CVE-2025-7594 is a critical SQL Injection vulnerability identified in version 1.0 of the code-projects Job Diary application. The vulnerability resides in the /view-emp.php file, specifically in the handling of the 'ID' parameter. An attacker can manipulate this parameter to inject malicious SQL code, which the application then executes on the backend database. This flaw allows remote exploitation without requiring authentication or user interaction, making it particularly dangerous. The injection can lead to unauthorized data access, data modification, or even full compromise of the underlying database server. Although the CVSS 4.0 score is 6.9 (medium severity), the nature of SQL injection vulnerabilities typically warrants careful attention due to their potential to impact confidentiality, integrity, and availability of data. The vulnerability is exploitable over the network, with low attack complexity and no privileges or user interaction needed. No official patch or mitigation has been published yet, and while no known exploits are currently reported in the wild, the public disclosure increases the risk of exploitation by threat actors.

For European organizations using code-projects Job Diary 1.0, this vulnerability poses a significant risk to sensitive employee and operational data. Exploitation could lead to unauthorized disclosure of confidential information, including personal employee records, which would have serious compliance implications under GDPR. Data integrity could be compromised, affecting business operations and decision-making. Additionally, attackers could leverage this vulnerability to pivot within the network, potentially escalating to broader system compromise. The remote and unauthenticated nature of the exploit increases the likelihood of attacks, especially against organizations with internet-facing deployments of the affected software. The absence of a patch means organizations must rely on alternative mitigations to reduce exposure. The reputational damage and potential regulatory penalties from data breaches resulting from this vulnerability could be substantial for European companies.

Given the lack of an official patch, European organizations should immediately implement strict input validation and parameterized queries or prepared statements in the /view-emp.php script to prevent SQL injection. If source code modification is not feasible, deploying a Web Application Firewall (WAF) with custom rules to detect and block malicious SQL payloads targeting the 'ID' parameter is critical. Network segmentation should be enforced to limit access to the Job Diary application backend databases. Organizations should also conduct thorough code audits to identify similar injection points. Monitoring and logging of database queries and web application traffic should be enhanced to detect suspicious activity early. Finally, organizations should plan for rapid patch deployment once an official fix is released and consider temporary removal or replacement of the vulnerable application if risk tolerance is low.
