Deeper analysis
CVE-2025-9140 is a SQL injection vulnerability affecting Shanghai Lingdang Information Technology's Lingdang CRM software versions up to 8.6.4.7. The issue resides in the file /crm/crmapi/erp/tabdetail_moduleSave.php, where manipulation of the getvaluestring argument enables injection. This flaw is classified under CWE-74 (Improper Neutralization of Special Elements used in an SQL Command) and CWE-89 (SQL Injection), with a CVSS v3.1 base score of 6.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L).
Attackers with low-privilege access (PR:L) can exploit this vulnerability remotely over the network with low complexity and no user interaction required. Successful exploitation allows limited impacts on confidentiality, integrity, and availability, potentially enabling unauthorized data access, modification, or disruption within the CRM database.
Advisories recommend upgrading to Lingdang CRM version 8.6.5.4 or later, where the vendor addressed all SQL injection vectors through parameterized queries and input sanitization. References including VulDB entries and an Exploit-DB listing (exploit-db.com/exploits/52420) confirm the public availability of a proof-of-concept exploit.
