Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: Reflected XSS in WeGIA. ๐ **Consequences**: Attackers inject malicious scripts via the `id_memorando` GET parameter. Victims execute code in their browser, leading to session hijacking or data theft.
Q2Root Cause? (CWE/Flaw)
๐ก๏ธ **Root Cause**: CWE-79 (Improper Neutralization of Input). ๐ **Flaw**: The file `html/memorando/insere_despacho.php` fails to sanitize/encode user input from the `id_memorando` parameter before rendering it in HTML.
๐ป **Privileges**: No authentication required (PR:N). ๐ต๏ธ **Data**: High impact on Confidentiality & Integrity (C:H, I:H). Hackers can steal cookies, redirect users, or deface pages via reflected script execution.
Q5Is exploitation threshold high? (Auth/Config)
๐ **Threshold**: LOW. ๐ **Config**: Network Accessible (AV:N). No Privileges Required (PR:N). No User Interaction Required (UI:N). It is a trivial, remote exploit.
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ **Public Exp**: No specific PoC code provided in data. ๐ **Status**: Advisory confirmed via GitHub Security Advisory (GHSA-g7hh-6qj7-mcqf). Exploitation logic is straightforward given the reflection nature.
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: Scan for `id_memorando` parameter in `insere_despacho.php`. ๐งช **Test**: Inject `<script>alert(1)</script>` into the GET request. If reflected/executed, the system is vulnerable.
Q8Is it fixed officially? (Patch/Mitigation)
๐ง **Fix**: Upgrade to **WeGIA version 3.6.2** or later. ๐ฅ **Source**: Official GitHub repository advisory confirms the patch exists in the newer release.
Q9What if no patch? (Workaround)
๐ง **Workaround**: If patching is delayed, implement strict input validation on the server side. ๐ก๏ธ **Mitigation**: Encode all output related to `id_memorando` using HTML entity encoding before rendering.
Q10Is it urgent? (Priority Suggestion)
๐ฅ **Urgency**: HIGH. ๐จ **Priority**: CVSS 3.1 Score indicates Critical impact (C:H, I:H). Immediate patching is recommended due to zero-auth requirement and high severity.
