CVE-2025-4510 is a SQL Injection vulnerability identified in Changjietong UFIDA CRM version 1.0. The vulnerability resides in the handling of the 'gblOrgID' parameter within the /optnty/optntyday.php file. An attacker can remotely manipulate this parameter to inject malicious SQL code, potentially altering database queries executed by the application. This can lead to unauthorized data access, data modification, or even deletion, depending on the privileges of the database user. The vulnerability requires no user interaction and no authentication, making it accessible to unauthenticated remote attackers. The CVSS 4.0 base score is 5.3, categorized as medium severity, reflecting that while the attack vector is network-based and requires low complexity, the impact on confidentiality, integrity, and availability is limited to low levels. The vendor has not responded to early notifications, and no patches or mitigations have been published yet. Although no known exploits are currently in the wild, the public disclosure increases the risk of exploitation attempts. The vulnerability affects only version 1.0 of the UFIDA CRM product, which is a customer relationship management system developed by Changjietong, likely used in enterprise environments to manage customer data and interactions.

For European organizations using Changjietong UFIDA CRM 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of their customer data. Successful exploitation could lead to unauthorized access to sensitive customer information, manipulation of CRM data, and potential disruption of business operations. This could result in reputational damage, regulatory non-compliance (especially under GDPR), and financial losses. Since the vulnerability allows remote exploitation without authentication, attackers can target exposed CRM instances over the internet or internal networks. The lack of vendor response and absence of patches increases the window of exposure. Organizations relying on this CRM for critical customer management functions may experience operational disruptions if attackers modify or delete data. Additionally, attackers could leverage the vulnerability as a foothold for further lateral movement within the network, escalating the impact beyond the CRM system itself.

Given the absence of official patches, European organizations should implement immediate compensating controls. These include restricting network access to the CRM system by implementing strict firewall rules and VPN requirements to limit exposure to trusted users only. Input validation and web application firewalls (WAFs) should be configured to detect and block SQL injection attempts targeting the 'gblOrgID' parameter. Regular monitoring of logs for suspicious query patterns or anomalous database activity is essential. Organizations should also consider deploying database activity monitoring tools to detect unauthorized queries. If possible, isolating the CRM system in a segmented network zone can reduce the risk of lateral movement. Long term, organizations should engage with the vendor for patch availability or consider upgrading to a newer, supported CRM solution. Conducting a thorough security assessment of the CRM environment and applying principle of least privilege to database accounts used by the application will further reduce risk.
