CVE-2025-11582 is a SQL injection vulnerability identified in version 1.0 of the code-projects Online Job Search Engine, specifically in the /registration.php endpoint. The vulnerability arises from improper sanitization or validation of the txtusername parameter, which is susceptible to SQL injection attacks. An attacker can remotely send crafted input to this parameter to manipulate backend SQL queries, potentially extracting sensitive information, modifying database contents, or bypassing authentication mechanisms. The vulnerability requires no authentication or user interaction and can be exploited over the network, increasing its risk profile. 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. Although no known exploits are currently active in the wild, the public availability of exploit code increases the likelihood of exploitation attempts. The lack of available patches or vendor advisories necessitates immediate attention from users of this software. The vulnerability could allow attackers to access or alter user registration data, potentially compromising user privacy and the integrity of the recruitment platform.

For European organizations using the code-projects Online Job Search Engine 1.0, this vulnerability poses a risk of unauthorized access to sensitive user data such as personal information submitted during registration. Attackers could manipulate database queries to extract confidential data, alter user records, or disrupt service availability. This could lead to data breaches, reputational damage, and regulatory non-compliance under GDPR. The impact is particularly significant for recruitment agencies, job boards, and HR departments relying on this platform for candidate management. The medium severity rating reflects partial impact on confidentiality, integrity, and availability, but the ease of exploitation and remote attack vector increase the threat level. Organizations may face targeted attacks aiming to harvest personal data or sabotage recruitment operations. Additionally, compromised systems could be used as pivot points for further network intrusion.

Since no official patches are currently available, European organizations should implement immediate compensating controls. These include applying strict input validation and sanitization on the txtusername parameter, ideally using parameterized queries or prepared statements to prevent SQL injection. Web application firewalls (WAFs) should be configured to detect and block SQL injection payloads targeting /registration.php. Conduct thorough code reviews and penetration testing focused on input handling in the registration module. Monitor logs for unusual database query patterns or repeated failed registration attempts indicative of exploitation attempts. Limit database user privileges to the minimum necessary to reduce potential damage. If possible, isolate the vulnerable application from critical internal networks. Organizations should also engage with the vendor for updates and consider migrating to alternative platforms if remediation is delayed. Regular backups and incident response plans should be updated to address potential exploitation scenarios.
