How the Exploit Works
The exploit takes advantage of an XSS vulnerability in the PdfViewer component of Agenzia Impresa Eccobook. An attacker can inject a crafted payload into the Temp parameter, which is subsequently executed when a user interacts with the PdfViewer. This allows the attacker to execute arbitrary web scripts or HTML, potentially compromising the system or causing data leakage.
Conceptual Example Code
The following is a conceptual example of how the vulnerability might be exploited. This is a malicious HTTP request, where the payload is injected into the Temp parameter.
POST /pdfviewer?temp= HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
temp=<script>malicious_script</script>The “malicious_script” would be replaced with the actual malicious script that the attacker wants to execute.
Mitigation Guidance
The recommended mitigation is to apply the vendor patch as soon as it becomes available. In the interim, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. These systems can be configured to block or alert on attempts to exploit this vulnerability. However, they should not be considered a long-term solution, as they cannot guarantee complete protection against this threat.
