# WeGIA: stored script injection in memorandum threads hijacks sessions

WeGIA, a web manager for charitable institutions, stores memorandum dispatch text that is later decoded and inserted into the page without escaping. A user who can submit a dispatch can run JavaScript in the browser of anyone who views that memorandum thread, including administrators, and steal their session tokens.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed WeGIA version and whether it is below `3.8.7`.
- Look for the file `web/html/memorando/listar_despachos.php` in the WeGIA install.
- Confirm whether the memorandum module is in use by staff accounts.

## Fix

- Upgrade WeGIA to `3.8.7` or later.

## From the sources

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.
