CVE-2025-15011 identifies a SQL injection vulnerability in the Simple Stock System version 1.0 developed by code-projects. The vulnerability resides in the /logout.php script, specifically in the handling of the uname parameter. Due to insufficient input validation or sanitization, attackers can inject crafted SQL statements remotely without authentication or user interaction. This injection can manipulate backend SQL queries, potentially allowing attackers to read, modify, or delete database records, thereby compromising data confidentiality, integrity, and availability. The CVSS 4.0 base score is 6.9 (medium), reflecting network attack vector, low complexity, no privileges or user interaction required, and partial impact on confidentiality, integrity, and availability. Although no exploits have been observed in the wild, the public disclosure of exploit code increases the likelihood of exploitation attempts. The vulnerability affects only version 1.0 of the product, and no official patches or updates have been published at the time of disclosure. The lack of patch availability necessitates immediate mitigation through secure coding practices, input validation, and database access restrictions. This vulnerability highlights the importance of sanitizing all user inputs, especially in web applications handling critical business functions such as stock management.

The SQL injection vulnerability allows remote attackers to execute arbitrary SQL commands on the backend database without authentication, potentially leading to unauthorized data access, data corruption, or deletion. This can result in leakage of sensitive business information, manipulation of stock records, or denial of service if critical database tables are altered or dropped. For organizations relying on the Simple Stock System for inventory management, this could disrupt operations, cause financial losses, and damage reputation. The medium severity rating reflects that while the impact is significant, it is not fully critical since the scope of impact is limited to the database and requires exploitation of a specific parameter. However, the ease of remote exploitation without credentials increases the risk profile. Organizations with inadequate network segmentation or monitoring may be more vulnerable to automated or targeted attacks leveraging this flaw. The absence of known exploits in the wild currently limits immediate widespread impact, but the public availability of exploit code could lead to rapid exploitation in the near term.

Since no official patches are currently available, organizations should implement immediate mitigations including: 1) Applying strict input validation and sanitization on the uname parameter in /logout.php to neutralize SQL metacharacters and prevent injection. 2) Employing parameterized queries or prepared statements in the application code to separate SQL logic from user input. 3) Restricting database user permissions to the minimum necessary, preventing the application from performing destructive operations. 4) Monitoring web application logs and database logs for suspicious queries or unusual activity related to the uname parameter. 5) Implementing web application firewalls (WAF) with rules to detect and block SQL injection attempts targeting this endpoint. 6) Considering network segmentation to limit exposure of the vulnerable system to untrusted networks. 7) Planning and testing an upgrade or patch deployment once the vendor releases an official fix. 8) Educating development teams on secure coding practices to prevent similar vulnerabilities in future releases.
