CVE-2025-11605 is a SQL injection vulnerability identified in version 1.0 of the code-projects Client Details System, specifically in the /admin/update-profile.php script. The vulnerability arises from improper sanitization of the uid parameter, which is used in SQL queries without adequate validation or parameterization. This allows a remote attacker to inject malicious SQL code by manipulating the uid argument, potentially leading to unauthorized access, data leakage, or modification of the underlying database. The attack vector is network accessible (AV:N), requires low attack complexity (AC:L), and does not require authentication (AT:N) or user interaction (UI:N), making it relatively easy to exploit. The vulnerability impacts confidentiality, integrity, and availability at a low level, as indicated by the CVSS 4.0 vector and score of 5.3. No known exploits are currently active in the wild, but a public exploit exists, increasing the likelihood of exploitation. The vulnerability affects only version 1.0 of the product, and no official patches or updates have been linked yet. The lack of authentication requirement and remote exploitability make this a significant risk for organizations using this software, especially in administrative contexts where sensitive client data is managed.

For European organizations, exploitation of this SQL injection vulnerability could lead to unauthorized disclosure of sensitive client information, modification or deletion of critical data, and potential disruption of services relying on the Client Details System. This can result in regulatory non-compliance, especially under GDPR, financial losses, reputational damage, and operational downtime. Organizations in sectors such as finance, healthcare, and government that handle sensitive client data are particularly at risk. The ease of remote exploitation without authentication increases the threat level, as attackers can potentially compromise systems without insider access. Additionally, the availability of a public exploit lowers the barrier for attackers, increasing the likelihood of targeted attacks or automated scanning campaigns against vulnerable installations in Europe.

To mitigate this vulnerability, organizations should first verify if they are running code-projects Client Details System version 1.0 and restrict access to the /admin/update-profile.php endpoint to trusted administrators only, ideally via VPN or IP whitelisting. Implement input validation and parameterized queries or prepared statements to prevent SQL injection in the uid parameter. Deploy Web Application Firewalls (WAFs) with rules targeting SQL injection patterns to detect and block malicious payloads. Monitor database logs and application logs for unusual queries or errors indicative of injection attempts. Until an official patch is released, consider isolating the affected system from external networks or applying virtual patching via security appliances. Regularly update and audit the software environment and educate administrators about the risks of SQL injection. Finally, conduct penetration testing and vulnerability scanning to identify and remediate similar injection flaws proactively.
