How the Exploit Works
The vulnerability stems from the improper restriction of XML External Entity (XXE) reference within Dell Storage Manager. In essence, the software fails to properly sanitize user-supplied input, allowing an attacker to inject malicious XML directly into the application.
This can lead to two primary exploitations. Firstly, an attacker can use this vulnerability to probe internal networks, access local files, or even interact with other internal systems. Secondly, the attacker can modify data processed by the application, leading to information tampering.
Conceptual Example Code
A potential exploitation of this vulnerability could look something like the following HTTP POST request:
POST /DellStorageManager/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/xml
<!DOCTYPE foo [
<!ELEMENT foo ANY >
<!ENTITY xxe SYSTEM "file:///etc/passwd" >]>
<foo>&xxe;</foo>In this example, the attacker sends a malicious XML document containing an external entity declaration. The SYSTEM keyword is used to specify an URI (in this case, a local file). When processed by the vulnerable application, it would attempt to replace “&xxe;” with the content of the file at the specified URI, leading to potential information disclosure.

Countermeasures
The recommended countermeasure for this vulnerability is to apply the vendor-supplied patch. If the patch cannot be applied immediately, the use of a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) is advised as a temporary mitigation measure. These solutions can help detect and block XXE attacks.
Conclusion
CVE-2025-22478 represents a significant threat to organizations using Dell Storage Manager. It’s crucial to address this vulnerability promptly to protect sensitive information and maintain the integrity of your systems. Always stay informed about the latest vulnerabilities and ensure your systems are up-to-date with the latest patches and updates.
