CVE-2025-11109 identifies a SQL injection vulnerability in Campcodes Computer Sales and Inventory System version 1.0, specifically in the /pages/us_edit.php?action=edit script. The vulnerability arises from improper sanitization of the ID parameter, which is directly used in SQL queries. This allows remote attackers to craft malicious input that alters the intended SQL command, potentially extracting sensitive information, modifying data, or disrupting database operations. The attack vector requires no authentication or user interaction, making it accessible to any remote adversary with network access to the application. The CVSS 4.0 score of 6.9 reflects a medium severity, considering the lack of authentication but limited scope and impact compared to more critical injection flaws. No patches have been officially released yet, and while no active exploitation has been reported, a public exploit exists, increasing the likelihood of future attacks. The vulnerability affects only version 1.0 of the product, which is used primarily for managing sales and inventory data, making confidentiality and integrity of business-critical data the main concerns. The vulnerability does not require special privileges or social engineering, which increases its risk profile. The absence of supply chain or third-party dependencies limits the attack surface to direct exploitation of the vulnerable endpoint.

For European organizations using Campcodes Computer Sales and Inventory System 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of sensitive sales and inventory data. Exploitation could lead to unauthorized disclosure of customer information, pricing, stock levels, and transactional records, potentially resulting in financial loss, reputational damage, and regulatory non-compliance (e.g., GDPR violations). Data manipulation could disrupt inventory management, causing operational inefficiencies or stock inaccuracies. The availability impact is limited but possible if attackers execute destructive SQL commands. Since the vulnerability requires no authentication, attackers can exploit it remotely, increasing exposure. Organizations in retail, wholesale, and distribution sectors relying on this system are particularly vulnerable. The presence of a public exploit increases the likelihood of opportunistic attacks, especially from cybercriminals targeting smaller enterprises with limited cybersecurity resources.

1. Immediately implement input validation and sanitization on the ID parameter in /pages/us_edit.php to prevent injection of malicious SQL code. 2. Refactor database queries to use parameterized statements or prepared queries, eliminating direct concatenation of user input. 3. Monitor database logs and application logs for unusual query patterns or repeated failed attempts targeting the vulnerable endpoint. 4. Restrict network access to the application server using firewalls or VPNs to limit exposure to trusted users only. 5. Conduct a thorough audit of all input handling in the application to identify and remediate similar injection risks. 6. If possible, upgrade to a patched version once released by the vendor or apply vendor-provided patches promptly. 7. Employ Web Application Firewalls (WAF) with SQL injection detection rules to provide an additional layer of defense. 8. Educate IT and security teams about the vulnerability and ensure incident response plans include steps for SQL injection incidents. 9. Regularly back up critical data and verify backup integrity to enable recovery in case of data tampering or loss.
