- CVSS Explanation: This means an attacker with low privileges (e.g., a standard user account) can remotely execute arbitrary SQL queries without any user interaction, potentially leading to data theft, modification, or denial of service.
- Exploit Requirements: The attacker needs network access to the vulnerable CRM instance and valid user credentials (low privilege is sufficient).
- Affected Vendor: Shanghai Lingdang Information Technology
- Affected Product: Lingdang CRM
- Affected Version: Up to 8.6.4.7
- CWE: CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection'). This occurs when user-supplied input is not properly sanitized before being used in a SQL query, allowing attackers to inject malicious SQL code.
Timeline of Events

- 2025-07-27: CVE ID assigned.
- Unknown: Vendor releases version 8.6.5.2 addressing the issue.
Exploitability & Real-World Risk
This SQL injection vulnerability poses a significant risk because it is remotely exploitable and requires only low-level user credentials. In a real-world scenario, an attacker could use stolen or compromised credentials to inject malicious SQL code, potentially gaining access to sensitive customer data, financial records, or even administrative privileges. This could lead to significant data breaches and reputational damage for organizations using vulnerable versions of Lingdang CRM.
Recommendations
- Upgrade: The most effective solution is to upgrade Lingdang CRM to version 8.6.5.2 or later. The vendor states that this version includes fixes for all known SQL injection vulnerabilities.
- Input Sanitization: If immediate upgrade is not possible, implement strict input validation and sanitization on all user-supplied data, especially the
getvaluestringparameter. - Web Application Firewall (WAF): Deploy a WAF to detect and block malicious SQL injection attempts.
- Regular Security Audits: Conduct regular security audits and penetration testing to identify and address potential vulnerabilities in your CRM system.
Technical Insight
The vulnerability lies in the improper handling of the getvaluestring parameter within the tabdetail_moduleSave_dxkp.php file. The application fails to adequately sanitize this input before using it in a SQL query. An attacker can inject malicious SQL code into this parameter, allowing them to manipulate the database.
