Can you explain this vulnerability to me?
CVE-2025-8788 is a Stored Cross-Site Scripting (XSS) vulnerability in Portabilis i-Diario up to version 1.5.0. It affects the endpoint `/planos-de-aula-por-areas-de-conhecimento/` where user inputs in the parameters `Parecer`, `Conteúdos`, and `Objetivos` are not properly validated or sanitized. Attackers can inject malicious JavaScript code via these parameters, which is then stored on the server and executed in the browsers of users who visit the affected page. This allows attackers to perform actions such as stealing session cookies, hijacking user sessions, delivering malware, and altering website content. [1, 2]
How can this vulnerability impact me? :
This vulnerability can lead to several security impacts including theft of session cookies enabling session hijacking, installation of malware on victim machines, browser hijacking, theft of user credentials, unauthorized access to sensitive user information, website defacement, misdirection of users by altering website instructions, and damage to business reputation through misinformation or defacement. [1]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by testing the affected endpoint `/planos-de-aula-por-areas-de-conhecimento/[ID]` for stored cross-site scripting (XSS) by injecting typical XSS payloads into the parameters `Parecer`, `Conteúdos`, and `Objetivos`. For example, sending a POST request with a payload like `<script>alert('PoC-XXS2')</script>` in the `Parecer` parameter and then checking if the script executes when accessing the affected page or the "Histórico" option. Detection commands could include using curl or similar tools to send crafted POST requests, such as: `curl -X POST -d "Parecer=<script>alert('PoC-XXS2')</script>" https://target/planos-de-aula-por-areas-de-conhecimento/[ID]`. Afterwards, manually or automatically verify if the payload executes in the browser when visiting the page. Monitoring web application logs for suspicious input patterns in these parameters may also help detect exploitation attempts. [1, 2]
What immediate steps should I take to mitigate this vulnerability?
There are no known patches or vendor-provided mitigations for this vulnerability as the vendor did not respond to the disclosure. Immediate mitigation steps include: avoiding use of the affected product version (Portabilis i-Diario up to 1.5.0), restricting access to the vulnerable endpoint if possible, implementing web application firewall (WAF) rules to detect and block typical XSS payloads targeting the parameters `Parecer`, `Conteúdos`, and `Objetivos`, and educating users to be cautious of unexpected content on the affected pages. Consider replacing the affected product with a secure alternative until a fix is available. [2]
