Summary

WeGIA, a web manager for charitable institutions, is affected before 3.8.7. A stored DOM cross-site scripting flaw (CWE-79) in listar_despachos.php occurs because content saved with FILTER_SANITIZE_SPECIAL_CHARS is later decoded with html_entity_decode() and inserted into the page with jQuery .html(). An attacker who can submit a memorandum dispatch can store malicious HTML or JavaScript that runs automatically when another user views the memorandum thread. This can lead to theft of administrator PHPSESSID session tokens and account takeover, and CISA does not list it in KEV.

Description from the CNA

WeGIA is a web manager for charitable institutions. Prior to 3.8.7, a stored DOM cross-site scripting vulnerability in `web/html/memorando/listar_despachos.php` results from unsafe handling of the `texto` field. The affected flow spans `web/controle/memorando/DespachoControle.php` and `web/dao/memorando/DespachoDAO.php`: `FILTER_SANITIZE_SPECIAL_CHARS` is applied during storage, but `html_entity_decode()` later decodes the stored content and `jQuery .html()` inserts the result into the DOM. An attacker able to submit a memorandum dispatch through `/controle/control.php` using `DespachoControle` and `metodo=incluir` can store malicious HTML or JavaScript. The code executes automatically when another user views the memorandum thread through `/html/memorando/listar_despachos.php` with `id_memorando`. This permits arbitrary JavaScript execution, theft of administrator `PHPSESSID` session tokens, privileged session hijacking, account takeover, and unauthorized access to privileged or internal functionality. This issue is fixed in version 3.8.7.
