Detection Guidance

This vulnerability can be detected by checking for the presence of the vulnerable endpoint `/intranet/educar_turma_tipo_cad.php` in your Portabilis i-Educar installation. You can use Google dorking with queries like `inurl:intranet/educar_turma_tipo_cad.php` to identify potentially vulnerable targets. Additionally, you can test the vulnerability by attempting to inject a known XSS payload into the `nm_tipo` parameter, such as `"><img src=x onerror=alert('CVE-Hunters')>`, and then observe if the payload executes when accessing the related page `/intranet/educar_turma_tipo_lst.php`. For local testing, you might use curl or similar tools to send crafted requests to the vulnerable endpoint and check the response or behavior. [1, 2]

Mitigation Strategies

No known mitigations or countermeasures have been published for this vulnerability. The suggested immediate step is to replace the affected component or upgrade to a version of Portabilis i-Educar that is not vulnerable, if available. Additionally, as a temporary measure, you could restrict access to the vulnerable endpoint `/intranet/educar_turma_tipo_cad.php` or implement web application firewall (WAF) rules to block malicious input targeting the `nm_tipo` parameter. Monitoring and alerting on suspicious activity related to this endpoint is also recommended. [1]
