CVE-2025-36202: Command Execution Vulnerability in IBM webMethods Integration

Views: 18

Overview

The CVE-2025-36202 vulnerability is a significant flaw in IBM’s webMethods Integration versions 10.15 and 11.1. This vulnerability, if exploited, could allow authenticated users with specific service execution privileges to carry out commands on the system. This flaw arises from improper validation of format string strings passed from an external source. It presents a substantial threat to organizational cybersecurity, potentially leading to system compromise or data leakage.

How the Exploit Works

The vulnerability is rooted in the improper validation of format string strings. An attacker, authenticated and possessing the necessary service execution privileges, could exploit this flaw to pass malicious commands from an external source. The system, failing to validate these strings adequately, could execute these commands, potentially compromising the system or leading to data leakage.

Conceptual Example Code

Here is a conceptual example of how the vulnerability might be exploited. Note that the following is a simplified representation and does not represent actual exploit code.

POST /executeService HTTP/1.1
Host: vulnerable-ibm-webmethods.com
Content-Type: application/json
Authorization: Basic [Base64-encoded credentials]
{
"service": "affectedService",
"args": {
"formatString": "%s%s%s%s%s...%s%s%s%s%s; malicious_command;"
}
}

In this example, the attacker uses a format string attack. They pass a malicious command within a string of format specifiers. The system, failing to validate the string properly, executes the malicious command as part of processing the format string.
