How the Exploit Works
The exploit leverages a flaw in the 3DAlloy’s 3D viewer for MediaWiki. Specifically, the `<3d>` parser tag and the `{{#3d}}` parser function allow users to provide custom attributes, which are then appended to the HTML canvas element output by the extension. The issue arises because these attributes are not sanitized, potentially allowing an attacker to inject malicious JavaScript code. When this malicious code is executed, it can lead to severe consequences such as system compromise or data leakage.
Conceptual Example Code
Here is a conceptual example illustrating how the vulnerability might be exploited. In this case, the attacker sends a request with malicious JavaScript code as a custom attribute:
<3d custom_attribute="javascript:malicious_code()">In this example, `malicious_code()` represents the attacker’s arbitrary JavaScript code. When the server processes this request, the malicious JavaScript code is executed, potentially leading to system compromise or data leakage.
Mitigation Guidance
It is advised to apply the vendor patch as soon as it is available. In the meantime, using a web application firewall (WAF) or an intrusion detection system (IDS) could serve as temporary mitigation. These tools can help detect and block malicious requests, providing a layer of protection against potential exploitation of this vulnerability.
