DescriptionCVE.org

A vulnerability was found in Portabilis i-Educar 2.9.0. It has been rated as problematic. This issue affects some unknown processing of the file /intranet/educar_deficiencia_lst.php of the component Disabilities Module. The manipulation of the argument Deficiência ou Transtorno leads to cross site scripting. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

AnalysisAI

Stored cross-site scripting (XSS) in Portabilis i-Educar 2.9.0 allows authenticated users to inject malicious scripts via the 'Deficiência ou Transtorno' parameter in the Disabilities Module (/intranet/educar_deficiencia_lst.php), affecting other users who view the injected content. The vulnerability requires user interaction (victim must view the page) and authenticated access, limiting its severity to reflected/stored XSS with user-level privileges. Public exploit code exists, but active exploitation has not been confirmed in CISA KEV, and the vendor has not responded to disclosure.

Technical ContextAI

The vulnerability resides in the Disabilities Module component of i-Educar, a Brazilian education management platform built on PHP. The flaw is a classic CWE-79 (Improper Neutralization of Input During Web Page Generation) in the /intranet/educar_deficiencia_lst.php file, where user-supplied input via the 'Deficiência ou Transtorno' (Disability or Disorder) parameter is not sanitized or HTML-encoded before being rendered in the web response. This allows attackers to embed arbitrary JavaScript that executes in the context of other users' browsers when they interact with the affected page. The attack surface is limited to authenticated users with access to the Disabilities Module, reducing the exposure compared to unauthenticated XSS.

RemediationAI

No vendor-released patch has been identified at the time of analysis; Portabilis did not respond to disclosure. Immediate workarounds include: (1) Apply input validation and output encoding to the 'Deficiência ou Transtorno' parameter in /intranet/educar_deficiencia_lst.php - use htmlspecialchars() or equivalent context-aware encoding before rendering to HTML; (2) Restrict access to the Disabilities Module to trusted administrators only via role-based access control, reducing the attack surface; (3) Implement a Web Application Firewall (WAF) rule to block or sanitize script tags in the affected parameter; (4) Monitor the Portabilis GitHub repository or community forums for unofficial patches or new releases that may address this issue. Organizations using i-Educar should contact Portabilis directly to report the vulnerability and request a patched version. Until a patch is available, the encoding fix is the most reliable short-term mitigation, with a trade-off of minimal performance impact.
