CVE-2025-8541 is a cross-site scripting (XSS) vulnerability identified in version 2.10 of Portabilis i-Educar, an educational management system. The vulnerability resides in the /intranet/public_uf_cad.php file, specifically in the handling of the 'nome' parameter. An attacker can manipulate this parameter to inject malicious scripts that execute in the context of the victim's browser. This type of vulnerability allows remote attackers to perform actions such as stealing session cookies, defacing web content, or redirecting users to malicious sites. The vulnerability does not require authentication but does require user interaction (e.g., the victim must visit a crafted URL). The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:H is unusual but likely a typo or means high privileges required), user interaction required (UI:P), and limited impact on integrity (VI:L) with no impact on confidentiality or availability. The vendor was notified but did not respond, and no patches have been released yet. Although the exploit has been publicly disclosed, there are no known exploits actively used in the wild at this time.

For European organizations using Portabilis i-Educar 2.10, this vulnerability poses a moderate risk primarily to confidentiality and integrity of user sessions and data accessible via the web interface. Educational institutions and administrative bodies relying on i-Educar could face risks of session hijacking, unauthorized actions performed on behalf of users, or exposure of sensitive information through malicious script execution. While the vulnerability does not directly impact system availability, the potential for phishing or social engineering attacks leveraging this XSS flaw could lead to broader security incidents. The lack of vendor response and patch availability increases the window of exposure. European organizations with large user bases or those handling sensitive student data are particularly vulnerable to reputational damage and compliance issues under GDPR if user data is compromised.

1. Implement strict input validation and output encoding on the 'nome' parameter in /intranet/public_uf_cad.php to neutralize malicious scripts. 2. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. 3. Use web application firewalls (WAFs) with rules targeting common XSS attack patterns to detect and block malicious requests. 4. Educate users to avoid clicking on suspicious links and report unusual behavior. 5. Monitor web server logs for unusual parameter values or repeated attempts to exploit this vulnerability. 6. If possible, isolate the affected module or restrict access to trusted users until a patch is available. 7. Engage with Portabilis or community forums to track patch releases or unofficial fixes. 8. Consider upgrading to a newer version if available or applying custom patches to sanitize inputs.
