Overview
We are addressing a critical vulnerability identified as CVE-2025-55147, which affects multiple products from Ivanti, a software company that develops IT management and security solutions. This vulnerability allows a remote unauthenticated attacker to execute sensitive actions on behalf of a victim user, creating grave security concerns for organizations worldwide.
The vulnerability in question is a Cross-Site Request Forgery (CSRF) that is present in several Ivanti products. The impact of this vulnerability is significant as it could potentially lead to system compromise or data leakage. As such, it is crucial to understand the details of this vulnerability, how it operates, and how to mitigate its risks.

How the Exploit Works
The vulnerability works through a CSRF attack where an attacker tricks a victim into executing unintended actions on a web application in which they’re authenticated. In this case, a remote unauthenticated attacker can execute sensitive actions on behalf of the victim user. The attacker exploits the trust that a site has in a user’s browser by causing the victim to send an HTTP request to a target site, thereby carrying out an action on behalf of the victim.
Conceptual Example Code
Below is a conceptual example of how the vulnerability might be exploited. It illustrates a simplified CSRF attack where an attacker constructs a malicious payload embedded in a seemingly harmless URL or webpage:
POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"user_action": "change_password",
"new_password": "attacker_password"
}Once the victim interacts with this URL or webpage, the malicious request is sent to the server and the action (in this case, changing the password) is performed on behalf of the victim, unbeknownst to them.
How to Mitigate
To mitigate this vulnerability, organizations should apply the vendor patch as soon as possible. If immediate patching isn’t feasible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation, but they should not be seen as a long-term solution. Always ensure your systems are updated with the latest patches to ensure the best defense against potential cybersecurity threats.
