CVE-2025-13554 identifies a SQL injection vulnerability in version 1.0 of the Campcodes Supplier Management System, specifically within the /index.php file's Login component. The vulnerability arises from improper sanitization of the txtUsername parameter, which is directly used in SQL queries without adequate validation or parameterization. This allows remote attackers to craft malicious input that alters the intended SQL commands executed by the backend database. Exploitation does not require authentication or user interaction, making it remotely exploitable over the network. Successful exploitation can lead to unauthorized data access, modification, or deletion, potentially compromising the confidentiality, integrity, and availability of the supplier management data. Although the exact function affected is unspecified, the login component is critical for access control, increasing the risk of privilege escalation or bypass. The vulnerability has been publicly disclosed, increasing the risk of exploitation, but no active exploits have been reported yet. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P) indicates network attack vector, low attack complexity, no privileges or user interaction required, and partial impact on confidentiality, integrity, and availability. This vulnerability highlights the need for secure coding practices such as input validation and use of prepared statements in web applications handling sensitive business data.

For European organizations using Campcodes Supplier Management System 1.0, this vulnerability poses significant risks including unauthorized access to sensitive supplier and business data, data tampering, and potential disruption of supplier management operations. Compromise of the login component could allow attackers to bypass authentication or escalate privileges, leading to broader system compromise. The impact extends to confidentiality breaches of supplier contracts, pricing, and personal data, which may violate GDPR and other data protection regulations, resulting in legal and financial penalties. Integrity violations could disrupt supply chain processes, causing operational delays and financial losses. Availability impacts could interrupt supplier communications and order processing. Given the remote exploitability without authentication, attackers can launch automated attacks at scale, increasing the risk for organizations with internet-facing instances of the system. The medium severity rating reflects these risks balanced against the limited scope to version 1.0 and the absence of known active exploits.

Organizations should immediately audit their use of Campcodes Supplier Management System version 1.0 and prioritize upgrading to a patched version once available. In the absence of an official patch, implement the following mitigations: 1) Apply strict input validation and sanitization on the txtUsername parameter to reject malicious SQL syntax. 2) Refactor the login component to use parameterized queries or prepared statements to prevent SQL injection. 3) Restrict network access to the supplier management system, limiting exposure to trusted internal networks or VPNs. 4) Monitor logs for suspicious login attempts or unusual database query patterns indicative of injection attempts. 5) Employ Web Application Firewalls (WAFs) with SQL injection detection rules tailored to the application’s traffic. 6) Conduct regular security assessments and code reviews focusing on input handling. 7) Implement database least privilege principles, ensuring the application account has minimal rights to limit damage from injection. 8) Educate development and operations teams on secure coding and patch management practices. These targeted actions go beyond generic advice by focusing on the specific vulnerable parameter and component.
