Executive Summary

CVE-2025-9653 is a Stored Cross-Site Scripting (XSS) vulnerability in the Portabilis i-Educar application up to version 2.10. It occurs in the /intranet/educar_projeto_cad.php file, specifically in the 'Cadastrar projeto' page, where the 'nome' and 'observacao' input parameters are not properly validated or sanitized. Attackers can inject malicious scripts into these fields, which are then stored on the server. When other users visit the related page (/intranet/educar_projeto_lst.php), the malicious scripts execute in their browsers, potentially leading to various attacks. [1, 2]

Impact Analysis

This vulnerability can lead to session cookie theft, browser hijacking, credential theft, malware distribution, unauthorized access to sensitive information, website defacement, user misdirection, and reputational damage to affected organizations. Since the malicious scripts execute in users' browsers, attackers can manipulate user sessions and data, potentially compromising user accounts and the integrity of the affected system. [1]

Detection Guidance

This vulnerability can be detected by testing the /intranet/educar_projeto_cad.php endpoint for improper input sanitization in the 'nome' and 'observacao' parameters. One approach is to submit a payload such as `"><img src=x onerror=alert('CVE-Hunters')>` into these fields and then check if the script executes when accessing /intranet/educar_projeto_lst.php. Additionally, attackers may use Google dorking with queries like `inurl:intranet/educar_projeto_cad.php` to identify vulnerable targets. There are no specific network commands provided, but manual or automated web application testing tools can be used to inject and detect stored XSS payloads. [1, 2]

Mitigation Strategies

No known countermeasures or mitigations have been published for this vulnerability. It is suggested to consider replacing the affected product with an alternative. Immediate steps include restricting access to the vulnerable endpoint, applying input validation and sanitization if possible, and monitoring for suspicious activity. Since the exploit is publicly available and the vulnerability is remotely exploitable, limiting user privileges and applying web application firewall (WAF) rules to detect and block XSS payloads may help mitigate risk until a patch or replacement is implemented.
