Can you explain this vulnerability to me?
CVE-2025-8540 is a stored Cross-Site Scripting (XSS) vulnerability in Portabilis i-Educar version 2.10, specifically in the file /intranet/public_municipio_cad.php. It occurs due to improper validation and sanitization of the 'nome' parameter, allowing an attacker to inject malicious scripts that are stored on the server. When other users access the affected page, these scripts execute in their browsers, potentially leading to various malicious outcomes. [1, 2]
How can this vulnerability impact me? :
This vulnerability can lead to session cookie theft, browser hijacking, credential theft, malware delivery, unauthorized access to sensitive information, website defacement, user misdirection, and reputational damage to the affected organization. It allows attackers to execute malicious scripts in the context of other users, potentially compromising their data and security. [1, 2]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by checking if the affected endpoint `/intranet/public_municipio_cad.php` is present and vulnerable to stored XSS via the `nome` parameter. One method is to attempt injecting a harmless payload such as `<img src=x onerror=alert(1)>` into the "Nome" field after selecting "Brasil" in the "País" field and any option in the "Estado" field, then saving the input. Subsequently, accessing `/intranet/public_municipio_lst.php` should reveal if the payload executes, indicating vulnerability. Additionally, vulnerable targets can be identified using Google dorking with the query `inurl:intranet/public_municipio_cad.php` to find instances of the affected application. [1, 2]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include avoiding use of the affected Portabilis i-Educar version 2.10 or replacing it with a non-vulnerable version or alternative product, as no official patches or vendor responses are available. Restricting access to the affected endpoints to trusted users only and implementing web application firewalls (WAF) to filter malicious input targeting the `nome` parameter may help reduce risk. Monitoring and alerting on suspicious input patterns and user activities related to this endpoint is also recommended. [2]
