How the Exploit Works

This vulnerability stems from improper validation of user-supplied input within the WebDAV protocol. When an attacker crafts a malicious request to a WebDAV server, they can manipulate the file name or path that the server interacts with. This allows the attacker to execute arbitrary code on the server, potentially leading to system compromise or data leakage.

Conceptual Example Code

Consider the following conceptual example of the vulnerability being exploited:

PROPFIND / HTTP/1.1
Host: target.example.com
Depth: 1
Content-Type: text/xml; charset="utf-8"
<?xml version="1.0"?>
<a:propfind xmlns:a="DAV:">
<a:prop>
<a:getcontentlength/>
<a:getlastmodified/>
<a:resourcetype/>
<a:creationdate/>
<a:getetag/>
</a:prop>
</a:propfind>

In this example, the PROPFIND method, which is used to retrieve properties for a resource on a WebDAV server, could be manipulated by an attacker. By exploiting the vulnerability, the attacker could potentially control the paths or filenames that the server interacts with, leading to potential system compromise or data leakage.

Recommended Mitigation Strategies

To mitigate the risks associated with CVE-2025-33053, users are advised to apply the latest vendor-provided patches to their WebDAV servers.
