CVE-2025-11583 identifies a SQL injection vulnerability in the code-projects Online Job Search Engine version 1.0, specifically within the /postjob.php script. The vulnerability arises from improper handling of the txtjobID parameter, which is susceptible to direct manipulation by remote attackers without any authentication or user interaction. This allows attackers to inject malicious SQL code into backend database queries, potentially enabling unauthorized access to sensitive data, data modification, or even deletion. The vulnerability is exploitable over the network (AV:N) with low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The impact on confidentiality, integrity, and availability is low individually but combined can lead to significant data exposure or service disruption. The exploit has been publicly disclosed, increasing the risk of exploitation despite no known active attacks. The lack of patches or vendor-provided fixes necessitates immediate mitigation by users. The vulnerability affects only version 1.0 of the product, which may limit exposure but still poses a risk to organizations relying on this software for job posting and search functionalities. The CVSS vector indicates partial impact on confidentiality, integrity, and availability, emphasizing the need for input validation and secure coding practices to prevent exploitation.

For European organizations using the code-projects Online Job Search Engine 1.0, this vulnerability could lead to unauthorized disclosure of sensitive job posting data, candidate information, or internal business data stored in the backend database. Attackers could manipulate or delete data, undermining the integrity and availability of the job search platform. This could result in reputational damage, regulatory non-compliance (especially under GDPR if personal data is exposed), and operational disruptions. The remote and unauthenticated nature of the exploit increases the risk of widespread attacks, particularly targeting recruitment agencies, HR departments, and job boards that rely on this software. The medium severity rating suggests moderate but actionable risk, with potential for escalation if combined with other vulnerabilities or misconfigurations. The lack of known active exploits provides a window for proactive defense but also means organizations should not delay remediation. The impact on availability could disrupt recruitment processes, affecting business continuity and talent acquisition efforts.

European organizations should immediately audit their use of the code-projects Online Job Search Engine to identify any deployments of version 1.0. Since no official patch is currently available, organizations must implement input validation and sanitization on the txtjobID parameter, preferably by refactoring the code to use prepared statements or parameterized queries to prevent SQL injection. Employing Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting /postjob.php can provide interim protection. Regularly monitoring logs for suspicious query patterns or repeated access attempts to the vulnerable endpoint is critical. Organizations should also consider isolating the affected application from sensitive backend systems and databases to limit potential damage. Conducting penetration testing focused on injection flaws can help verify the effectiveness of mitigations. Finally, organizations should engage with the vendor or community for updates and patches and plan for an upgrade or replacement of the vulnerable software version.
