CVE-2025-15496 identifies a SQL injection vulnerability in the yshopmall e-commerce platform developed by guchengwuyue, specifically affecting versions 1.9.0 and 1.9.1. The vulnerability exists in the getPage function within the /api/jobs endpoint, where the 'sort' parameter is improperly handled, allowing an attacker to inject malicious SQL code. This injection flaw can be exploited remotely without requiring authentication or user interaction, making it accessible to a wide range of attackers. The vulnerability has a CVSS 4.0 base score of 5.3, indicating medium severity, with low complexity and no privileges required for exploitation. The impact includes potential unauthorized access to sensitive data, data manipulation, or disruption of service availability. Despite early reporting to the vendor, no patch or official response has been issued, and no known exploits have been observed in the wild yet. The lack of vendor response increases the risk as attackers may develop exploits over time. The vulnerability leverages a classic injection vector, emphasizing the need for secure coding practices such as parameterized queries and input validation. Organizations using yshopmall should assess their exposure and implement compensating controls while awaiting an official fix.

For European organizations, the SQL injection vulnerability in yshopmall poses significant risks to data confidentiality, integrity, and availability. Exploitation could lead to unauthorized data disclosure, including customer information, transaction records, and internal business data, potentially violating GDPR and other data protection regulations. Data manipulation or deletion could disrupt e-commerce operations, leading to financial losses and reputational damage. The remote and unauthenticated nature of the exploit increases the attack surface, allowing attackers to target vulnerable systems over the internet. Organizations relying on yshopmall for online sales or job posting functionalities may experience service interruptions or data breaches. The medium severity score suggests moderate but tangible risk, especially if combined with other vulnerabilities or weak network defenses. The absence of a patch necessitates immediate mitigation to reduce exposure. Additionally, regulatory scrutiny in Europe may increase if breaches occur due to unpatched vulnerabilities, leading to fines and legal consequences.

Given the absence of an official patch, European organizations should implement the following specific mitigations: 1) Apply strict input validation and sanitization on the 'sort' parameter at the application or web server level to block malicious SQL payloads. 2) Employ Web Application Firewalls (WAFs) configured with rules to detect and block SQL injection attempts targeting the /api/jobs endpoint. 3) Restrict database user permissions to the minimum necessary, avoiding use of high-privilege accounts for application connections to limit potential damage. 4) Monitor logs and network traffic for unusual query patterns or repeated access to the vulnerable endpoint. 5) Consider temporarily disabling or restricting access to the /api/jobs API if feasible until a vendor patch is released. 6) Conduct code reviews and penetration testing focused on injection flaws in the application. 7) Stay alert for vendor updates or community patches and apply them promptly. 8) Educate development teams on secure coding practices to prevent similar vulnerabilities in future releases. These targeted actions will help reduce the risk of exploitation while maintaining operational continuity.
