CVE-2025-11425 identifies a cross-site scripting vulnerability in version 1.0 of the projectworlds Advanced Library Management System, specifically within the /edit_admin.php script. The vulnerability arises from improper sanitization of the 'firstname' parameter, which allows remote attackers to inject malicious JavaScript code. The attack vector is network-based with low attack complexity, requiring no authentication but some user interaction, and the vulnerability does not compromise confidentiality or availability directly but impacts integrity to a limited extent. The vulnerability could be exploited by tricking an administrative user into clicking a crafted link or submitting malicious input, leading to script execution in their browser context. This could result in session hijacking, privilege escalation, or unauthorized administrative actions. Although no known exploits are currently observed in the wild, the availability of exploit code increases the risk of exploitation. The vulnerability may also affect other parameters, indicating a broader input validation issue within the application. The CVSS 4.8 score reflects a medium severity, considering the limited scope and required user interaction. The lack of patches at the time of publication necessitates immediate attention to input validation and monitoring.

For European organizations, particularly educational institutions, libraries, and research centers using the projectworlds Advanced Library Management System, this vulnerability poses a risk of unauthorized script execution in administrative sessions. This can lead to session hijacking, unauthorized data manipulation, or changes to system configurations, potentially disrupting library operations and compromising sensitive user data. Although the vulnerability does not directly affect system availability or confidentiality at a large scale, the integrity of administrative functions is at risk. The exploitation could facilitate further attacks within the network if administrative credentials or sessions are compromised. Given the widespread use of library management systems in Europe’s academic and public sectors, the impact could be significant in environments where patching is delayed or where security awareness is low. The medium severity indicates that while the threat is not critical, it could serve as an entry point for more severe attacks if combined with other vulnerabilities or poor security practices.

Organizations should immediately audit their use of projectworlds Advanced Library Management System version 1.0 and restrict access to the /edit_admin.php functionality to trusted administrators only. Implement strict input validation and sanitization on all user-supplied parameters, especially 'firstname' and other potentially vulnerable inputs. Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. Monitor administrative accounts for unusual activity and enforce multi-factor authentication to reduce the risk of session hijacking. Network segmentation should be applied to limit access to the library management system from untrusted networks. Since no official patch is currently available, consider temporary compensating controls such as web application firewalls (WAF) with custom rules to detect and block XSS payloads targeting the vulnerable parameter. Regularly check for vendor updates or security advisories and apply patches promptly once released. Conduct security awareness training for administrators to recognize phishing or social engineering attempts that could trigger exploitation.
