IBM QRadar SIEM (Security Information and Event Management) software, which is designed to collect, normalize, and analyze security events from various sources, has been found to have a significant stored cross-site scripting (XSS) vulnerability. This flaw is identified by the Common Vulnerabilities and Exposures (CVE) system as CVE-2024-47107.

In this long-read post, we'll explore the details of this vulnerability, the impact it might have, a code snippet demonstrating the flaw, links to the original references, and potential exploit scenarios involving this vulnerability.

Vulnerability Details

The stored XSS vulnerability in question has been found in IBM QRadar SIEM version 7.5. Authenticated users can exploit this flaw to inject arbitrary JavaScript code into the software's Web UI. As a result, this injected code can alter the intended functionality, potentially leading to credentials disclosure within a trusted session.

Here's an example code snippet of the vulnerability

<!-- Vulnerable parameter -->
<input type="text" id="username" name="username" value="[Injected XSS Payload]">

<!-- Potentially injected JavaScript code -->
<script>
// Malicious JavaScript code goes here
document.getElementById('password').value = 'Compromised!';
</script>

In the code above, the attacker has managed to inject a malicious script into the "value" attribute of the "username" field in the application's interface. Once executed, this script can manipulate other parts of the user interface or exfiltrate sensitive information.

Exploit Scenarios

Although the vulnerability requires an authenticated user to exploit it, it can still have serious consequences if exploited successfully. Some potential exploitation scenarios of this stored XSS vulnerability include:

1. Credential theft: An attacker can use the injected JavaScript code to steal the victim's session authentication tokens or even their actual login credentials. This can potentially give the attacker unauthorized access to sensitive data and security event logs.

2. Data manipulation: With the ability to execute arbitrary JavaScript code, an attacker could alter the appearance of the user interface, manipulate the data being displayed, or modify the behavior of various application functions—all without the victim's knowledge.

3. Advanced persistent attacks: By injecting malicious JavaScript code into the application's trusted Web UI, an attacker can maintain persistence in the target's environment. This can be particularly dangerous if the attacker uses this access to gain further footholds within an organization's network.

4. Privilege escalation: If an attacker can use this vulnerability to compromise a lower-privileged user's account, they may be able to leverage their newly gained access to escalate their privileges further and execute even more damaging attacks.

Conclusion

The CVE-2024-47107 vulnerability in IBM QRadar SIEM 7.5 is a severe security issue that can have far-reaching effects if exploited. Organizations using QRadar SIEM should ensure they are running the latest patched version, and monitor their environments for any signs of this vulnerability being exploited. Additionally, organizations should strive to implement security best practices and strong access controls for users with administrator privileges to reduce the risk of such vulnerabilities being exploited in the first place.
