The CVE-2025-40456 vulnerability in Mangati NovoSGA stems from inadequate input sanitization within the SVG file handler component, specifically in the `/admin` endpoint. The parameters `logoNavbar` and `logoLogin` are susceptible to reflected Cross-Site Scripting (XSS) attacks. When these parameters receive malicious input containing JavaScript code, the application fails to properly encode or validate the data before incorporating it into the generated web page. Consequently, an attacker can craft a specialized URL containing a malicious script payload. If an authenticated administrator clicks this link, the embedded script executes within their browser session in the context of the vulnerable admin panel. This allows the attacker to steal the administrator’s session cookies, perform actions on their behalf, or deface the admin interface. The vulnerability is remotely exploitable and a public exploit exists.
Platform: Mangati NovoSGA
Version: up to 2.2.9
Vulnerability: XSS
Severity: Low
date: 2024-09-24
Prediction: 2024-10-15
What Undercode Say:
curl -s "http://target.com/admin" -G --data-urlencode "logoNavbar=<script>alert('XSS')</script>"
<!-- Proof-of-Concept --> <img src=x onerror=stealCookie()>
How Exploit:
An attacker crafts a malicious URL targeting the `/admin` endpoint with a JavaScript payload in the `logoNavbar` or `logoLogin` parameter. This URL is then delivered to an administrator via phishing email or a malicious link. Upon visiting the link, the XSS payload executes.
Protection from this CVE:
Apply vendor patch.
Implement strict input sanitization.
Use Content Security Policy (CSP).
Impact:
Session hijacking.
Unauthorized admin actions.
UI defacement.
