The vulnerability identified as CVE-2025-69562 affects the code-projects Mobile Shop Management System version 1.0. It is a classic SQL Injection (CWE-89) vulnerability located in the /insertmessage.php endpoint, specifically through the userid parameter. SQL Injection occurs when user-supplied input is improperly sanitized and directly concatenated into SQL queries, allowing attackers to manipulate the database queries executed by the application. In this case, the userid parameter is not properly validated or escaped, enabling an attacker to inject malicious SQL code remotely without any authentication or user interaction. The CVSS 3.1 base score of 9.8 indicates a critical severity, with attack vector being network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), and high impacts on confidentiality (C:H), integrity (I:H), and availability (A:H). This means an attacker can fully compromise the backend database, potentially extracting sensitive customer data, modifying or deleting records, or even executing administrative commands if the database user has elevated privileges. Although no public exploits have been reported yet, the vulnerability’s nature and severity make it a prime target for attackers once exploit code becomes available. The lack of available patches or updates increases the urgency for organizations to implement interim mitigations. The vulnerability affects all deployments of the Mobile Shop Management System 1.0 that expose the vulnerable endpoint and do not have compensating controls in place.

For European organizations, especially those operating retail or mobile shop management systems using this vulnerable software, the impact could be severe. Confidential customer data, including personal and transactional information, could be stolen, leading to privacy violations and regulatory penalties under GDPR. Integrity of business data could be compromised, resulting in fraudulent transactions, inventory manipulation, or financial losses. Availability could also be affected if attackers delete or corrupt critical data, disrupting business operations. The reputational damage from a breach could be significant, affecting customer trust and market position. Given the critical severity and ease of exploitation, attackers could rapidly weaponize this vulnerability to target multiple organizations. The lack of patches means organizations must rely on immediate mitigations to reduce risk. The threat is particularly relevant to European countries with a strong retail sector or where this software has market penetration, as well as those with stringent data protection regulations that increase the cost of breaches.

1. Immediate code review and remediation: Developers should implement parameterized queries or prepared statements for all database interactions involving user input, especially the userid parameter in /insertmessage.php. 2. Input validation: Enforce strict input validation and sanitization on all user-supplied data to reject malicious payloads. 3. Web application firewall (WAF): Deploy and configure a WAF with rules to detect and block SQL Injection attempts targeting the vulnerable endpoint. 4. Network segmentation: Isolate the vulnerable application and its database from critical internal networks to limit lateral movement in case of compromise. 5. Monitoring and logging: Enable detailed logging of database queries and web requests to detect suspicious activity and facilitate incident response. 6. Access controls: Restrict database user privileges to the minimum necessary to reduce the impact of a successful injection. 7. Patch management: Monitor for official patches or updates from the vendor and apply them promptly once available. 8. Incident response planning: Prepare for potential exploitation scenarios with defined response procedures to minimize damage. 9. Vendor engagement: Contact the software vendor for guidance, timelines for patches, and possible workarounds. 10. Alternative solutions: Evaluate replacing the vulnerable system with more secure alternatives if remediation is delayed.
